Industrial filter cloth, filter fabric,filter media

Belt filter cloth is mainly applied to horizontal belt filter, belt filter press, monobelt filter. The 95 series filter belt and double layer monofilament filter cloth is our patent products. Manufactured with special raw materials and weaving technics, the cloths have good resistence to both acid and alkali. The dimensional stability is perfect because of the special style of the strenghth, tightness, thickness and etc.

Filter press cloth is mainly applied to filter press, including chamber filter press, membrane filter press, recessed, plate and frame, etc.

Monofilament & Multifilament filter cloth: have good air and water permeability.They have good ability to prevent the granules from blocking in the fabrics and the filter cakes can be peeled off easily, therefore, they can be used time after time.

P008MD-P120D double layer monofilament filter cloth are mainly applied to belt filters, other products can be applied to plate and frame, recessed and membrane filter presses.

For blet filter cloth, we have different options for joint/closure. We use 316L clipper to join two ends. To protect the clippers and make the belt run smooth, overlap cloth will be stitched over the clippers. see picture.

For filter press cloth, in order to ensure the tightness with filter plate, latex will be brushed at four round and also neck. For construction, we will sew rubber neck, banding/fastener, velcro, put metal eyelet, etc. See pictures.

1. How to select suitable type of filter cloth?

Filter cloth is increasingly applied by more and more industries such as chemicals, metallurgy, mining, food & drinks and pharmacy as an effective and affordable media of solid-liquid separation.

The filter cake will begin to become wet, slimy and not as dry. This is your indicator that the cloths need to be cleaned. If you have already cleaned your cloths and your process has not changed but you are still getting slimy filter cake, it may be time to replace your cloths. Cloth life varies from installation to installation and depends on such variables as frequency of cycles, proper cleaning and maintenance and the type of sludge that is generated.

There are several methods used to wash cloths while they are still installed in the press.  The most commonly used methods are acid washing and water washing.
