Multigrade Filter - Depth Filtration, Higher Flow Rates With Coarse And Fine Media Mix, Enhanced Filtrate Quality

Better filtrate quality at higher flow rates and

lower cost

The INDION Multigrade 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 - 30

m/h have been successfully obtained for treating

waters containing 50 - 25 ppm suspended solids

respectively to produce a filtrate with less than 5 ppm.

Special Features

- Higher specific velocity

- Raw water can be used for backwashing the filter.

Advantages

- Higher specific flow rate than conventional downflow

filters thereby saving on space and cost.

- Very little maintenance required.

- Lower backwash water requirement.

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