2.17 CHARACTERISTICS OF WASTE WATER
The waste water from sugar industry is nontoxic and non-hazardous in nature. Suitable in plant measures are adopted in the factory as enumerated elsewhere to reduce the quantity and contamination waste water. Oil traps are provided in the mill house to minimize the contamination of oil & grease in the waste water. Small sumps are provided at suitable location in the factory to receive the leakage of juice and syrup & also some quantities of effluent process equipment. The leakage of juice and syrup thus collected is recycled to process. Hot condensates obtained from evaporators are recycled to the process to meet the requirement of imbibaation etc., and also to meet the makeup water requirement for cooling tower, boilers etc.
2.18 EFFLUENT WATER TREATMENT
2.18.1 DATA
