Removal of Chloride, Hardness & TDS from Water Using Different Adsorbents

Abstract

Effective removal of Chloride, Hardness, and TDS (Total Dissolved Solids) from water has gained immense importance these days because these are at a high level in the water. Adsorbents i.e. Activated carbon is one of the most effective media for removal of these contaminants from water. Therefore, in our study we have used Adsorbent i.e. Activated carbon; Neem leaves powder, Coconut shell powder, and Charcoal powder which proved the effective removal of Chloride 250 mg/l (59.52%) from 420 mg/l, Hardness 557 mg/l (62.58%) from 890 mg/l, and TDS 1787 mg/l (67.9%) from 2632 mg/l from the water. We have collected the water sample for our study from Bore well near A. B. Road & Gole ka mandir in "Gwalior" city exceed the safe permissible limit for Chloride, Hardness, and TDS in water. The main objective of our study is to find the removal efficiency of all three Adsorbents i.e. Activated carbons with respect to chloride, Hardness, & TDS. The removal efficiency of each adsorbent is conducted over batch study, which includes the effect of various doses, contact time, the effect of initial concentration at normal pH and room temperature.
