Dry Municipal Biosolids Cake
Classification of Dry Municipal Biosolids Cake. Dry Municipal Biosolids Cake is composed of the remaining solids after residential wastewater is treated at a municipal wastewater treatment plant. At the treatment plant the material is subjected to two treatment processes:
Anaerobic Digestion: biosolids are stored in a tank where micro-organisms break down organic material in the absence of oxygen. The biosolids are partially stabilized in that the concentration of pathogens and the amount of biosolids are reduced; and
De-Watering: reduces the volume and improves handling characteristics. The biosolids are normally watered before disposal or re-use. Once dewatered, the biosolids turn into semi-solid cake-like form with a solid content of 25-35%.
