Water is the source of life. With the improvement of people's living standards, water consumption in all aspects is constantly increasing. Currently, water supply is becoming increasingly tight! The technology of the fully automatic self-cleaning filter of Beijing Lunji Company has become very mature, and the development of wastewater recycling and utilization has become a reality. With the continuous improvement of wastewater recycling technology, reclaimed water has been increasingly widely applied in industry, agriculture, municipal life and other fields, among which the proportion used for agricultural irrigation is the largest. Reclaimed water, with its low cost, also helps improve the ecological environment and achieve a virtuous cycle of water ecology. From the perspectives of technology, economy and approaches, it is one of the best ways to alleviate the water crisis.

The fully automatic self-cleaning filter adopts advanced equipment. Its filtration principle is mainly that when the sewage enters the filter, it is filtered through the filter screen. The impurities in the sewage are retained on the inner wall of the filter screen. When the impurities on the filter screen continuously increase and form a filter cake, a pressure difference will be generated between the inlet and outlet of the filter. When the pressure difference reaches the preset value, the pressure difference controller starts to act. Connect the drive device to rotate the brush. At the same time, the drain port opens. The brush rolls up the impurities on the screen wall. Under the effect of the pressure difference between the water pressure inside the filter and the external atmospheric pressure, as well as the vortex generated by the rotation of the brush, the impurities are discharged through the drain port. When impurities are thoroughly cleaned and the pressure difference disappears, the control system closes the drain valve and the motor, and the system returns to the normal filtration state. There is no need to stop the machine during cleaning. The entire process takes less than 60 seconds. The main water flow will not be interrupted because only a very small portion of clean water is diverted for backwashing.

The fully automatic self-cleaning filter will organically combine sewage treatment and recycling, reduce unnecessary costs, and minimize costs. The fully automatic self-cleaning filter truly reuses reclaimed water! It has alleviated the problem of water shortage in our country, promoted the transformation of urban water resources in our country, and accelerated the overall pace of economic development in our country
