Features of Filter Cloth                                                                  
1. Filter cloth is used for sludge dehydration in sewage treatment factories. They have the characteristics of good water permeability, air permeability and non-revealed sludge, acid-resisting, alkali-resisting, heat resistance (180°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.
2.Filtration fabrics for belt filter presses are characterized by high strength, resistance against abrasion and high dimensional stability. Fabric construction secures good water drainage and at the same time protects the sludge cake form going through the fabric. Individual fabric designs differ in speed of dewatering, size of apertures, surface smoothness for easy cake release, resistance against abrasion, etc.
3. Fabrics for belt filter presses are equipped with stainless steel clipper seam and belt edges are melted. There is also the possibility to connect the fabric onto endless belt by using a woven seam, which is stronger and has a higher lifetime than clipper seam.

Can we clean the cloths with a pressure sprayer?                          

You can, but take care to not get too close with the spray tip. Only use the sprayer in a "fan" spray pattern and keep spray pressure under 1000 PSI.

Can we clean cloths with chemical cleaners?                                  
Polypropylene filter cloths can handle both caustic and acidic solutions. Nylon, polyester, and felt cloths need special consideration and may be damaged from these chemicals. Contact M.W. Watermark about your specific situation.

How can we extend our cloth life?                                                  
1) Filter cloth life is shortened by chemicals, mechanical wear, abrasion, and blinding. We can help to determine whether your cloths are being attacked by your process chemicals. Mechanical wear can be reduced by using a more durable cloth. Blinding often comes from "slamming" sludge into the press.
2) Consider an Auto Feed Pump Control System, or an AFPCS to automatically and gradually increase pressures. "Pre-coating" a press with DE or similar products can also add substantial life to cloths. The coating protects against wear and minimizes blinding.
