The integrated sewage treatment plant has several layers of filtration

Acid and alkali resistant filter bags: suitable for working environments with acid and alkali contact, such as phosphate fertilizer production, alumina industry, catalyst (4A zeolite) and other industries. When rubber is mixed with rubber and filled with inert data, the acid and alkali resistance are better than neoprene, and it has excellent acid and alkali resistance. The skeleton data is polyester canvas, which is more reliable in acid and alkali resistance than the surface canvas core. The drainage holes are made of pure glue, so that the acid-base solution cannot enter through the distribution layer, which leads to the layering of the filter belt and reduces the service life of the filter belt.

Heat-resistant filter bag: mainly used for filtering high temperature materials, 80℃<180℃. The basis for reflecting the loss of work ability is the damage of the heat belt. For different heat resistance grades, EPDM rubber or styrene rubber is used as the masking glue, the frame data is made of high-strength polyester canvas, the heat-resistant glass cloth between the cover plate glue and the frame layer, and the liquid hole is made of heat-resistant pure rubber layer, blocking high temperature damage to the skeleton. The life of the heat-resistant filter element is greatly improved.

Oil-resistant filter bag: The buried integrated sewage treatment equipment uses high acrylic fiber content and high nitrile finishing rubber as the main data, and selects polyester canvas as the skeleton data. It is suitable for filtration, oily materials, and various working oil environments. It has a volume change rate It has the advantages of low strength, high strength durability, and wide application range.

Cold-resistant filter bag: with polyester canvas as the core, natural rubber and butadiene rubber as the cover rubber, it has the characteristics of high elasticity, impact resistance and cold resistance, and can be used normally at -40 ℃.
