Dear STP operators. It is ideal to have 400km..bore area sqm..flow velocity m/s ..  The above data gives the derail of primary 1st stage treatment.. with HRT = ... 4 days.. This would generate sewage gas duly vented and used. Next STP can be evolved as Anaerobic with media filteration in the wwt plant. can be secondary treatment. Ideally could have 4 days HRT for ideal benefits. Tertiary process follows next, aerobic for 2-3 days HRT...  Can the above be followed or with adaptation .. Well wishes.
