② When the degree of vacuum reaches a certain value, a siphon effect occurs and water passes through the filter layer from bottom to top to backwash the filter material.
③ The filter layer on the valveless filter continues to retain suspended solids, causing increased resistance and causing the water level in the siphon pipe to continue to rise. When the water level reaches the mouth of the siphon auxiliary pipe, the water falls from the pipe and passes through the pump. The trachea carries away the air that descends through the siphon.
④ When the water level of the flushing water tank drops to the siphon destruction tube, air enters the siphon tube, destroying the siphon effect, backwashing ends, and filtration restarts.
The above is a complete filtration and environmental protection process of the valveless filter. During the working process, the valveless filter discharges the sewage and filters out the pure water. It has filter inlet, outlet, flushing and drainage without any need. The valve operates automatically by hydraulic force.
