How the Filter Works

General: It is a small and lightweight yet durable filter; quick and easy to install, simple to operate and requires minimal maintenance. The filter was developed to handle low pressure operation, with capacity of upto 80 m3/hr and with filtration degree from 80-500 microns.

Filtration Process: The raw water enters through the filter inlet and passes through the screen. The clean water flows through the filter outlet. The gradual dirt built up on the screen's inner surface cause a filter cake to develop, creating an increase in the pressure differential across the filter system. A DP switch senses the pressure differential and when it reaches the preset level, the self-cleaning process begins.

The Self-Cleaning Process: The self-cleaning cycle is initiated by anyone of the following conditions:

1. Signal from the DP switch

2. Time interval parameters set at controller

3. Manual start, triggered by the mobile app

The flush valve opens to the atmosphere creating a strong suction force at the scanner nozzles, effectively removing dirt particles from the screen and discharging them from the filter.
