How does the Dual Media Filter works Raw water passes inside water distributor into filter media layer (quartz sand), which let impurities stay at sand layer. Clean water flow out stably from water collector. When the pressure drop reaches the given value, the cleaning cycle is started. The rinse control start working at pressure drop value at 0.05-0.15MPa, return to 0.02-0.04MPa after back flushing.  Quartz sand inside tank mixed with coarse and fine sands. They are allocated above water distributor averagely. Even in back flushing, water consumption is little. 
Tank inside has rubber line and plastic line for option. It is for anti-corrosion, which ensure a tank can be used 10-20years. 
The completed filter control system has finished already in factory.

1.Take down control valve
2.Pour sand into tank, by covering a protective cover at the inlet to avoid sand inside
After replacing new sand, return control valve, connect tightly. Remember there's a pressure gauge, but not fasten it tightly. Make sure each pipe connection is correct and no leak.
