Grease eating bacteria - contains billions of aerobic and anaerobic bacteria that destroys malodors by eliminating the source. Bacteria produce enzymes to digest the waste naturally, feeding on fats, oils and greases as well as solids. As a drain treatment, reduces BOD (Biological Oxygen Demand) and reduces grease build-up in pipes and grease traps. Better BOD, TSS and COD levels in 60 days.
