The purpose of the Agri-Clean System is to remove solids and nutrients from animal manure wastewater. The system consists of an Internal Drum Thickener (IDT), an Agri-Press Screw Press, a Dissolved Air Floatation Clarifier (DAF), a twin polymer make-down system, a chemical feed system, a PLC control, a data collection system and a telephone modem.
The IDT pre-thickens the low consistency, raw manure slurry to 10-12 percent solids. The thickened slurry flows into the Agri-Press and is dewatered to 35-40 percent solids. The liquid filtrate from the IDT and Agri-Press is pumped to a DAF clarifier. Chemistry is added to the liquid filtrate before being injected into the DAF. The chemicals are a coagulant and a flocculent. The coagulant is used to remove soluble phosphorus and ammonia while reducing the pH and neutralizing the negatively charged suspended solids. Solids from the DAF are returned to the IDT and Agri-Press.
Among other benefits, the system is said to cut down on the phosphorus and other residuals produced that can actually be detrimental to the immediate environment and it also offers odor control.
