The filter press system is employed by large concrete producers that need to recycle clean water as well as concrete waste. Our filter press systems allow these operations to produce dry cakes and usable clean water, realizing a zero waste and zero discharge process. This concrete recycling system adopts PLC automatic control, its flap board prevents water from drop ping onto the muddy cakes. Moreover through the electric slurry valve, the discharge of slurry water can be separated from the clean water.
