Analysis of Physical and Chemical Parameters of Textile Waste Water

Abstract

Sample was collected from Textile Industry and analyzed for various physical and chemical parameters such as pH, total dissolved
solids (TDS), biochemical oxygen demand (BOD) and chemical oxygen demand (COD), Suspended Solids (SS), oil and grease, calcium,
magnesium, iron, manganese, sodium, potassium, total hardness etc. Results indicated that textile wastewater is basic. BOD and COD levels are high. TDS and SS levels exceed the permissible limits. Irrigation with  high TDS water will result in decrease in optimal crop production. Sodium levels are quite high in textile effluent, if soil is irrigated; soil  becomes poorly drained and tends to crust. Textile waste water was found to be very hard. Chloride and Sulphate levels are high. Some methods like Electro-dialysis, ion exchange method, biochemical purification etc. can be employed for the treatment of such wastewater
