Looking for a reliable Multi Grade Filter in Poonthamalli, Chennai? Our high-performance MGF systems effectively remove impurities, delivering clean and safe water for residential, commercial, and industrial applications. The Multi Grade Filter (MGF) is a robust water filtration system designed to remove physical impurities in a graded manner, ensuring efficient water purification for all your needs.
The Multi Grade Filter operates on a simple yet highly effective principle. As water passes through the filter, the graded media layers capture suspended particles of various sizes. Consequently, both large and small impurities are removed efficiently. Additionally, the layered media structure supports higher flow rates compared to conventional filters, making it ideal for high-demand water treatment applications.

A Multi Grade Filter is a depth filter that combines coarse and fine media in a fixed proportion. This combination creates a filter bed with optimal pore dimensions, which captures both large and fine particles. Moreover, the filter maintains smooth water flow while providing excellent filtration performance.
When raw water enters the Multi Grade Filter, it passes through multiple layers of graded sand, fine sand, white sand, activated carbon, and pebbles. These layers work together to:
Retain suspended solids
Remove colour, odour, and organic compounds
Adsorb free chlorine through activated carbon
As filtration continues, the filter media gradually accumulates particles, causing a pressure increase across the system. Once the predetermined pressure drop is reached, the filter automatically stops for cleaning.
Cleaning the filter is quick and effective. The backwash system removes accumulated dirt, and the filter is then rinsed with raw or filtered water to restore its performance. After cleaning, the filter returns to service, ensuring consistent and high-quality water.
Our Multi Grade Filters are available in Mild Steel, SS, and FRP pressure vessels. They come with:
Manual or automatic multi-port valves
Butterfly or conventional valves for easy operation
The capacity ranges from 1,000 Liters/hour to 10,00,000 Liters/day, making them suitable for residential, commercial, and industrial water treatment.
