What is Water Quality Parameters?
Water Quality Parameters:
No single parameter is possible to determine the quality of water. Depending on the use for which water is intended to be used, it should have the right parameter. For example, if water is to be used for washing purposes (laundry etc.), it should be ascertaind that it is not hard. Hard water is also harmful for use in boilers etc., as it leads to scale formation. For drinking purposes, water must be pure and free of any pollutants. Figure given standards for industrial and drinking (human consumption by BIS).
The quality of water is basically judged by three parameters, viz. Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD). However, some other parameters (given below) are also useful for determining the quality of water:
- Most Probable Number (MPN)
- Total Solids
- Silica content
Content of chloride, sulphate, phosphate, nitrate and microorganisms.
