ASSESSMENT OF VARIOUS PHYSICO–CHEMICAL PARAMETERS OF TREATED AND UNTREATED WASTE WATER FROM DISTRICT FATEHGARH SAHIB, PUNJAB, INDIAVIKAS PAHAL, RUCHIKA RANA, GURDYAL SINGH AND KRISHAN SAWROOP DADHICHAbstract Direct release of improper and untreated wastes in various water bodies deteriorates its quality,which makes it unsuitable for drinking and other economic activities. Study of various physico chemical parameters of water will create primary data which is essential for effective and specific treatment methods to recuperate our water resources. In the present study, various physico chemical parameters like total dissolved solids, total suspended solids, total alkalinity, Cl-, SO4-2,Na/K ions, total hardness, different forms of nitrogen (nitrites, nitrates, ammonical nitrogen) and phosphorous (total phosphate, total ortho phosphate, acid hydrolysable phosphate), carbonate/bicarbonate, BOD and COD of treated and untreated waste water was studied. As per Bureau of Indian standards, values of certain physico-chemical parameters were found to be substantially higher than the permissible limits in untreated waste water in comparison to treated one. BOD,COD, TDS, TH, chloride and ammonical nitrogen values showed strong positive correlation with each others. |
