Indion - Multigrade Filter- Brochure

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.
