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...

Wastewater Bacteria and Their Importance in Treatment of Sewage Part 1

The Importance of Wastewater Treatment Bacteria at a Sewage Treatment Plant – Part 1 It is important to remember, and often overlooked, that the real work at the sewage treatment plant is done by the wastewater treatment bacteria and other microorganisms. Bacteria are single celled organisms that multiply by binary fission; that is one bacteria cell divides into two and two into four, etc. With an adequate food supply, bacteria are capable of reproducing every 20 minutes. To illustrate to yourself how fast this cell reproduction can be consider that once every 20 minutes means three cell divisions per hour. So get a calculator and hit 2 times 2, times 2, times 2, etc. After a mere seven hours, that initial wastewater bacteria has the potential to multiple into over one million bacterial cells. This amazing growth at a wastewater treatment plant is generally fueled by two things; adequate food supply and adequate oxygen supply. As a quick footnote, I’m not suggesting that all wastewater bacteria require oxygen but generally the aerobes grow at a much faster rate. Additionally, other factors such as temperature and pH will effect the growth rate of wastewater bacteria. For the purposes of this post, we’ll assume that the sewage plant is operating under...

Custom HC – Bioremediation Bacteria Product

Custom HC – Bioremediation Bacteria Custom Biologicals, Inc. produces Custom HC, a bioremediation bacteria product formulated to degrade petroleum hydrocarbons, dry cleaning fluids, chlorinated solvents, and other hazardous environmental contaminants in soil, water, and groundwater applications. Custom HC contains live, petrophilic (oil loving) bacteria. These bioremediation bacteria have been specifically selected because of their enhanced ability to metabolize (eat) petroleum products such as; fuel oils, phenols, diesel, BTEX components, heating oil, antifreeze constituents, and more. Bioremediation is the process of using bacteria, fungi, or other microorganisms to degrade selected pollutants and return the soil or groundwater altered by the contaminants to their original condition.  Bioaugmentation is bioremediation with the application of laboratory grown organisms like Custom HC to increase pollutant degradation, reduce cleanup time, and reduce costs of nutrients, machines, and manpower. Bioaugmentation is bioremediation with the application of laboratory grown organisms to augment the populations of bacteria that can degrade oil.  Degrade oil with Custom HC.  Custom HC has petrophilic bacteria, scientifically chosen for their ability to effectively degrade hydrocarbons, packaged in extremely high concentrations. Bioaugmentation with Custom HC will:         increase total petrophilic bacteria counts         increase effective petrophilic populations         decrease cleanup time   (and time is money)...

Custom GT Concentrate Grease Trap Bacteria

Custom GT Concentrate – By Custom Biologicals A Grease Trap Bacteria Formulation Designed for Distributors Custom GT is our grease trap bacteria product. The bacteria in Custom GT have been specifically selected because of their enhanced ability to metabolize the fats, oils, and grease (FOG) that are found in restaurant grease traps. All restaurants have have issues with Fats, Oils and Grease (FOG), grease traps, and grease trap odors. Typically restaurant owners will pump the grease trap, an expensive, smelly, and messy procedure. In fact, grease trap pumping is becoming more and more expensive and pumping of the grease trap only moves the problem from one place to another. Other restaurants will use chemicals and enzymes. These products simply move the problem down the sewer line. That’s why they are not allowed in some municipalities. Custom GT is a grease trap bacteria product. Regular use of Custom GT will greatly reduce the need for grease trap pumping. Here’s a case study of the use of Custom GT in a grease trap in Houston, TX. Custom GT comes in two formulations; GT Tabs and GT Concentrate. GT-Tabs are a ready-to-use product, slow release tablet. GT Concentrate is a concentrated form of Custom GT and it’s specifically designed for distributors. By shipping...

Bioremediation of Chicken Processing Wastewater – A Case Study

This case study is about the bioremediation of industrial wastewater, specifically the bioremediation of chicken processing wastewater. Food processing wastewater is one of the most common industrial wastewater problems that we work with at Custom Biologicals.  F-TREAT is the product highlighted in this case study. F-TREAT is a biological wastewater treatment product designed to reduce FOG, reduce BOD and COD, reduce odors, and reduce sludge at industrial and municipal wastewater treatment facilities. F-TREAT contains specifically selected bacteria. These bacteria have been selected because of their enhanced ability to metabolize the organic components at wastewater treatment plants.  Bioremediation of Chicken Processing Wastewater – A Case Study Client Category: Industrial Wastewater – Chicken Processing Plant Location: Georgia, USA Physical Plant: 3.5 million gallon pond and 0.9 million gallon settling pond Flow: 230,000 GPD (Gallons per Day) Problem: The protein conversion plant (rendering plant) has a LAS permit (Land Application System Permit) that allows the rendering plant to spray the treated water from the final settling pond onto fields at a rate limited by the phosphorous levels in the water. The phosphorous level was at the maximum allowable limit. Previous Treatment: Chemically treated for reduction of BOD and grease. There was not a phosphate removal system. Custom Treatment: An initial “shock” treatment of 110 gallons of F-TREAT with a daily application...
