System Overview

Filter presses are highly efficient for removing water from sludge. Filter presses operate on feed pressure and can be used for high volume separation of solids from slurries, utilizing recessed or membrane plates. When the wastewater passes through the filter plates the discharge system and the filter medium retain the solid particulates. The wastewater slurry is continually fed into the system until all the water is squeezed out. The remaining solids form a dry cake and are collected in a basin prior to disposal.
