Custom GT Grease Trap Treatment – a Case Study

Custom GT Grease Trap Treatment – a Case Study This is a case study about the use of Custom GT Tabs in a restaurant grease trap. Custom GT Tabs are a biological grease trap treatment designed to reduce pump outs, reduce odors, and reduce maintenance of restaurant and food service grease traps. Custom Gt Tabs contain billions of beneficial grease trap bacteria. These bacteria have been specifically selected because of their enhanced ability to metabolize the fats, oils and grease (ReduceFOG) that accumulate in restaurant grease traps. Custom GT Tabs are a grease trap treatment manufacture by Custom Biologicals. Grease Trap Treatment Case Study Client Category: Restaurant Grease Trap – A potential client wanted to determine the effectiveness of Custom GT-Tabs versus the product that they were currently using. Location: A restaurant in Pennsylvania, USA Physical Plant: A single 1000 gallon greasetrap Problem: High BOD Grease accumulation, Bad odors Previous Treatment: Prior to treatment, a competitors product was used. BOD, Grease and odors were reduced but not reduced under the surcharge limit. Custom Treatment: Custom GT-Tabs, a grease trap treatment product, were applied directly into the greasetrap at a rate of 1 GT Tab every 2 weeks. Custom Results: The trap was not pumped during the testing period. BOD was significantly reduced to within acceptable parameters....

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...

Sewage Treatment Using a Lagoon – A Case Study

This is an interesting sewage treatment case study that took place in Mazatlan, Mexico. F-TREAT by Custom Biologicals is the product featured in this case study. F-TREAT is a biological wastewater treatment product designed to reduce BOD, COD, and FOG’s in sewage treatment plants, lagoons, and industrial wastewater treatment plants. In this case study, the wastewater treatment plant for  the city was overcapacity and there was no funding for a new sewage treatment plant. The decision was made to convert an existing, freshwater lagoon into a treatment plant. The conversion was simply plastic dividers to channel the wastewater in a circular motion around the lagoon. In this manner, we were able to increase the retention time inside the lagoon. As you’ll see below, this solution proved to be an inexpensive alternative to building a new sewage treatment system. Sewage Treatment Using a Lagoon – A Case Study Client Category: Municipal wastewater treatment plant. Location: Mazatlan, Mexico Physical Plant: The lagoon was about 300 Meter in length and 50 Meter in width. Depth was about 1.5 Meters. Baffles were installed in the lagoon to direct the flow of the wastewater Flow: 1.7 MGD (million gallons per day) overflow. Problem: Low reduction of BOD and COD. Overflow water with high BOD and COD overloaded existing municipal...

Municipal Wastewater Treatment Case Study

This case study is about municipal wastewater treatment. Specifically this wastewater treatment plant accepted grease from grease trap pumpers and attempted to pre treat the fats oils and grease (reduce FOG’s). After pre treatment, the grease would then flow into the main wastewater treatment plant and combine with the rest of the sewage. While good on paper, at this facility the pre treatment was not working properly. When released into the main treatment facility the  FOG’s were causing a number of sewage problems at the treatment plant. This case study show the use of F-TREAT, by Custom Biologicals, to solve this wastewater problem. Municipal Wastewater Treatment Case Study Client Category: Municipal wastewater treatment plant accepting liquid waste (FOG’s) from septic and grease trap pumpers. Location: Flagstaff, Arizona, U.S.A. Physical Plant: A 60,000 gallon holding tank was used for pre treatment to reduce the FOG, BOD and TSS before entering the activated sludge treatment plant. Flow: 1.4 MGD (million gallons per day) Existing Problems: Two air blowers required to aerate. Manual daily application of competitors enzymes and catalyst required significant time. Accumulating solids in tank. Heating to 85° F. required to keep grease from solidifying. Objectives: Use a more effective product – F-TREAT. Eliminate the use of one aerator. Reduce teh temperature below 65° F. Reduce...

Bioremediation of an Oil Water Separator – A Case Study

This case study is about the bioremediation of an oil water separator using Custom HC, a bioremediation product by Custom Biologicals.  Custom HC contains petrophilic, oil loving, bacteria. These oil loving bacteria have been specifically selected for use in bioremediation because of their enhanced ability to metabolize oil, petrochemicals, BTEX components and hydrocarbons. The addition of bacteria to wastewater is called bioaugmentation, a form of bioremediation. In this case Custom HC was added to the oil water separator. Bioremediation of an Oil Water Separator – A Case Study Client Category: Industrial Wastewater – Truck Maintenance Yard Location: Phoenix, Arizona, USA Physical Plant: Two 350 gallon holding tanks leading to a 4,000 gallon oil/water separator. Flow: 7,000 GPD average Problem:  TPH (Total Parts Hydrocarbon) level of 180 mg/L caused a surcharge of $7,000.00 per year. Pumping the oil/water separator monthly at a cost of $600.00 per month. Previous Treatment: Pumping the oil/water separator monthly at a cost of $600.00 per month. ustom HC was added daily to the holding tanks. A total of two 55 gallon drums were used each month. The product then flowed into the 4,000 gallon separator. Bionutrients were also added. Custom Treatment: Custom HC was added daily to the holding tanks. A total of two 55 gallon drums were used each month. The product...
