Used for dewatering in sludge treatment plant. They have the characteristics of good water permeability, air permeability and non-revealed sludege, acid –resisting , alkali-resisting, heat resistance (180 degree C). Because of their designing structure , the sludge can be peeled off easily after pigeonhole filter, so the screen are easily cleaned and have a long working time. Therefore they are designed specially for sludge dehydration.
Filtartion fabrics for belt filter presses are characterized by high strength, resistance against abrasion and high dimensional stability.
Fabrics construction secures good water drainage and at the same time protects the sludge cake form going smoothness for easy cake release , resistance against abrasion etc.
Following is special design for this purpse .
