Major Issues with Raw Yamuna WaterMajor Issues with Raw Yamuna Water
Deteriorated Quality of Yamuna waterQ yNH3‐N as high as 40 TIMES against limit < 1 mg/lit.BOD as high as 12 TIMES against limit < 3 mg/lit.PRE‐CHLORINATON DEMAND as high as 134 mg/litPRE CHLORINATON DEMAND as high as 134 mg/lit.which is too high
Excessive chlorination is used to oxidize Ammonia Excessive chlorination is used to oxidize Ammonia which is carcinogenic (cause of Cancer)
