Gravity type valveless Filter

A. The main parameters

Average filtration rate: 10m / h, water SS≤20mg / l, water SS≤3mg / l, the average intensity of backwash 14-15L / S m2, backwash time: 5min, media story: 700mm, supporting storey 300 mm.

Second, the principle

Steel Gravity type valveless Filter products are widely used in the purification of surface water and groundwater in addition to iron and manganese near the circulating water flow filtration, wastewater in addition to the suspended impurities, organic sewage through biological treatment and secondary sedimentation tanks after subsequent filtration and indoor Swimming pool water filtration, water is an ideal process equipment. Electrical apparatus equipped with a fridge, Filter, V-type out of the water pipes, drainage boxes, assembled into one, compact structure.

Raw water from the inlet pipe into the filter, the filter layer filter from top to bottom, that is storing water from the water storage tank communicating pipe injection, after the tank is filled, the water through the outlet pipe into the clean water tank, filter layer continued retention of suspended matter, resulting filter increasing resistance layer, which has prompted the rising water level within the siphon.

When the water level reaches the siphon tube when the auxiliary port, water falling from the tube through the exhaust pipe so as to fall away siphon tube in the air, when the degree of vacuum reaches a certain value, then the siphon effect. Then water in the water from the bottom up through the filter layer of filter backwash. When the flush tank below the surface down to siphon tube, air enters the siphon, destroy the siphon action. Backwash ends, into the next cycle of work, like other Filter should be without it, you must set the backwash pumps and backwash water tower.
