Removal of Chloramine with Catalytic Granular Activated Carbon

Removal of Chloramine with Catalytic Granular Activated Carbon

Removal of Chloramine 

Many water utilities across the country are transitioning to chloramine for disinfection as an alternative to chlorine. This change is in response to stricter regulations on disinfection byproducts (DBPs), which are created when chlorine reacts with organics in water. Chloramine, a combination of chlorine and ammonia, is more stable and does not create DPBs.

Removing chloramine at the point of use, however, is more difficult than removing chlorine. Standard granular activated carbon (GAC) and carbon block products have limited capacity for chloramine reduction. Products known as “catalytic” or “surface-modified” activated carbon can provide a solution.

In general, the catalytic properties of carbon are measured by the rate at which carbon decomposes hydrogen peroxide. The resulting peroxide number, measured in minutes, estimates the carbon’s utility in any catalytic application, including chloramine reduction. Based on the comparative results obtained for different mesh size commercial carbons, the efficiency of chloramine reduction is discussed in the terms of peroxide decomposition capacity and further extended to the total life (volume) claims for corresponding GAC cartridge and carbon block. 

Pentek ChlorPlus-1 micron Chloramine Reduction Filter Specifications:

The Pentek ChlorPlus offers multiple product solutions for chloramine reduction. Chloramine is increasingly becoming more common as an alternative to chlorine for water treatment. 
The ChlorPlus carbon block cartridges help reduce sediment while providing greater chloramine performance capacities than granular carbon. They also significantly reduce the carbon fines found in many granular canisters. It utilizes advanced activated carbon technology which allows excellent chloramine reduction as well as superior chlorine reduction.
