Water Source - effluent water

[tommorris]

Hi All...
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...:anyone::anyone:

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. :gah: 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.
2. If you are worried about legionella I would suggest never using PEX pipe. The HX is copper and copper has intrinsic antibacterial and antimicrobial properties.
3. If it is that bad why would some states and the Canadian government offer tax rebates for it?
4. It's double walled

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.



1. As would be all sewer piping. I was talking about the potable side of the exchanger.
2. If you are worried about legionella I would suggest never using PEX pipe. The HX is copper and copper has intrinsic antibacterial and antimicrobial properties. There is little risk of contamination with plastic pipe so long as the temps are kept where they need to be.
3. If it is that bad why would some states and the Canadian government offer tax rebates for it? Yeah, the government says it's OK so it must be safe right? :whistle:4. It's double walled

Agreed throw in a heat exchanger of your choice and go from there.

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!
