Water Source - effluent water
First time user here. Just wondering if anyone has any experience with water source HP using wastewater treatment plant effluent water as the water source. We would like to try using our NPW (non-potable water), but we have concerns with the low amounts of ammonia, nitrates, and ferric in the water and the effects it may have on the cupornickel (90/10) coils. Another option may be the brazed plate heat exchanger? Any and all comments will be welcomed...
Norway and Sweden
You could use these
I bought one for my house but no plumber is willing to give me the time of day so it sits in my basement doing nothing. At least I bought it when the US dollar was very strong against our nothern neighbors.
The plumber won't touch it because it's a haven for Legionella growth.
1. As would be all sewer piping.

3. If it is that bad why would some states and the Canadian government offer tax rebates for it?
4. It's double walled
Follow the link. Think before you post.
In the past we have used stainless steel heat exchangers.
I was referring to this link: http://www.renewability.com/power_pipe/index.html
Perhaps it is you who should be doing the thinking. Legionella will grow in potable water that is allowed to stand at 95-115 degrees F. Since that is about the temperature that the potable water would be in that heat exchanger, it would be an ideal condition to cultivate Legionella.

The POOPLOOP!! HAHAHAHAHAHAHA!!!
I pitched this idea to our city sewer dept. 14 years ago. It didn't go over as well as I thought it would. I still say there are millions of BTUs available in the flow at the sewer plant!
