Aqua TruDense™ Provides Additional Capacity, Improves Settling, And Achieves Enhanced Nutrient Removal

When wastewater treatment facilities experience fluctuations in influent, achieving consistent and effective treatment can become a challenge. This case study details how the Cambridge, Wisconsin Wastewater Treatment Facility (WWTF) adopted a densified sludge process to improve its treatment capabilities. One of the WWTF's sequencing batch reactors was retrofitted to an Aqua TruDense Densified SBR reactor, which promotes the formation of larger and denser sludge flocs. This enhanced biomass stability improved settling even under variable loading conditions. The new process also improved nutrient removal, yielding lower effluent total nitrogen and total phosphorus levels compared to the conventional SBR system. This transformation resulted in a 20% increase in treatment capacity, showcasing the effectiveness of this advanced approach.
