State of the art water equipment wholesale

The accumulated dirt in the filter after a period of use blocks the water flow and weakens it. At this time it is necessary to clean the filter. Turn the control switch position and the water flow will flow in the opposite direction. The water flow directly reaches the bottom of the filter chamber and then backwashes up through the sand layer to lift up the previously captured dirt and residue and discharge it from the sewage outlet. After each backwash The control switch should be turned to the R position to turn on the water pump. After a few minutes, it will be turned off and then the R position will restart normal filtration.

Product advantages of sand tank circulation equipment
The power-saving spherical shallow media filtration system has a unique automatic backwash valve. The backwash of the sand filter tank is not carried out at the same time but in turn backwashing one by one under normal operation of the system. There is no need to consider setting up a backwash pump. At the same time, compared with other sand filter equipment, the filter water pump lift required is lower.
Due to its unique water replenisher and water collector, the water-saving system has a unified tank size that does not require compressed air during backwashing, so that the medium layer can expand very evenly for effective backwashing. The water used for backwashing is filtered clean water, so the amount of backwash water consumed is small. The backwash water volume of a single tank is only /minute and the backwash time is minutes.
Save maintenance costs. The entire system does not have mechanical or electric valves and only relies on a unique multi-function valve to control the backwash of the system. Due to the unique multi-function valve, there is no wear and long life, no damage records during the year and low management costs.
