DOYEN belt fitler press can be generaly divided into two types: Environmental sludge dewatering belt press and spent grain dewatering belt press. Sludge dewatering press is one of the most efficient dewatering units which can be applied through organic and inorganic sludge to achieve required results at minimum operating cost, mostly used to dewater all kinds waste water sludge.
