A process for the treatment of contaminated fluid and wastewater containing residuals from food processing and waste and residuals from animal feeding operations and effluent from the digestion of these residuals is disclosed. The process is carried out in an enclosed tank using a separation procedure that maintains the state of the separated solids in the same state as they were upon introduction to the system, i.e., aerobic, anaerobic or anoxic, based on the condition of the solids upon introduction to the system. The system utilizes rotary flow instead of rakes to harvest the solids from the effluent. The process has applications in the recovery of emulsion in wastewater treatment and the operation of digesters for re-feeding to the digester.
