Bioremediation using F-TREAT in Municipal Sewer Lines

Bioremediation using F-TREAT in Municipal Sewer Lines Use of F-TREAT The problem of grease and fat buildup (FOG’s) in municipal sewer lines creates a major monetary investment for its removal each year. Cleaning, therefore is carried out only in those sewer lines where blockage of flow is a major concern. Any new and economical method of alleviating the problem is of great value. F-TREAT, a bioremediation product, has demonstrated a potential to achieve the required results and can be used in the following situations. As a Complete Bioremediation Solution – Problematic sewer lines undergo an inoculation treatment to remove fat deposits such as those exemplified by the Parliament and Piccadilly Street Branch sewers.  As a pretreatment – Physical and mechanical fat removal methods can be made substantially easier by pretreatment of the sewer lines with F-TREAT. Trials have shown that F-TREAT can significantly alter the characteristics of FOG’s making it less sticky and more friable and aid in its removal by suction. As a Maintenance/Preventative Treatment – Physically, mechanically, or biologically cleaned sewers are susceptible to recurrent problems as soon as the fats start to buildup again. Maintenance dosing of a cleaned sewer will prevent FOG buildup by bringing about a continued solubilization of the fat before it can cause...

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. 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....

What are Microbial Products?

 What are Microbial Products? There are a number of products on the market that claim to be microbial products. So what are microbial products and how to they work? In the simplest terms, microbial products are composed of beneficial bacteria that are used to naturally, break down a waste product, environmental contaminant, or other complex organic compound. Typically, microbial products are used to clean fats, oils, and grease (FOG), to clean oil spills (as in bioremediation) or in agriculture to help provide nutrients to plants. Microbial products are effective in soil, water, and groundwater applications.   List of Microbial Products by Custom Biologicals   Beneficial bacteria, like all bacteria, work by producing substrate specific enzymes. Bacteria have the ability in their genetic material, to produce a wide variety of enzymes such as lipases (break down fats) and proteases (breaks down proteins). Bacteria are so efficient at producing enzymes that they are sometimes thought of as enzyme factories. These enzymes quickly solubilize various organic waste products making the waste available to the bacteria as a food source. The end product if this digestion is primarily more bacteria, carbon dioxide and water. Microbial products have a wide variety of uses including: Bioremediation – cleaning of petroleum and oil spills Wastewater Treatment...

Bioremediation of Oil in a Retention Pond

This case study is about bioremediation of oil in a retention or holding pond. I’ve run into a number of these types of projects through the years. Typically in the dry months, the pond has little to no water. Once a hard rain comes, the water in the pond has a oil sheen. Additionally, the water may or may not have a petroleum smell. This type of situation is perfect for bioremediation using bioremediation bacteria such as Custom HC. Custom HC is a microbial product manufactured by Custom Biologicals and containing petrophilic bacteria. Bioremediation of Oil in a Retention Pond Client Category: Bioremediation – Major Oil Company Location: Texas, USA Physical Description: A 30,000 gallon pond with oil contamination of 971 ppm (mg/L). Custom Treatment: A daily dosage of Custom HC, a microbial product, was applied directly to the surface of the pond. A total of one 55 gallon drum was used. Nutrients were added and two 3HP (three horsepower), two inch diameter pumps were installed to continuously circulate the pond contents for the purpose of aeration. Custom Results: The following results occurred within 30 days: The bioremediation of oil in holding and retention ponds can best be accomplished using Custom HC, a bioremediation product by Custom Biologicals. Custom HC is available as a...

Bioremediation of Petroleum Contaminated Soils – A Case Study

A case study about the bioremediation of petroleum contaminated soils using Custom HC, a bioremediation bacteria product. This case study is a quite simple illustration of the use of bioremediation bacteria to clean petroleum contaminated soils. Custom HC, manufactured by Custom Biologicals, is a bioremediation bacteria product. Custom HC contains petrophilic (oil-loving) bacteria selected because of their enhanced ability to degrade petroleum products, fuel oils, phenols and petrochemicals. The addition of bacteria with the intent of metabolizing petroleum or other chemicals is called bioaugmentation. Bioremediation of Petroleum Contaminated Soils – A Case Study   Client Category: Ex-situ Petroleum contaminated soil. Location: Dade County, Florida, U.S.A. Problem:  An underground leaking motor oil storage tank went unnoticed and unemptied for 15 years. Two batches of excavated soil were contaminated with motor oil. Contamination Size: The soils were removed resulting in two piles, batch1 and batch 2. Batch #1 208 cubic yards 18,000 ppm TPH (Total Parts Hydrocarbon).  Batch #2 178 cubic yards 8,530 ppm TPH. Custom Treatment: Soil was treated separately with 2 gallons of Custom HC per cubic yard. Nutrients were added according to recommendations and aeration was provided. From the graphs, it is easy to see that both piles were treated by 90 days after the start of the bioremediation of petroleum. While...
