Mission Ganga Cleaning - Update.

Hello,

Central Govt has started a great intiative of Mission Clean Ganga. I would like to know more on the technology applied, methods used and systems employed to actually do the needful for cleaning Gnaga. Preventing dischaarge of industrial & domestic effluents is one of the tasck. 

Are we using any biological methods, or air diffusions or filteration. Would be great to get some update. 

My interest to this post is not commercial its purely acedamic.
