Looking for a reliable Multi Grade Filter in Nandambakkam Chennai? Our high-performance MGF systems remove impurities efficiently, providing clean and safe water for residential, commercial, and industrial use.Multi Grade Filter (MGF) is a highly efficient water filtration system designed to remove physical impurities in a graded manner. It works by retaining particles of varying sizes through the voids of the filtering media, ensuring clean and safe water for residential, commercial, and industrial applications.
The Multi Grade Filter operates on a simple yet effective principle. As water passes through the filter, the graded media layers capture suspended particles of different sizes. This ensures that both large and small impurities are removed efficiently. Moreover, the layered media structure allows for 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 arrangement creates a filter bed with optimum pore dimensions, which captures both large and fine particles from the water. Additionally, the filter provides efficient flow while maintaining 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, resulting in a pressure increase across the system. Once a predetermined pressure drop is reached, the filter automatically stops for cleaning.
Cleaning the filter is simple and effective. The backwash system removes accumulated dirt, while the filter is rinsed with raw or filtered water to restore performance. After cleaning, the filter is ready to return to service, ensuring consistent water quality.
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
Capacity ranges from 1,000 Liters/hour to 10,00,000 Liters/day, making them suitable for residential, commercial, and industrial applications.
