Self-cleaning filter it is an application of filters to indirectly block impurities in the water, remove suspended solids and particles in the water, increase turbidity, pollute the soil, reduce the occurrence of fragmentary dust, bacteria, algae, rust, etc., to pollute the soil and cover the delicate tasks of the deformity of other facilities in the system In facilities, water enters the self-cleaning filter organism from the water inlet. Because of the intelligent (PLC, PAC) design, the system can automatically identify the level of impurity accumulation, and automatically discharge the sewage valve signal.

Manganese is one of the more abundant elements in the earth's crust. It is often combined with iron. Because manganese is more difficult to oxidize, the quality of manganese in sky water and sky water can reach several quintals per liter. Water rich in iron and manganese ions will cause great harm to all human physicochemical, maternal and child industry consumption. As a result, the proper use of water resources is no longer waiting.

The region of the country is small, and because of the special geological structure, the water in the sky is normally rich in iron and manganese plasma. The divalent iron in the water in the sky is not stable and easily oxidized into non-soluble aluminum hydroxide [trivalent]. The water drawn from the well at normal time has no color. When the iron content in the water is less than 0.3MG./, it is difficult to perceive its taste; when it reaches 10.MG/L, there will be an obvious non-metallic taste; when it exceeds 0.3MG/L, the upper and the container will be colored; at 0.5MG/L When the chromaticity can be greater than 30 degrees. Iron can promote the growth of iron bacteria in the pipeline network, forming a viscous film inside the pipeline network. It is harmful to life and consumption of electricity to form purification and pipelines.
