Anode rod for Chlorine?

Larry Weingarten

... want to put the anode in the center of the copper coil to get even current distribution. The anode could be plain steel (connected as Larry C says) though it might make the gray water grayer ;~) Can we assume the tank is plastic?

Anode rod for chlorine?

A metallurgist told me that an anode rod would protect the copper coil in my grey water tank, from the chlorine tablets I am going to add to the tank. Any thoughts on this? Thanks, Bob Gagnon

Sacrificial anode

It would be just like the zinc for saltwater engines. It has to be in electrical contact with the copper.

The tank is fiberglass

and I was thinking of putting 2 anode rods in, one on each side of the coil. Can I ground the anode rods to the coil above the water line outside of the tank? Thanks, Bob Gagnon

Continuity...

... is all you need. Making the connection where it can stay dry is good!

Dumb question?

Why not use PVC-coated copper like we purchase for propane or oil lines?

PVC coating

wouldn't that cut way down on the heat transfer? Bob Gagnon

Or add the chlorine after

it leaves the tank.

How would you regulate the amount of chlorine with just tablets and an unknown or variable water draw from the tank?

Excessive chlorine may not be friendly to the copper.

I remember small chlorine injection pumps used for treating well water that ran with the well pumps. I think you would have a tighter control this way.

Does the gray water have chlorine added on the front end before it becomes "gray?" I wonder what the levels are as it sits in the tank?

What will the gray water be used for? Just flushing or showering, etc.

I saw some pretty neat "systems" for treating rain water collection tanks in Germany.

I'm using the grey water

just for flushing. The local Culligan water guy told me that a slow dissolve chlorine tablet with dye would kill 100% of the bacteria in the tank, and last for about 8 weeks. It seems easier than a drip or injection. A metallurigst told me the effects of the chlorine would be countered by the anode rods. Thanks for all your help,
