Self-cleaning filter it is a very important equipment in the printing and dyeing industry, and we often apply it to pretreatment in water treatment. Its emergence makes printing and dyeing a healthy development industry, enabling the printing and dyeing industry to have a virtuous cycle of water use. The heat of high-temperature printing and dyeing wastewater can be better recovered through the heat exchange device to achieve the purpose of energy saving and emission reduction.

The issue of water for printing and dyeing has always been a concern for us. All walks of life have been looking for a water-saving and healthy water system. Because the printing and dyeing water consumption is large, the pollution is severe and the environment is seriously polluted. It has become a thorn in the eyes of our environmentalists. But the printing and dyeing process has reached a peak in the process. It is impossible to think about not using water to finish printing and dyeing. So we thought of using high-temperature printing and dyeing wastewater to carry out the printing and dyeing process. Afterwards, the high-energy waste water heat energy is recovered through a heat exchanger, and then the sewage is turned into usable reclaimed water, and then reused. The self-cleaning filter is now an important equipment process in the printing and dyeing heat exchange and heat recovery system.
