High Rate Algal Ponds (HRAPs) with artificial addition of CO2 provide improved tertiary-level wastewater treatment over conventional HRAPs. One of the greatest challenges for performance and management of HRAPs with CO2 addition is the establishment of zooplankton grazers that can consume much of the algal biomass within a few days. High food availability and a near neutral pH provide optimal conditions...
High Rate Algal Ponds (HRAPs) can provide economical and efficient near tertiary-level wastewater (WW) treatment, with the nutrients recovered as algal biomass. HRAP performance can be negatively affected by the establishment of zooplankton grazers that can consume much of the algal biomass within a few days. Zooplankton management is therefore essential for maintaining WW treatment performance and...
