Optimum time cycle
High filtration rate can be obtained from producing thin cake. However, a conventional filter press is a batch system and the process must be stopped to discharge the filter cake and reassemble the press, which is time consuming. Practically, maximum filtration rate is obtained when the filtration time is greater than the time taken to discharge the cake and reassemble the press to allow for cloth's resistance.Properties of the filter cake affect the filtration rate, and it is desirable for the particle's size to be as large as possible to prevent pore blockage by using a coagulant. From experimental work, flow rate of liquid through the filter medium is proportional to the pressure difference. As the cake layer forms, pressure applies to the system increases and the flow rate of filtrate decreases. If the solid is desired, the purity of the solid can be increased by cake washing and air drying.Sample of filter cake can be taken from different locations and weighed to determine the moisture content by using overall material balance.
Polypropylene body plate
Macromolecule elastomer membrane plate
Macromolecule elastomer membrane filter plate consists of core plate and membrane with different materials, the core plate is made from modified polypropylene, the membrane is made from TPE materials. The core plate and membrane plate are compounded and formed through high-temperature melting and pressing by special plastic welder, featuring good elasticity, excellent sealing performance, high strength and free of water leakage. The sealing performance between filter plates are flawless, and air intake pressing will be adopted after the filtration, reducing the water content in solid.
