Other Details

The Multigrade Sand Filter is a depth filter that makes use of coarse and fine media mixed together in a fixed proportion. This arrangement produces a filter bed with adequate pore dimensions for retaining both large and small suspended particles. 

 This filter performs at a substantially higher specific flow rate than conventional filters. Specific flow rates of 15-30m/h have been successfully obtained for treating water containing 50-25ppm suspended solids respectively to produce a filtrate with less than 5ppm. 

Features

Higher specific velocity.

Raw water can be used for backwashing the filter.

Advantages

Higher specific flow rate than conventional down flow filters thereby saving on Space & cost.

Very little maintenance required.

Lower backwash water requirement.

In most cases, raw water can be used for backwash.
