Method to Eliminate Anaerobic Odors, Reduce Sludge Volumes and Increase Biologic Treatment Efficiency in Effluent Treatment Plants, 1996 Environmental Conference Proceedings

Objectives of this yearlong project have been to eliminate anaerobic odors, reduce sludge volumes and improve effluent treatment efficiency by using a patented additive which increases cellular metabolism for microorganisms that occur naturally in effluent treatment systems. The newsprint mill’s effluent treatment system combines aerated stabilization and an activated sludge plant. Changes noted in the system include a reduction of anaerobic odors from aerated basins, improved solids capture in the secondary clarifier by over 35% and reduced secondary wasted solids in excess of 70%. The biomass, originally showing old septic conditions, is now mainly bacteria, indicating a younger healthier sludge. No negative impact to effluent quality was observed. The plant can now operate with higher MLSS concentrations with good settling which lowers effluent BOD and TSS and reduces the volume of secondary solids.
