In many food wastewater treatment situations, except very dilute ones, suspended solids cannot be described as discrete particles of known specific gravity (a quantity that is the ratio of density of particle to density of water). ... Zone settling is mainly used in secondary clarifiers.Many wastewater treatment process designers use a batch. 4. Secondary Treatment.

High solid anaerobic digestion: Operational challenges and ...
The digester is operated between 23% and 28% TS with recycled digestate being mixed with fresh substrate. This is similar to the mixing in Dranco process and reduces the amount of fresh substrate fed into the digester. The principle of adding recycled digestate to the feedstock serves to retain an active microbial community within the reactor.
