The Quilton Hydraulic Dewaterer (QPH) is a device that performs the compacting of the rejects from the filtering of wastewater and displaces or raises them a short distance ( 1.5 m ). It basically consists of three parts:
a) Compacting area
It mainly comprises a piston that travels to and fro at slow speed through the interior of a tubular body mounted below an inlet hopper. The tubular body, at the outlet, is clamped to the friction or discharge pipe that compacts the waste and discharges it at a given distance or height from the compactor. Below the tubular body there is a tray for collecting the liquid extracted from the waste.
b) Hydraulic system
It consists of a hydraulic cylinder located inside the compacting piston and is driven by the hydraulic unit at a pressure that can range between 150 and 230 bars.
c) Control panel
It is used to operate the hydraulic unit, regulate the number of cycles per minute, adjust and control the thrust, etc.
