Water is the most essential element next to air for our survival. Most of the earth’s surface is covered by water. In that, 97% is salt water present in seas and oceans. 2% is in the form of ice. Only 1% is fresh water, which is useful to us. This fresh water is available as surface water and ground water. Waters collected from coach wash centre were taken to the laboratory and analysis was carried out by conducting various tests, to determine the difference in physical and chemical characteristics of the water sample. Railway coach wash water contains oil, grease, sand etc., and main chemical characteristic which is not suitable for gardening like pH, iron, nitrate, ammonia so we can reduce this parameters in ETP and reuse foe washing train coach and gardening purpose. The tests that are conducted for determining the different physical and chemical parameters include: Chemical Parameters: pH, Total Alkalinity as CaCo3, Total Hardness as CaCo3, Calcium as Ca, Magnesium as Mg, Sodium as Na, Potassium as K, Iron as Fe, Oil & Greases, Free Ammonia, Nitrite as No2, Nitrate as No3, Chloride as CI, Sulphate as SO4, Phosphate as PO4, C.O.D, C.O.D. By doing water treatment for Railway coach wash water by ETP we can reduce the main chemical characteristics in the inlet water collated form collection tank. Main characteristics for reuse the water for washing coach like C.O.D,B.O.D, Turbidity, Oil and grease removal are reduce up to 88% to 95%.And also satisfy acceptable range for watering plants like pH, Alkalinity, Nitrate, Iron, and Ammonia are reduced. After the water is treated outlet water satisfy the acceptable range for gardening. Ammonia content in water is very important presents of high level of ammonia spoil the plants.
