Printing And Dyeing Wastewater Treatment Filter Press

Use Sudong reinforced polypropylene plate membrane filter press: no need to add lime powder; water content can be reduced to below 60%.

1. The harm of printing and dyeing wastewater

Printing and dyeing wastewater is a kind of industrial wastewater that is difficult to treat. It has the characteristics of large water volume, high content of organic pollutants, large alkalinity, and large changes in water quality. The wastewater contains dyes, slurries, additives, oils, acid and alkali, Fiber impurities, sand substances, inorganic salts, etc., can be reused only after the organic matter and chromaticity in the wastewater are deeply treated. A large amount of waste water discharged during the treatment process will be processed by the filter press after undergoing biochemical or physicochemical treatment.


2.The advantages of Printing and dyeing wastewater treatment filter press

Use Sudong reinforced polypropylene plate membrane filter press: no need to add lime powder; water content can be reduced to below 60%.

Advantages of Printing and dyeing wastewater treatment filter press

A customer in the printing and dyeing industry uses the XAYZG100/1000-U produced by Sudong Company, and only needs to adjust the flocculation ratio appropriately, and can directly use the feed pressure of 0.8Mpa to feed. When the feed is finished, the filter residue is filled with the filter chamber. Use pressure water or compressed air not exceeding 1.4Mpa to inject the empty stomach formed between the self-contained diaphragm and the core plate of the filter plate to bulge the diaphragm and squeeze the filter residue in the filter chamber. The water content of the filter cake can be reduced to below 60% , To achieve the same effect as adding lime powder, saving about 5% of the cost of adding lime powder, and further reducing the cost of post-processing filter cake.
