The chambers of this type of Filter Press are formed by combining Polypropylene Filter Plates and Frames. This creates chambers of 10 - 50 mm, depending on frame thickness. Plate and frame type Filter Presses are suitable for pre-coating filtration, which in the beverage industry, is used for clear filtration. NMP supplies plate and frame type Filter Presses for operating pressures up to 6 bar.

High dry solids content in the filtration cake (higher than with the chamber filter press) => lower costs of transport and storage of the cake Shortened filtration cycle – compared to the chamber filter press it is possible to perform more filtration cycles over the same time. adaptability to the changing filtration conditions – e.g. differences in the suspended solids concentrations in the fed suspension Possibility of efficient washing of the filtration cake– controlled pressure of membranes ensured continuous flow of washing liquid through the cake. This ensures that the substances are washed out of the cake and the required purity is ensured. Smaller dimensions of the filter press given the same performance compared to the chamber filter press

We manufacture fully automated advanced filter press with plate shifting & plate shaker for autocake discharge along with plc based electrical control panel & pneumatically opereated control valves, flow sensor and hydraulically operated door drip tray. In this filter press initial filtration process takes place with the push of a button. Operator initiates filtration. Slurry is pumped into all chambers and cakes are formed as filtrate begins to flow. The end of filtration phase is automated by flow meter which is located on filtrate discharge pipe. The flow meter indicates the minimum flow rate of filtrate which is strictly related to the end of a cycle, the opening of filter press and the discharging phase a plate vibrating device during the discharge phase ensures 100 pct release of the cake. A plc controls the phases and cycle times for all the filter press functions including operation of the ancillary equipment

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.
