CATALYTIC CARBON · CHLORAMINE
Design chloramine reduction around flow and contact time.
Chloramine is not simply a higher chlorine-capacity target. Media chemistry, water conditions, geometry, flow and service-life endpoint need to be defined together.
OEMQUICK ANSWER
PureRing Water supports catalytic carbon block development for OEM chloramine-reduction projects. Final claims require model-specific testing and the appropriate certification route.
Chlorine and chloramine are different design problems
Municipal systems may use free chlorine or chloramine. A standard chlorine-oriented carbon block should not be assumed to deliver the same chloramine kinetics. Confirm the disinfectant, inlet concentration, pH, temperature and target endpoint before choosing media.
The specification starts with the system
Rated flow and available pressure determine contact time and acceptable restriction. Cartridge length, diameter, wall thickness, core size and upstream sediment load all affect the practical result.
- Target flow and pressure-drop limit
- Challenge concentration and water chemistry
- Required capacity or replacement interval
- Housing and bypass-control details
How to benchmark a catalytic block
Run the candidate and incumbent filter with the same housing, challenge water, flow, sampling schedule and endpoint. Record a full breakthrough curve together with pressure drop and flush behavior instead of comparing one headline number.
- Initial and life-cycle pressure drop
- Chloramine concentration through the test
- Treated volume at the agreed endpoint
- Repeatability across more than one batch
Where chloramine projects appear
Typical project directions include foodservice beverage systems, water coolers, premium under-sink units and selected commercial point-of-use equipment. The correct block depends on the complete system and local water conditions.
FREQUENTLY ASKED QUESTIONS
Questions buyers ask before sampling.
Can a standard CTO block reduce chloramine?
Some carbon may reduce chloramine to a degree, but performance should not be assumed. A project needs defined water conditions, flow, capacity target and test evidence.
What information is needed for a chloramine sample?
Provide the housing, dimensions, rated flow, available pressure, inlet chloramine, pH, temperature, desired endpoint and service-life target.
Is catalytic carbon the only design variable?
No. Media chemistry is central, but particle profile, density, wall thickness, flow path and contact time also affect finished-filter performance.
Can the website claim NSF chloramine reduction for every model?
No. Any certification statement must match the exact listed model, standard, flow, capacity, manufacturing scope and current official listing.
