  Recommended procedures for testing the effectiveness of HydrobreakÒ

HydrobreakÒ has been designed to aid in the degradation of oils and hydrocarbons, below is a simple set of guidelines showing how best to judge the effectiveness of HydrobreakÒ as a an oil degrader.

The first step in any test is to determine the Total Petroleum Hydrocarbon (TPH) or Free Oil and Grease (FOG) content of a solution or soil sample before treatment with HydrobreakÒ. Once the initial TPH or FOG level has been determined, HydrobreakÒ can be applied to the solution or soil sample to aid in the degradation of the hydrocarbons present. 

If applying HydrobreakÒ to a solution containing oils or hydrocarbons it is important to remember the following points.

1.      HydrobreakÒ acts as a catalyst and therefore requires that certain conditions be met in order to achieve breakdown of the TPH.

2.      There must always be a source of oxygen present for the HydrobreakÒ to have an effect.

3.      The solution should be agitated in order to create the right conditions for breakdown.

4.      There must be bacteria present in the solution for breakdown to occur.

With the above in mind it is now possible to proceed.

The solution containing the oils or hydrocarbons should be placed in a beaker or jar along with water and a 5/10% concentration of HydrobreakÒ. The beaker containing the solution for breakdown should then be fed with a constant supply of air. This air supply will provide both the oxygen required and also the bacteria required.

The mixture should then be agitated constantly normally by way of a stirring device.

The mixture should then be left for a period of one day with the air and agitation in place at all times. After one day the mixture should then be tested for TPH and FOG levels, these results will probably not vary much from the initial readings, as the system has to develop into a bacteria rich solution.

In effect what happens is that the HydrobreakÒ in the solution will utilise the oxygen and bacteria present to develop a mini effluent treatment system containing a bio mass capable of degrading hydrocarbons.

A reduction in the TPH and FOG levels should be noticed after testing on the second day. The continual testing of the solution should take place each day until the solution reaches the desired TPH and FOG levels prior to discharge.

  Train cleaning using HydrobreakÒ Power

For the cleaning of heavily contaminated trains wagons and carriages HydrobreakÒ Power is an ideal product. It can be used to remove the heavy fuel oil and tar build-up that is often found on the walls of tankers and also on the under carriages.

  HydrobreakÒ Power should be applied using hot pressure jetting machines at approximately 50�C, it is always advisable to start washing from the top of the tank and work downwards. For best results the HydrobreakÒ Power should be left to penetrate for a period before rinsing off. Normally one application will be sufficient to remove the contamination, but in cases of extremely heavily contaminated surfaces it may require two treatments to remove all of the contamination.

It should be noted that whenever the application is to remove heavy oils and greases, that a better result will be achieved using higher temperatures. Where possible a temperature above the melting point of the oil and grease should be used. This helps the HydrobreakÒ Power put the oil or grease into solution to enable better breakdown of the contaminant. 

Combating oil spillage on the railways using HydrobreakÒ Power

HydrobreakÒ Power is a non-toxic, non-flammable product designed to clean up oil spills and oil contamination. It�s unique formulation ensures not only that there is an effective cleaning performance but also that the resultant waste is broken down into environmentally acceptable waste products i.e. carbon dioxide and water ensuring no subsequent damage to the environment.

HydrobreakÒ Power is formulated from a blend of organic based surfactants, organic acids, plant extracts and naturally occurring renewable organic solvents. This unique formulation prepares the oil contamination for treatment by naturally occurring micro-organisms found everywhere in the environment. It also acts as a stimulant for the micro-organisms providing a nutrient source which allows an accelerated growth rate, thus ensuring an increased concentration of the micro-organisms to allow degradation of the contamination.

The powerful formulation is effective even on the toughest types of oil based contamination such as tars and aged contamination, both from hard surfaces and porous surfaces such as concrete, gravel and sand.

  Track and Ballast Pollution

Oil polluted track not only leads to poor ballast formation. It is also a serious safety hazard; especially where there is a combination of slippery, oil covered sleepers or walkways and a live rail. Prolonged contamination of ballast by oil can also result in pollution of groundwater as well as adjacent rivers and streams.

HydrobreakÒ Power is particularly suitable for the removal of oil contamination from ballast and track-side areas. For heavily contaminated areas HydrobreakÒ Power should be sprayed using a steam cleaner if possible over the contaminated area at the rate of one part HydrobreakÒ Power to four parts water (20%); for lighter contamination a one to twenty (5%) solution should be used. After treatment the area should simply be left to allow the HydrobreakÒ Power to act. The treatment should be repeated once weekly, or until there is no more visible evidence of oil contamination.

In order to prevent a recurrence of the contamination build up a maintenance programme may be introduced whereby the area can be sprayed using a steam cleaner if possible on a monthly basis using a concentration level of 2% (1:50), or as otherwise indicated by visual evidence of contamination.

HydrobreakÒ Power will penetrate into the ballast and soil below and will continue to work therefore reducing the contamination levels in the soil below. In fact HydrobreakÒ Power will continue to work albeit more slowly, as long as there is hydrocarbon contamination present.

Other areas where HydrobreakÒ Power can serve a purpose within the railways.

Fuel storage tanks and bunded areas; for the removal of aged oil contamination from bund walls, concrete aprons and shingle-soakaways.

 Maintenance Depots and workshops; Workshop floors, gullies and equipment

Station and train halt areas; Emergency oil spills or derailments

  Fuel transfer areas; All areas where oils and fuels might spill onto

Train washing; for the removal of oily deposits on trains and undercarriages

For further details of application information please contact your HydrobreakÒ agent.

Good Housekeeping

As a general guide, common sense and elementary good industrial housekeeping can do much to reduce oil pollution. Set procedures should be laid down and adhered to at all times for the safe handling and disposal of fuels, lubricating oils even in small quantities. Likely sources of oil spillage or leakage should be identified and monitored and spills should be dealt with promptly should they occur. Oil residues in drums and containers should be removed promptly and never left around site.

HydrobreakÒ Power should be kept on hand and its use incorporated into standard anti-pollution procedures.

Disposal

Under the Environmental Protection Act all those involved in a spillage whether in production, storage, transport, treatment or disposal have a duty of care to:

�      Prevent illegal treatment and disposal of waste

�      Prevent escape of waste

�      Ensure that both the transport of the waste and its transporter are duly authorised

�       Provide a written description to accompany the waste

Ship cleaning with HydrobreakÒ Power

HydrobreakÒ Power has been designed to not only clean oily contaminated surfaces but also to convert the resultant waste into harmless by-products. This is of particular relevance to the marine industry where there is an increasing responsibility to ensure that the environment is protected from discharges accidental or otherwise of hazardous waste.

HydrobreakÒ Power is a most effective degreasing solution suitable for engine room degreasing, tank cleaning and bilge cleaning. Trials have shown that HydrobreakÒ Power will outperform most cleaner/degreasers available in the market place today.

To achieve breakdown of the resultant waste waters into acceptable components suitable for discharge it is recommended that all waste waters be placed into a holding tank where compressed air can be diffused through the solution over a period of time, this along with the ships motion will enable the HydrobreakÒ Power to break down the hydrocarbons present into water and CO2 prior to discharge.

The rate of degradation will depend on several factors, with breakdown to an acceptable level expected within 10-14 days.

Factors affecting breakdown:

�      Availability of oxygen

�      Ambient temperature

�      Level of contamination

A C.O.D. reading should be taken to ensure that the hydrocarbon contamination level prior to discharge is to an acceptable standard.

The correct use of HydrobreakÒ Power will reduce the high waste disposal costs, which are charged to ship owners.

Tank cleaning using HydrobreakÒ

HydrobreakÒ is particularly suitable for use in tank cleaning situations where there is hydrocarbon contamination, as it will not only clean the tank surface but also prevent the hydrocarbons reforming and will also enable the hydrocarbons to be broken down into environmentally acceptable waste.

In order to achieve the maximum efficiency from using HydrobreakÒ the following steps should be adhered to.

1.    Always ensure that the tank is gas free before commencing work.

2.    When cleaning the tank always use a steam cleaner if possible.

3.    The use of temperature and agitation will aid in the cleaning process and also aid in the degradation process by introducing oxygen.

4.    Use a water temperature higher than the melting point of the hydrocarbon to be removed.

5.    Always start cleaning the tank from the top and work downward towards the bottom of the tank.

6.    For heavily contaminated surfaces a higher concentration of HydrobreakÒ will be required.

7.    All resultant wastewater should be disposed of in accordance with local environmental regulations.

8.    In order to achieve hydrocarbon break down prior to discharge the wastewater should be placed in a secondary aerated tank and aerated until the hydrocarbon levels reduce with the action of HydrobreakÒ to a suitable discharge level.

9.    An ambient temperature of 25oC in the aeration tank will speed up the degradation process.

10.A TPH (total petroleum hydrocarbon) reading should be taken prior to discharge.

If the TPH levels remain high the solution should be left for a longer period of time, the addition of hydrocarbon degrading bacteria can also help the degradation process.

Filtration Cleaning using HydrobreakÒ 2000

A very common problem in the leisure industry today is that of inefficient filtration. This is generally caused be fat and grease build up in the filtration media.

A prolonged build up of fat and grease will lead to channelling where the filter eventually fails to clean the water passing through. This is due to the fact that a channel is formed and the water will pass straight through.

HydrobreakÒ 2000 has been proven to remove the fat and grease build up thus ensuring an efficient filtration system.

To remove the fat and grease from the filter using HydrobreakÒ 200 it is first of all important to isolate the filter unit.

HydrobreakÒ 2000 should then be added to the system at the rate of 5 litres per ton of filter media along with 25 litres of hot water. This mix should then be circulated around the filter for approximately three to four hours. After this period of time the unit should be flushed out to the drain until such times as there is no foam left. A noticeable difference should now be expected in the pressure differential between inlet and outlet valves. If the unit has not been cleaned out for a long period it may be necessary to repeat the application again.

In the case of smaller filtration units where the filter can be removed, it should be placed in a solution of hot water and HydrobreakÒ 2000 mix, with HydrobreakÒ 200 being added at the rate of 10% to the solution. The filter unit should be allowed to stand for a period of one to two hours then rinsed thoroughly using hot clean water.

  Cleaning in the Food industry using HydrobreakÒ 2000

Most food industry processes involve the use of oils, greases or fats as part of the process. It is often difficult to remove these fats without creating problems somewhere else. The biggest problem normally experienced is that of blocked drains and overloaded effluent treatment plants. HydrobreakÒ 2000 has been designed to alleviate both of theses problems.

HydrobreakÒ 2000 is a unique product which has been designed not only to remove oil, fat and grease deposits but also to aid in the degradation of such material, HydrobreakÒ 2000 also prevents the oils, fats and greases from solidifying once they have been removed from the contaminated surface. This ensures that the drains remain clear and fat free.

HydrobreakÒ 2000�s unique properties will also aid in the degradation of the hydrocarbon waste, it does this first of all by splitting the hydrocarbon molecules into smaller more readily digestible components. The next stage is that the HydrobreakÒ 2000 will feed the bacteria found in the drainage system and effluent digestion plants, creating a bacterial explosion. The bacteria are then more able to digest the waste converting it into environmentally acceptable by-products.

To clean down inside a food processing factory HydrobreakÒ 2000 is best applied using steam-cleaning equipment. Then the solution should be left to work for five minutes before rinsing down to the drainage system, again with steam cleaning equipment.

In order to sanitise after cleaning it is recommended to use a stabilised chlorine dioxide solution in the rinsing process this will ensure a sanitised surface. The use of a stabilised chlorine dioxide solution will also have the benefit of a residual sanitising effect over a period of time until the next shift gets underway. 

Using HydrobreakÒ to Aid in the Effluent breakdown process

HydrobreakÒ is a specially formulated product designed to speed up the breakdown of oils, fats and greases.

In an effluent treatment plant there is often a build up of excessive oils, fats or greases this is mainly due to larger than normal levels of oils, fats or greases, often caused by dumping. Whilst HydrobreakÒ is not recommended as the primary digestive source in cases of excess oils etc. it has proved to be a very successful aid when an effluent treatment system has larger than normal amounts of oils etc.

Where there is clear visual evidence of oils etc. floating on the surface of effluent treatment tanks, HydrobreakÒ can be used to assist in the breakdown process. HydrobreakÒ should be applied to the surface contamination by pressure washer; this will provide the required agitation.

Simple methodology for soil remediation using Hydrobreak �

It is now possible using modern technology and products to remove certain contaminants from soil and land using simple in-situ techniques. Every situation is different but below are details of a simple process, which will lead to a very substantial reduction in TPH (total petroleum hydrocarbon) levels from contaminated land.

Hydrobreak � has been designed to break down hydrocarbons into innocuous components with no resultant damage to the environment. It does this with the addition of oxygen and bacteria. The oxygen and bacteria can be found in most situations in sufficient quantities to allow Hydrobreak� to achieve a rapid and substantial breakdown of the TPH to acceptable levels.

The following is a basic method for decontamination of polluted soil. It is important to remember that all decontamination should be carried out to the satisfaction of the relevant authorities, where each authority sets it�s own levels of TPH permissible.

The first requirement is to establish the initial TPH levels and also the scale of the contamination. It is also important to determine the depth of the contamination, as this will have a bearing on the application of Hydrobreak �. If the depth of contamination is greater then 1 metre it is likely that there will be anaerobic conditions (no oxygen present) and therefore the soil will have to be dug up or a mechanical introduction of oxygen will be required. For simple remediation using Hydrobreak it is generally safe to assume that contamination to a depth of 1 metre is treatable using the following method.

1.    Dig over the soil using a rotovator or mechanical digger if possible to break up the soil and introduce oxygen. The soil should be dug over to the full depth of the contamination in order to achieve maximum effectiveness.

2.    A solution of one part HydrobreakÒ Plus or Power diluted with 19 parts of water should be applied by spray, watering can or backpack spray over the contaminated area at the rate of 50 litres of diluted product (2.5 litres concentrate) per cubic metre. This initial dosage will render the Hydrocarbons non-flammable and also break down the hydrocarbon chains into more readily degradable components.

3.    Take a further 2.5 litres of Hydrobreak Plus and again dilute with 19 parts water warm if possible (25oC) to give 50 litres of solution per 1 cubic metre of contaminated soil.

4.    Apply the solution containing the Hydrobreak in the same manner as before to the affected area, then dig over all the treated area once more as before and leave.

5.    After two weeks another TPH reading should be taken. This reading should show a large reduction over the initial levels.

6.    The treated area should be dug over once again at this point and left for a further two weeks. It is important at all times to keep the soil moist during the remediation process. Should there be drying out of the soil it should be watered at this point.

7.    After being left for another two-week period (four weeks from first application) a final TPH reading should be taken. Should the TPH levels at this point be above the authority�s recommended guidelines, and then steps 1 and 2 should be repeated.

8.    After a further two-week period final TPH readings should be taken to ascertain that the desired TPH levels have been achieved.

Important points to note:

�      Environmental conditions vary and these can have an effect on the rate of degradation.

�      Hydrobreak will perform at the optimal levels if applied when ambient temperatures are between 15oC and 30oC.

�      A moist environment must be maintained at all times during the remediation process. Watering of the treated area will ensure a moist environment at all times.

�      The remediation process will continue after the desired levels of TPH have been achieved, reducing further the contamination levels of the treated area.

�      The actions of microbial degradation will produce carbon dioxide, water and bacterial cells. The degradation process does not result in dangerous or toxic by products.

�      It may be appropriate for the introduction of small quantities of a simple fertiliser such as NPK (nitrogen, potassium and phosphorous) in order to maintain a good nutrient base for the soil during treatment.

Person responsible:       RNDr. Miroslav Kebrt

1.      Introduction

On the basis of order no. 18/10281 between the company ENVITOM s.r.o. and SCE a.s. dated 12.10.1995, decontamination of land in Lene� (Louny district) has been carried out in an area fronting a transformer sub-station.

      The area in question lies about 2 km NW of the parish of Lene�, to the right of the class 3 road from Lene� to Brvany.

      On 11.10.1995 there was damage to a transformer casing, and about 30 l of transformer oil (not containing PCBs or Cl) leaked into the soil in front of the transformer sub-station.

      The aim of the work was to use an "in situ" method to clean up the ground contamination by oil substances, or to reduce the concentration of the contamination.

2.      Decontamination work

The degreasing agent HYDROBREAK 2000, which breaks down oils and encourages bacterial activity with hydrocarbon decomposition, was used for decontamination of the ground in the "in situ" method.

      A quantity of 2 ltrs of this degreasing fluid, diluted at a ratio of 1:10 with water, was used to deal with the estimated amount of transformer oil which had leaked into the ground.  The diluted degreasing fluid was poured onto the place of spillage of the transformer oil.  This ensured natural absorption of the degreasing fluid by the same routes as the oil had followed.  The HYDROBREAK 2000 agent was applied 2 days after the accident (12.10.1995).

      Before using the agent for ground decontamination, a soil sample was taken at the place of absorption to check the level of contamination, and laboratory analysis of it established the content of oily substances in the dry matter using an infrared spectroscopy method.

      After 7 weeks (on 29.11.1995) the sampling procedure was repeated.  Pedological needles were used to take mixed samples of ground from the 0.0-0.5 and 0.5-1.0 m levels below the surface, and these were again analysed for their oily substances content.

      The data obtained from the analysis were compared with the "A", "B" and "C" thresholds given in the Czech Ministry of the Environment Guidelines as indicators and standards for decontamination of polluted land and ground water.  The values of the thresholds are given in table 1.  All the laboratory reports are given in Appendix 1.

      A shallow probe enabled the geology of the surface rocks to be specified, and the profile is as follows:

      0.0-0.2 m:      dump - sandy loam with pieces of brick and glass

      0.2-0.5 m:      dark brown sandy loam, humus

      0.5-0.8 m:      dark brown sandy/clay loam

      0.8-1.0 m:      light grey-brown fine-sand clay, compact

      It may be seen from the results of laboratory analyses of the samples that the petroleum hydrocarbon concentrations in the surface layer of land in question greatly exceeded category C in the Ministry Guidelines prior to application of the decontamination solution.  The content even exceeded the threshold of 50,000 mg/kg dry matter given in Appendix 3 to Czech government ruling No. 515/1992 Sb., on details of waste management.  Even soil for disposal on a group 5 dump (Hazardous waste) could not have been contaminated to this extent.

      Repeat soil sampling about 7 weeks later showed the oily substances concentration in the surface section of the profile to be still above category "C" in the Ministry Guidelines, but with the petroleum hydrocarbon value down by  several times.  Lower down, the soil was only contaminated at level "B" in the Ministry Guidelines.

3.   Conclusion and recommended measures

      Soil probing revealed impermeable or relatively impermeable clay from a depth of 0.8 m.  This layer may have served as a barrier to penetration of oily substances to greater depths.

      Mixed soil sampling after some 7 weeks of the action of HYDROBREAK 2000 degreasing fluid solution revealed a petroleum hydrocarbon concentration exceeding category "C" in the Czech Environment Ministry Guidelines in the top layer of the ground only.  This value is nevertheless several times lower than it had been prior to application of the solution.

      The lower section of the ground examined featured no more than level "B" in the Ministry Guidelines.  There are two explanations for this level: either the transformer oil did not penetrate deeply into the ground, or else it may have been that at the time of year when the top layer freezes quite often, the conditions for decontamination of deeper layers were more favourable.

      In view of the success of this method, where a fall by almost 4.5 times in the oily substances content in the soil was achieved under not particularly favourable weather conditions, we recommend taking further soil samples in the spring of 1996. In the event that the level of oily substances in the soil has not fallen below the Ministry Guidelines category "C" threshold, the degreasing agent may be applied one more time.
