Abstract
Due to heavy discharge of textile, steel and paper industries into nearby river
water directly with partial treatment, the contamination in river water is a big
concern day by day. One of the bulk contaminating elements found in river and ground
water is sulphate which has a long listed hazardous impact on the health of human
and living bodies. The bulk amount of gypsum released from plants is big contributor
for sulphate level up in water bodies. In this research, Rushikulya River, which
is a most well-known river in Odisha, is selected for study. The river water sample
was collected from ten different sites along this river.
The samples were analysed in laboratory and sulphate found was attempted to remove
on treating with a natural composite matrix prepared from bagasse waste and coir
pith. It is found that with the medium acidic range from 5 to 6 and with a dose
of 4:6 ratio composite matrix, it is possible to remove sulphate up to 97% from
the water sample taken.
