Quartz sand filter removes impurities from raw water to achieve water reuse. Filter is automatic operation and back-flushing, under control system of dp-switch (pressure drop), butterfly and PLC control system.

 

How does the sand 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.

Attentions in using

 

1. When quartz sand filter first into use, users should clean sand firstly, after that to start filtration.
2. Turn all operating valves slowly, to avoid water impact.
3. Keep sharp or hard things away from filter.
4. Keep away from fire and high temperature.
5. Make sure sand is clean when not using.

 

How to install sand filter

 

Before installing a quartz sand filter, please make sure the ground is strong and even. The space is big enough for connecting pipes, valves and repair.
The filter needs changes sands after using some time. Follow below steps one by one:
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.
