STUDIES ON PHYSICO CHEMICAL CHARACTERISTICS OF THE MOLASSES EFFLUENT

S. GERSHOME DANIEL RAJADURAI AND S. DAWOOD SHARIEF*

Abstract

Molasses is a viscous by product of the processing of sugar cane or sugar beet in to sugar. For the present study, the effluent samples were collected from lactic acid manufacture unit using molasses as a raw material at SIDCO industrial estate, Thiruvallur, Chennai. The physico chemical parameters of the effluent viz, colour, odour, pH and EC, were determined following the methods of APHA (2005). Salinity, Dissolved oxygen (DO), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Suspended solids (TSS), Total Dissolved solids (TDS), Hardness, Bicarbonates, Alkalinity, Chloride, Nitrites, Calcium, Sulphate, Sodium, Potassium, Magnesium and Total free sugars (Glucose) of both the effluents (untreated and industry treated) were also studied following standard methods. Parameters mentioned earlier were studied immediately after collection of the effluent.
