What is a Multigrade Filter (MGF)?

• Definition of multigrade filter: a high-efficiency filtration system designed to remove suspended solids, dirt, turbidity, and particulate impurities from raw water.

• Works on the principle of deep bed filtration, where water passes through multiple layers of media (graded sand, pebbles, and gravel).

• Ensures high flow rate, low pressure drop, and longer filter cycle times compared to conventional filters.

• Integral part of Water Treatment Plants (WTPs), STPs, and ETPs.

Design and Working Principle

• Explanation of layered media design:

  • Coarse media at top (Anthracite/Gravel)

  • Fine media (graded sand) at bottom

• Flow path of water – downward filtration.

• Filtration process stages:

  1. Raw water enters filter.

  2. Suspended particles trapped in media bed.

  3. Clean water collected at outlet.

  4. Backwashing mechanism for cleaning the filter media.

• Diagram reference (like the one provided).
