Energy recovery in wastewater treatment plant
Energy recovery in wastewater treatment plant
(OP)
I've searched the forum regarding this topic, but the closest I could find is this thread633-211694: recovering energy from warm waste water, which is a closed thread. I'm hoping somebody could give me a hand here.
I'm working on a project where we would like to harvest the heat in the wastewater, and use the heat for a number of other purposes, such as providing heat for the building (heating and hot water use), the process. We would also like to use the heat for the cooling of the building.
I'd like to know what would be your approaches are to this project, and what type of equipment are you thinking of using.
Thank you.

Lots of "slightly warm water" is not a good source of energy for power production.
Sources of "high quality" heat is the best bet for power generation. (This is why proposed solar power plants concentrate sunlight onto a central collector)
Power generation at wastewater plants is typically done via low-btu IC engines burning 200-500 btu/cf waste digester gasses. CAT Cummins and others have many WW installations across the USA using these engines.

I suspect it wouldn't be cost effective.
