7、0 m3/day (100% domestic source) :The solution includes the following Scope:Separate pre-treatment system for domestic wastewater and tannery wastewater.Biological treatment process for treatment combined pre-treated tannery wastewater and biological wastewater.Tertiary treatment and disinfection by

8、UV in order to reach the treated water characteristics given above.Separate sludge treatment process for sludge generated from tannery wastewater and domestic wastewater.For treatment of sludge generated from domestic wastewater; we are proposing Mesophilic Sludge Digestion for reducing and stabiliz

9、ing the sludge produced, Cogeneration in order to generate power and thermal energy making sludge a tremendous Value on the way to sustainable development.Odor treatment for Zero Nuisance to the local population living near the WWTP.Notes : The sizing and design for mesophilic digestion system and a
