Valveless filter
Scope of application:
Steel gravity valveless filter series products are widely used in surface water purification, iron and manganese removal from groundwater, side flow filtration of circulating water, suspended impurities removal from production wastewater, subsequent filtration of organic sewage after biochemical treatment and secondary sedimentation tank treatment, and filtration of indoor swimming pool water. It is an ideal water treatment equipment.
Product features:
No valve, automatic operation by water conservancy, low operation cost, convenient management, safe and reliable, automatic operation
It operates automatically by water conservancy without valves, with low operation cost, convenient management, safety and reliability, automatic operation, equipment integration, integrated inlet water tank, filter and backwash water tank, compact structure, and users can put into operation only by making equipment foundation and connecting inlet and outlet water pipes as required. At the same time, the filter series products are equipped with a top cover, with good sanitary protection conditions, which can be set in the open air. Compared with the reinforced concrete filter, the self weight is small, and the asphalt sand flexible foundation is adopted.
working principle:
The raw water enters the filter through the water pipe, is filtered from top to bottom through the filter layer, and then enters the storage tank. After being filled, it enters the clean water tank through the outlet pipe. The filter layer continuously retains suspended solids, resulting in increased resistance, which promotes the continuous rise of the water level in the siphon. When the water level reaches the orifice of the siphon auxiliary pipe, the water will fall from the pipe and take away the siphon falling air through the suction pipe. When the vacuum reaches a certain value, siphon will occur, causing the water to backwash the filter material through the filter layer from bottom to top. When the water surface of the flushing water tank drops to the siphon, the air enters the siphon and destroys the siphon. The backwashing is completed and the filtration is restarted
