Woven Press Filter Belts are multi-functional filter belts with various textures and a wide range of air permeability, which can meet a wide range of dehydration, filtration, drying and other requirements.

The sludge Dewatering belt is a kind of press filter belt. It is designed for solid-liquid separation, especially sludge dehydration in the sewage treatment industry. 

The combination of high-quality polyester or nylon monofilament, weave type as well as the correct opening and permeability makes our process belts particularly effective and robust and guarantees resistance to abrasion and chemical influences. Because they are manufactured on heavy-duty looms and additionally reinforced through a thermal fixing process, press filter belts also boast a particularly high level of mechanical stability. 

It is suitable for press belt filters and various vacuum belt filters. PFM Screen press filter belts are ideal for belt presses, vacuum belt filters, and sludge dryers.

  Woven Press Filter Belts (Sludge Dewatering Belts)

The press filter belt operates as a key part of the belt filter press as it determines the actual output and quality of the filtration process. Our fabrics are made with reasonable weave structures and special yarns for different applications to achieve rapid draining and good filter cake release.

Use special stainless-steel seams, compared to conventional hook seams, blades and sludge distributors can glide over the seam area far more easily, and the special seam is stronger, more durable and possesses better running properties. Furthermore, the risk of damage to the seams is reduced to a minimum, the seam area is closed more tightly and product penetration is reduced.
