Gravity Filter

Description

There are "Valveless Type(VT)" and "Monovalve Type(MT)" of gravity filter. The VT uses No valve while the MT is operating with a single control valves. Both types are designed to operate automatically using the basic principle of pressure loss across the filter media.

The main system consists of backwash water storage tank, filtering chamber and filtered water collection chamber and filtered water collection compartment. Raw water flow down through one or more layers of the filter media. Solids and particles adhere to the media, clear water collects at the bottom.

Backwashing (removal of trapped fine particles and sediments)of VT is initiated automatically when the water level (height) reaches its preselected level. For MT filtration section, backwashing commences once the sensor detects the calculated head loss.
