Membrane filter press<\/span><\/strong><\/a>
Second squeeze dehydration: after traditional filtration, inject high-pressure water\/gas into the diaphragm plate, and the flexible membrane expands to pressurize the filter cake, further squeezing out the water. Optional: Some models support blow drying to strengthen the dewatering effect.<\/p><\/div>

Chamber Filter Press<\/span><\/strong><\/a>
One-way filtration and dewatering: only rely on the pressure of feed pump to push out the filtrate, the water content of the cake is high; No squeezing function: relying on natural filter cloth interception, suitable for low viscosity, easy to separate materials.<\/div><\/div><\/div><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
