Bioremediation Examples – Hydrocarbon Impacted Wastewater
There are many successful bioremediation examples on this website. This is a case study about the bioremediation of hydrocarbon impacted wastewater at an industrial site.
Custom Biologicals – Custom HC
Custom Biologicals manufactures and distributes Custom HC, a microbial bioremediation products. Custom HC containing specifically selected microbes that have an enhanced ability to degrade hydrocarbons. Custom HC can be used in soil, water, wastewater bioaugmentation situations.
Client Category: Hydrocarbon Impacted Wastewater Treatment Plant
Location: Los Angeles, CA, USA
Physical Plant: Four 500,000 gallon clarifiers, a two stage 40,000 gallon flocculation/aeration collection tank and a 2,000,000 gallon lagoon. Retention time is 4-7 days.
Flow: 1,000,000 GPD average (Gallon per Day)
Problem: County surcharges for excess COD and TSS amount to an average $450,000/year. Volatile Organic Compounds (VOC’s) are offensive to adjacent neighbors.
Previous Treatment The use of polymers injected at the headworks
Custom Treatment Initial Treatment 3 – 55 gallon drums of Custom HC
Week One 22 GPD of Custom HC
Next Weeks 6 GPD of Custom HC
