The dehydration process is dewatering. The choice of polyester sludge dewatering fabrics is very important for dewatering performance, and the filter screen plays a key role in the application of the belt filter press. Its performance and the correct selection of the type directly affect the filtering effect. When water is separated from solids through a variety of different pumping or filtration processes, this process will be widely used in different industries, often referred to as construction and wastewater treatment plants. In wastewater treatment, dewatering is part of the process by which the volume of sludge can be reduced and converted from liquid to solid product.

 In order to achieve the ideal interception effect and filtration speed, the selection of the polyester sludge dewatering fabrics also needs to be based on the particle size, density, chemical composition and filtration process conditions of the slurry. Due to different weaving materials and weaving methods, their performance are all different. Therefore, our company created a herringbone net for the belt filter press. The herringbone design structure can quickly remove the sludge and mesh, it is not easy to immerse in the mud, it is not easy to accumulate a large amount of mud.

Advantage of the polyester sludge dewatering fabrics:

1. The surface of the polyester sludge dewatering fabrics is smooth, which makes the mud cake easy to peel off, and the filter belt is easy to rinse

2. The longitudinal of the filter belt is not easy to cause deformation, no arch, no wrinkles

3. Uniform monofilament,anti-wrinkle, strong flexibility,high tensile strength


The polyester sludge dewatering fabrics products are widely used in urban sewage treatment plants, paper mills, printing and dyeing plants, chemical plants, electroplating plants, pharmaceutical plants, food industry, ceramics plants, mining and other industries.
