Advanced Lagoon Treatment Technologies for Wastewater Treatment
Lagoon-based wastewater treatment systems are popular around the world for their simplicity and cost-effectiveness. However, these systems are unable to reliably remove biochemical oxygen demand (BOD) and total suspended solids (TSS) to less than 30 mg/L or achieve nitrification during winter months in cold climates. Several innovative modifications have been developed, which have the potential to overcome these limitations by increasing the active biomass in the lagoons and managing the growth pressures associated with the microorganisms in the system. These technologies have been designed to support direct upgrades of existing lagoon-based systems without interrupting regular treatment.
