GAC and Chloramines and other questions

[barebottoms]

Hi Randy,

I re read your Chloramine article and it left me wondering about a few things.

With so many different types of GAC media out there, what type was used for your article? Mesh? ie was it the cheaper Coco GAC or Bituminous coal type?

How big of a contact area did the water go through to be "effective" at removing Chloramines in the water? Was it just the standard "1 stage" (10 x 2.5)

At which point in RO processing was the test deemed "effective"? Was there testing right after the GAC, right after the Membrane?

What is the impact of having Ammonia and Chlorine ions? Will there be free Chlorine ions after the GAC stage? What are their impacts to the membrane?

Thanks!
