Semi automatic filter press

each fitted with a durable permeable cloth. The recessed plates are pushed together in normal operation. The pressure required for dewatering is provided by the feed pump. During the filtration cycle the sludge is initially pumped into the chambers at a high rate. This rate is reduced as the chambers are filled and the pressure builds. The cloths retain the solids, allowing water to pass through as filtrate. Once the pressure in the press reaches a set point and the filtrate is reduced to a trickle the dewatering cycle is complete. The next stage of the process is to empty the press by opening the plate chambers and allowing the dewatered cake biscuits to drop out. This entire operation can be a manual, semi automated or fully automated process. Once the press is empty the plates are returned to the closed position, ready for further batches. The manual filter press unit is fitted with a hand pump, and is ideal for small sludge volumes. The semi-automatic filter press range, with a hydraulic pump for plate pack closing. The fully automatic machine includes automatic plate shifting, plate vibration and drip trays. A number of options are available to assist ease of operation for all models, including the Air-Track plate shifter, membrane plates for increased filtration pressures.
