What happens to the solids components of the wastewater?
Through each step of the treatment process, depending on the level of treatment, solids are removed from tanks and may be taken to landfill or reintroduced into another phase of the treatment process for additional treatment. The final treated solids (sewage sludge) can be called “Biosolids” if they have been treated sufficiently to remove contaminants and meet requirements for use on agricultural land.
