If you are running a wastewater plant why not using a digester, creating biogas that will run the generators to give you "free" power to run the whole system WTP and WWTP together. This is not new and is used in many countries.

Hi Jan Verwater - thanks for replying. Currently a number of our sites utilise Combined Heat and Power (CHP) technologies to produce electricity providing a solution to rising operational costs.

As far concern with domestic Sewage treatment, with any anaerobic process bio-gas can be generated but it has a limitation and which can not provide self sustained run of whole STP. It can hardly satisfy about 25 to 30% requirement if digesters are sucessfully operates.

Gas recovery is a good idea but it isn't cheap. DCWater has installed a Cambi system in their wastewater plant and it generates about 1/3 of their plant electricity needs. However, it cost upwards of 300 million USD.
