FIXED BED COLUMN STUDY FOR THE REMOVAL OF CHLORIDE FROM RAW WATER

The responsible for increase in freshwater demand is due to rapid growth of population, industrialization and modern agriculture practices. The aim of the study tends to carry out a column study for the removal of chloride from raw water. Raw water is natu ral water found in environment such as rainwater, groundwater and water from bodies like lakes and rivers. Water samples were collected from Valliar River, AVM Canal and Periyakulam Pond from kanyakumari district. Soil used for the study is loam soil. The raw water samples were allowed to pass through the vertical column of soil at different bed depth such as 15cm, 30cm, 45cm, and 60cm depth. The outflow of water is collected which is subjected to analysis the chloride concentration. It was found that when the depth of soil increases, the rate of filtration also increases. Therefore concentration of the chloride content is reducing linearly .
