gravity valveless filter
1, average filter speed: 10 m / h
2, when the average reverse wash strength: 15 litres/m 2 second
GWL Gravity valveless filter for wastewater treatment
Basic principle: The raw water into the feed line by viewing, the filter layer since the but shangdi filtering, clear water that is, from LianTongGuan into the carry water storage tank filled, water through the pipe into the QingShuiChi. Filter layer continuous intercept suspended solids, cause filter layer of resistance increases, and thus make the water continued to rise siphon tube. When the water level to siphon auxiliary tube lu, water from the pipe down, and through the smoke to siphon away down the trachea pipe in the air, when the vacuum degree to a certain value, occurs siphon role. At this time the water conduit through bottom-up filter layer, the filter materials reverse wash. When the water washing water tank dropped to siphon damage pipe, air into the carried, destroying the siphon role. Viewing a reverse wash over, into the next cycle. There is no need, as the other filters that, must set reverse wash water pump and reverse wash water tower. This series filter products of large size, and the kingdom of the inversion between kikuchi map reinforced concrete gravity no valve than viewing, increased each group of big three series, the final head loss largest permissible value consists of the countries of the inversion between kikuchi map 1.70 meters increased 1.50-and 1.90 meters two grades, and for the removal of the elevation layout design provides convenient choice of products. Design parameters 1, average filter speed: 10 m / h
2, when the average reverse wash strength: 15 litres/m 2 · seconds 3, reverse wash for 5 minutes 4, the final head loss value: 1.50 m, 1.70 m 1.90 meters (three gears choose) 5, reverse wash inflation height: 700 x 40% plus 100 mm high safety 6, filter material layer height: 700 mm thickness of supporting 270 mm 7, water turbidity: not more than 20 degrees (used for surface water purification) 8, effluent turbidity: no more than 3 degrees (used for surface water purification)
