On an average, the total water requirement is 85 m 3 /k of RS plus about 50 m 3 /dayof soft treated water. For a distillery of 5,000 kL per annum capacity this will work out toabout 90 m 3 /kL of RS produced. The basis of the figures is also mentioned in thefollowing table:Table 3-2: Process & Non-Process Application of Water for Molasses BasedDistilleriesUsem 3 of rectified spiritproduced (Range)AverageBasis & RemarksA.
