Recessed-plate filter presses are used to remove water from liquid wastewater residuals and produce a non-liquid material referred to as “cake”. Recessed-plate filter presses are among the oldest types of dewatering devices and can produce the highest cake solids concentration of any mechanical dewatering equipment. They are more commonly used in industrial applications than in municipal wastewater facilities.
