The optimization of energy consumption in sanitary treatment Package of 20&21th phases of Pars Oil & Gas Company (POGC)

Aeration accounts for 30% to 75% of the total energy consumption in activated sludge processes (ASPs).This paper mainly discussed the economic cost and energy saving of two different aeration systems in 20 &21 phases of Pars Oil and Gas Company WWTP. Results show that the total cost of the aeration unit is reduced obviously and the reason of this phenomenon is that the fine bubble diffuser system has less price and energy consumption. The cost analysis of the new aeration system is also compared with Isfahan WWTP as a large scale plant and has high compatibility. Conclusions were got that 2432 $ can be saved each year after replace the surface aerator with disc diffusers. Furthermore, this replacement can recovery its cost after 5.7 year
