With the help of the automatic controller, when all filtration tanks are in working mode, the dirty water enters with high pressure and is then evenly distributed through the unique distributor. The water passes through the filter, retaining all contaminants, after which the filtered water passes through collectors and is discharged evenly through the outlet.

- High filtration volume and low pressure loss
- The system has a built-in microprocessor controller that allows operation without human intervention
- Residual impurities can be automatically flushed, and the modules can be alternated while the remaining filters continue with the purification process
- Depending on the quality of the water, quartz sand or garnet can be used to perform a filter action. The minimum diameter should be up to 0.16mm
- The access port allows easy and convenient monitoring of the internal part during operation
