WATER
FILTRATION PROCESS
BACKGROUND:
Water in lakes, rivers, and swamps often
contains suspended and microbiological impurities that make it unfit for industrial and human use. Such water must be cleaned
using a water treatment plant before use. An important stage in
the water treatment is Filtration.
FILTRATION PROCESS:
The water passed through filter where all
suspended matter, organic impurities and bacteria are removed.
The filter can be made of Green Sand, Gravel or Manganese.

 Multigrade
Filters
Multi grade filters makes use
of a coarse and fine media mixed together in fixed proportions to form a filter
bed with appropriate pore dimension to block both large and small suspended
particles in the water.
These filters can be used to achieve
a flow rate from 0.2 m3 to 250m3. The filtered water contains 50-25ppm of
suspended solids. The filter requires very little maintenance. Normal untreated
water can be used to wash away the waste matter
from the filter.
