Is there any CPCB/MoEF/State PCB standards available for disinfected sewage/ wastewater used for gardening & recycling purposes? I want to know the treatment limit for MPN value when wastewater is disinfected.
Also is there any understanding regarding the rate of bacteria removal while using chlorine & UV system to disinfect sewage / waste water?
We are one of the known developers in Mumbai using treated water for gardening & flushing purposes. We are selecting the best available in-house STP system for treating sewage and reusing for domestic use.
So far I found only secondary treatment standards on guidelines. Kindly advice.
