water during adsorption as it reduced from 6HU to 2-2.7HU. This indicate an efficiency of 55-66% for colour removal. Turbidity follows the same tread of treatment as colour with 80-83% removal. The result shows a reduction efficiency of 63-72% for conductivity with 10% Zncl2 impregnation being the most effective. Total solids and Total Dissolved solid has removal efficiency of 45-55% with 20% impregnation being the most effective for Total solid removal.
