• ARCK's automatic backwash filtration system is composed of more than two ARCK's backwash filtration units. quipped with hydraulic backwash valve and automatic controller, it is a fully automatic water filtration system. The working flow of the system can be selected between 40m³/h and 630m³/h, and the filtration precision can be selected between 20-600 microns. Suitable for medium or high flow filtration needs.

APPLICATION SCENARIOS ：

• Agricultural irrigation -- applied to farmland irrigation. Filtration of sediment from water extracted from ponds, rivers and lakes. Make sure that the drip pipes and nozzles in the irrigation system are not blocked by sediment.
• Garden Irrigation -- Applied to garden greening irrigation, or circulating water filtration of waterscape projects.
• Industrial Filtration -- Applied to the filtration of circulating water in industrial production.

• Filtering : Under the command of the controller,the dirty water flow into the filters in filtration stage via the back-flushing control valves,then the Vortex and the disc keeps the particles in the groove of the discs,the clean water flow into the outlet pipe.

• Backflushing : At the command of the controller, one of the backflush control valves changes the direction of water flow. The filtered water is directed into the filter unit to flush the filter element. Solid impurities are discharged from the sewage pipe. The system will not automatically return to filtration stage until each filter unit is cleaned one by one.
