by Rami E. Cremesti BS, MS - Water Treatment Chemist/Consultant


Water treatment chemicals fall, in general, into one of the following categories:


A – Corrosion Inhibitors (Cathodic, anodic, galvanic, filmers)

B – Anti-Scalants/Dispersants (threshold inhibitors, sequestrants)

C – Anti and De-Foaming Compounds 

D – Heavy Metal Precipitators

E – Odor Control Agents

F – Oxygen Scavengers (sulfites, hydrazine, Carbohydrazide)

G – Organic Metal Filmers

H – Coagulants

I – Flocculants

J - Biocides (oxidizing and non-oxidizing)

- Chlorine, hyprochlorous acid and Bromine are common oxidizing biocides
- Hydrogen Peroxide (H2O2) & Silver (Ag) is another one

K - Cleaners (scale cleaners, grease cleaners, corrosion cleaners)

L – RO Membrane Chemicals (Anti-scalants and cleaners)

M – Chelating agents

N – Tracer chemicals (used to detect leaks in water systems)

O – Analytical reagents
