Filtrate water treatment as an option

Increasingly, the solid capture rate in the filtrate water is discussed. The requirement of guaranteed filtration efficiency in the filtrate of >99% required IEA to develop a filtrate polishing for sludge dewatering installations. The fully automatic filtrate water treatment consists of a special IEA rotary filter with mesh screen, including the associated measuring and pumping equipment. The thus separated solids can be derived separately or recycled into the circulation of the sludge dewatering.
