Chloramine - check your water source!

[Buckeye Field Supply]

Hi folks - thanks for the heads up Myka!.

The key with chloramines is to provide adequate contact time with the carbon prefilters. In some situations, one good carbon block is sufficient. Our practice to to always include two carbon prefilters in systems used with chloramines.

Don't bother with a standard GAC cartridge.

Catalytic GAC is another story. It is a super fast acting GAC and we include this as the first of two carbon stages in our Chloramine Special RODI's. The CGAC cartridges are axial flow - meaning the water must flow through the length of the cartridge to maximize contact time. The second carbon block we use is a top of the line, 20,000 gallon, 0.5 mic block - the best we can find.

As mentioned previously in the thread, you will see relatively fasted DI depletion with waters containing chloramines. A dual stage DI is not a bad idea with these waters.
