USE OF A MULTI LAYERED PARTICULATE FILTER FOR REDUCING THE TURBIDITY AND SDI OF WATER

摘要

The present invention provides the use of a water treatment system. The water treatment system includes a filter bed including layers of inert particulate material, such that, from the top layer to the bottom layer, the coarseness of the particles decreases while the density of the particulate material increases, for reducing the turbidity and/or SDI of water.
