Sludge Drying System

D. R. Sperry & Companyax filter press sludge drying system eliminates secondary operations and product variations with repeatable moisture levels from cycle to cycle. In addition, the system also reduces pathogens, air pollutants and disposal costs.

According to their manufacturer, the heart of D. R. Sperry & Companyax filter press is a series of heated and Teflon- or epoxy-coated aluminum or ductile iron, caulk and gasketed recessed chamber plates in which the dewatering and drying occurs. The slurry is pumped and packed at standard densities into the chambers for normal dewatering, then the chambers are heated electrically or with surplus low-pressure steam while suction is applied to the discharge ports. The actual drying time is set to achieve the desired level of cake dryness, according to the company.
