Sand filter for cleaning water from mechanical impurities, the filter material in this case is quartz sand.
These filters are distinguished by their high efficiency, they perfectly cope with suspended particles, microorganisms and other impurities contained in water.
Principle of operation:
Water is supplied through the water supply port to the main chamber, passing through quartz sand and exiting through the drain port, leaving unwanted particles on the sand.
When the impurities in the sand accumulate and the pressure difference between the inlet and outlet of the filter reaches a predetermined value, the controller sends signals to the three-way, solenoid valves of the control system.
The inlet channel closes and at the same time opens the outlet channel, after which unwanted particles are washed out of the sand by a reverse flow and exit through a special drainage of dirt. If necessary, the cleaning cycle can be configured in time.
