Heating Oil Spill Cleanup Using the Small Spill Kit

Heating Oil Spill Cleanup Using the Small Spill Kit

This post is a case study about the cleanup of a heating oil spill using the small spill kit by Custom Biologicals. The small spill kit is designed to clean up a number of small petroleum spills such as; heating oil spills, diesel oil spills, gasoline spills, and motor oil spills.

The small kit contains Custom HC. Custom HC is a bioremediation product containing billions of petrophilic (oil eating) of specifically selected, beneficial bacteria.

Case Study Heating Oil Spill Cleanup

Client Category: Emergency response – heating oil spill

Location: Pennsylvania

Problem: 275 gallons of heating oil located in the basement were spilled when an automobile struck the building. The basement was a dirt surface and about 900 square yards were affected. TPH levels ranged from 3500-9800 ppm.

Custom Treatment: The recommended dosage of Custom HC was applied directly on the dirt basement floor. Bio-nutrients were also added.

Custom Results: The following averages were obtained after six weeks of treatment.

Hydrocarbon Testing Site 1

Before –  3500 ppm TPH

After – 63 ppm TPH

Hydrocarbon Testing Site 2 

Before  – 9800 ppm TPH

After – ND (non-detectable)

As of the date this case study, the Pennsylvania Department of Environmental Resources (PA DER) had established standards for hydrocarbon contaminated soils of 200 ppm TPH. The final sample results are well within this criteria; therefore, no further corrective action was warranted for this site.

Know and follow the local and state laws when using the small spill kit.

Bioremediation of Produced Water FAQ’s

Bioremediation of Produced Water – Frequently Asked Questions.

What are the general characteristics of produced water?

Produced waters that are formed from gas production tend to have high concentrations of aromatic hydrocarbons, specifically the BTEX (Benzene, Toluene, Ethylbenzene, and xylene) compounds. Produced water also contains the chemicals used for gas processing such as; sulfide removal chemicals, dehydration chemicals, hydrogen sulfide reducing chemicals, and chemicals that inhibit hydrates. Produced water contains free product hydrocarbons, and a number of dissolved and dispersed compounds. Generally, produced water is placed into a holding pond.

What is bioremediation of produced water?

Bioremediation of produced water is the use of bacteria to metabolize the hydrocarbons and other petroleum compounds associated with produced water.

What are the major problems associated with produced water?

Generally, produced water is first treated to remove as much free product hydrocarbons as possible. While the goal is to reduce TRPH to below 100ppm, most treated produced water contains 300-400 ppm TRPH. Additionally, produced water contains saturation concentrations for any hydrocarbons present. These hydrocarbons can’t be removed by physical methods. Treating these remaining hydrocarbons is the major problem with produced water.

Also, as the produced water begins to evaporate, a number of problems develop. The hydrocarbons in the produced water begin to chemically interact with the water in the retention pond. Some of the hydrocarbons become heavier that water and sink to the bottom forming a sludge. Since anaerobic conditions are present at the bottom of the pond, anaerobic bacteria begin to digest the sludge. This anaerobic digestion produce hydrogen sulfide (rotten egg smell).

How does the bioremediation of produced water work?

We use Custom HC, our proprietary bioremediation bacteria, to bioremediate produced water. Custom HC contains specifically selected bioremediation bacteria. These bacteria have been selected because of their safety and their enhanced ability to metabolize a wide variety of hydrocarbons, petroleum products, BTEX compounds, TRPH compounds, and more.

Custom HC is available as a liquid concentrate and as a slow dissolving solid. application instructions vary so contact Custom Biologicals for more information.

The Bioremediation Waste Water Case Study in London

The Bioremediation of Waste Water – A Case Study in London

This wastewater case study is a little more involved than most of the information we have. It involves the initial assessment of the use of F-TREAT in bioremediation of waste water. Specifically, the removal of Fats, Oils, and Grease (FOGs) and other organic wastes from the sewer lines in London, England and prepared for the Thames Water Utilities, LTD.


The Piccadilly Line BioTreatment

The bioremediation treatment on the Piccadilly Branch Sewer was the second such treatment by the Thames Water Utility using F-TREAT and was carried out as a result of successful tests achieved from a similar biotreatment on the sewer in the Parliament Street area.

Wastewater Bioremediation London

Before Bioremediation

The bioremediation strategy was planned after careful evaluation of all of the site conditions Dose rates were calculated on the length of the sewer to be treated and the extent of accumulation of fats and other solids.

The length of the sewer  to be bioremediated covered approximately one kilometer and is estimated to have contained about 250 tons of FOGs and other organic solids. Sewage flow through this section of sewer was stopped for 6 of the 7.5 weeks of the F-TREAT treatment, a small input from local residences was inevitable.

The treatment of sewer by Custom Biologicals was carried out by the introduction of F-TREAT to the sewer line at three different entry points. Full dosing was carried out over 6 weeks followed by reduced dosing along with continued monitoring.

The tanks contained 200 Liters of concentrated F-TREAT which made a total of 2000 Liters when diluted for treatment purposes. The sewage line was monitored regularly throughout the treatment. Monitoring was conducted and a series of photographs and descriptive notes have been produced.

Discussion of Results

After wastewater bioremediation

After Wastewater Bioremediation using F-TREAT

It is apparent from the notes and photographs made from physical inspection of the sewer lines by the Thames Water staff, that treatment using F-TREAT had a profound effect on the transformation on the fats in the sewage line. This transformation initially took the form of an overall softening of the solidified fat and later by the solubilizing of the fat, leaving the organic waste in a crumbly state.

It is important to note that the test was not designed to provide complete cleansing of the sewer line during the initial 7.5 week treatment period. This would not have been possible due to the extreme fat buildup and lack of constant water flow. Normal water flow was reestablished after the 9th week and a blockage did not occur. The previous test on Parliament street sewer line produced a more complete cleansing but followed a longer treatment period of 12 weeks, with the existence of a constant flow and less fat buildup.

The treatment of the Piccadilly Branch sewer line is continuing under conditions of constant flow. The existence of a constant flow of sewage through the sewer lines is an important factor in the success of the biotreatment. Such flow of sewerage not only provides an aqueous phase for bacterial proliferation but also a constant supply of nutrients and a means of flushing away solubilized fat products from microbial metabolism, not to mention the physical turbulence helping to break up the fat.

Bioremediation of city sewer lines is a complex. Contact Custom Biologicals on how the process of bioremediation of wastewater can help your sewage system.
