It is widely used in commercial golf course and sporting field irrigation, industrial pre-treatment for UF/RO, wastewater recycling, HVAC cooling towers, metal processing plants, and mining water cleaning.

Q:How does the automatic backwashing process work?

The system uses a pressure differential switch to sense when pressure reaches a preset value. It then signals the controller to start backwashing, where pressurized water flows in reverse to suspend the filter bed and wash out dirt particles through the back-flush valve.
