    Gravity type valveless filter siphon type backwash filter, siphon filter

    Valveless filters are widely used in surface water purification, circulating water side-flow filtration, removal of suspended impurities in production wastewater, and filtration of organic wastewater after biochemical and secondary sedimentation treatment. The steel valveless filter mainly uses the siphon principle to perform regular backwashing. The filter does not use a valve for water inlet, outlet, flushing and drainage, and operates automatically by hydraulic force.

    application

    Valveless filters are widely used in surface water purification, circulating water side-flow filtration, removal of suspended impurities in production wastewater, and filtration of organic wastewater after biochemical and secondary sedimentation treatment

    working principle

    The raw water enters the filter tank through the water pipe, passes through the filter layer to filter from top to bottom, and then enters the water storage tank. After being filled, it enters the clear water tank through the water outlet pipe. The filter layer continuously keeps suspended matters, causing increased resistance, which causes the water level in the siphon to rise continuously. When the water level reaches the siphon auxiliary tube nozzle, water falls from the tube, and the siphon drops the air through the suction tube to take away When the degree reaches a certain value, a siphon effect occurs and the water is backwashed from the bottom to the top through the filter layer. When the water level of the flushing water tank drops to the siphon damage pipe, air enters the siphon pipe, destroying the siphon effect, the back flushing ends, and the filtration restarts.

    Introduction

    The steel valveless filter mainly uses the siphon principle to perform regular backwashing. The filter does not use a valve for water inlet, outlet, flushing and drainage, and operates automatically by hydraulic force.
