BIOLOGICAL TREATMENT OF DAIRY PLANT WASTE-WATER

The influent and effluent wastewaters of a Sequencing Batch Reactor (S BR) wastewater treatment system used by a dairy processing plane were evaluated over a two-month period. Pollution parameters measured were biochemical oxygen demand (BOD), chemical oxygen demand (GOD), total s uspended solids (TSS), total solids (TS), and pH. Viable biomass of th e samples was determined by adenosine triphosphate (ATP), measured in Relative Light Units (RLU) and heterotrophic plate count (HPC). The fo llowing average overall reduction of pollution parameters was achieved by the SBR system: BOD, 99%; COD, 93%; TSS, 97%; and TS, 76%, Biochem ical oxygen demand was highly correlated with GOD, TS, TSS, HPC, and A TP in the effluent, A significant correlation was also observed betwee n ATP and HHC. The pM of the influent and effluent ranged from 7 to 8. The average daily effluent flow rate of the waste disposal system was approximately 94,625 liters with an average BOD of 8mg/l, coo of 72mg /l TSS of 15mg/l, TS of 728mg/l, and pH of 7.62. With the efficient re duction of BOD, COD, TS, and TES, the SBR system was effectively used for the primary and secondary treatment of wastewater.
