Studies on Physico-chemical Parameters and Concentration of Heavy Metals in Sugar Mill Effluent

Mohd. Aslam Saifi and H. B. Singh

The physico-chemical characteristics and heavy metal contents in the effluents discharged from Neoly sugar mill have been explored. The physico-chemical parameters such as colour, odour, temperature, pH, electrical conductivity, total dissolved solids, dissolved oxygen, COD, BOD, alkalinity, total hardness, Ca+2, Mg+2,sulphate, chloride, fluoride and concentration of heavy metals (like Cr, Mn, Ni, Zn, Cd, Fe, Cu, Pb and Hg) of the effluent collected from the various sites between the exit point at the mill and discharge point in a natural drain in different months have been determined.
