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
