ABSTRACT:
The study on Physicoochemical analysis of the effluent of woolen carpet (Namada) industry was conducted at Tonk which is located in north-eastern part of the Rajasthan state between 75°07' to 76°19' east longitude and 25°41' to 26°34' north latitude. Aim of the study was to carry out a detailed physico-chemical analysis of the effluents of four selected active carpet manufacturing units along with their remedial measures. In the physicochemical analysis of the effluents, all the waste water parameters viz., color, odour, temperature, pH, BOD, COD, TDS, conductivity, acidity, chloride, and hardness, Calcium, Magnesium and Nitrate were analyzed. Colour of the four analyzed effluents ranged from dark red to greyish-black and had fishy to pungent smell. Temperature of the samples ranged between 280C—520C .Besides this, all the effluents were of acidic nature and their pH value ranged 3.4 – 4.3. BOD ranged between 290 – 850 mgl—1. COD of all the 4 samples ranged 1043 – 1889 mg / l—1, TDS ranged from 1005 mg / l to 1472 mg / l. The conductivity or electrical conductivity (EC) varied in the range between 1252 – 2209 µmho/cm. The Acidity of all the effluents ranged from 371 mg/l – 404 mg/l. Chloride (Cl—) ion concentration was in the range of 1995 mg/l – 2210 mg/l, total hardness varied from 2821 mg/l to 3550 mg/l. Nitrate content in the collected samples ranged between 123 mg/l – 342 mg/l.
