Wastewater contains nutrient-rich solids, including human waste, which can be treated and re-used to improve soil for agriculture and grass.
During the Aeration phase of Secondary treatment, activated sludge is pumped from the bottom of the Aeration Basin to the Sludge Lagoons. Matured sludge is then removed from the lagoon and processed through a dewatering machine called a “Centrifuge”.
The end product “Biosolids” is left to dry on a prepared bed before testing and clarification for its use.
