Working Principle

  • VAG Filters operate automatically on the head loss principle.

  • The head loss at which the VAG initiates backwashing is determined by height of inverted U turn of the top of backwash pipe.

  • The level of water in this pipe is proportional to the head loss across the filter bed.

  • The Filter is divided into 3 chambers- Filter Bed Compartment, Filtrate Collection Compartment and Backwash Storage Compartment.
