Step 6 – Biosolids Handling

As a result of removing contaminants and pollutants biologically, and nearing the completion of the treatment process, there is an excess of residual matter, called “Biosolids”. The excess biosolids are removed from the system and require further treatment before ultimate disposal. The District employs large solids pressing machines which dewater the biomass to reduce the moisture content and allow the material to be placed in a dump truck where it is transported off-site for ultimate disposal in a private landfill.
