Abstract

Sourcing the clean water has remained of the great importance ever since the civilisation has come into
the existence. Continuous efforts are being made to find out the innovative methods and techniques to
treat water efficiently and economically. In this study, an attempt is made to make efficient water filter,
to be used at large scale in water treatment plants, economically and commercially viable. It is made
from activated carbon coated sand acquired from thermal degradation of sugar on river sand particles.
The carbon coated sand is activated by chemical treatment. It is found that filter function satisfactorily in
removing the TDS and dissolved organics from polluted water. The high concentration of carbon on sand
have better adsorption power (15% sugar on sand is better than 5% sugar in sand) and higher the number
of passes through filter facilitate the better results. Though “ordinary sand” used in conventional systems
is good in removing organics but do not removes inorganic dissolved particles. It also could be done by
this type of filters. Higher amount of chemicals used in every sector reach back to the prime sources of
water. Which requires to be “re-treated” by water treatment plants. Thus, it becomes a necessity to find
out innovative techniques to treat water.
