ASSESSMENT OF DAIRY WASTE TREATMENT BASED ON SLUDGE VOLUME INDEX TECHNIQUE

Unscientific and Improperly treated sewage and industrial waste disposals causes environmental pollution. New technologies for modernity and change in life style of humans attribute new industries for their easiness and comfortability on one side which results in highly complicated and dangerous waste generation on the other side. Present study deals with the industrial waste treatment. Dairy industry is one among the highly objectionable waste producing sectors which increases the pollution rate of the total environment. Dairy industry consumes 2.5 to 4 litres of water per litre of milk process which comes out as waste water. Various studies revealed that dairy waste water is diluted milk and it contains BOD, COD, TSS, Oil & Grease and sometimes pH. So, treatment of dairy waste need special attention and adequate care is to be given before its final discharge to water bodies or to land. This work is an assessment of the performance of few dairies based on Sludge Volume Index whichhas been discussed and further scope of research area has been identified
