Industrial Applications
Municipal Water Disinfection
Primary disinfectant for drinking water treatment plants — sodium hypochlorite is dosed to achieve a free chlorine residual that inactivates bacteria, viruses, and protozoa throughout the distribution system. NSF/ANSI 60 certified grades required.
Wastewater Treatment
Disinfection of secondary and tertiary treated effluent before discharge. Sodium hypochlorite is also used for odor control in collection systems and for disinfecting biosolids.
Cooling Tower Biocide
Oxidizing biocide for controlling Legionella, algae, and biofilm in cooling water systems. Typically dosed as part of a rotating biocide program alongside non-oxidizing biocides.
Food & Beverage Sanitation
CIP (clean-in-place) sanitizer for food processing equipment, tanks, and pipelines. Food-grade concentrations (50–200 ppm free chlorine) are used for surface sanitation and equipment sterilization.
Industrial Bleaching
Bleaching agent for pulp and paper, textiles, and laundry operations. Sodium hypochlorite oxidizes chromophores in cellulose and synthetic fibers, removing color and stains.
Swimming Pool & Recreational Water
Sanitizer for commercial pools, water parks, and recreational water facilities. Liquid sodium hypochlorite is preferred over solid chlorine for large-volume applications due to ease of handling and dosing.

Other Water Treatment Products
Sodium Hypochlorite vs. Alternatives
Sodium hypochlorite (liquid bleach) is the most widely used disinfectant in water treatment. Here's how it compares to alternative chlorine sources.
| Attribute | Sodium Hypochlorite | Calcium Hypochlorite | Chlorine Gas |
|---|---|---|---|
| Available Chlorine | 10–15% (bulk), 5.25–8.25% (trade) | 65–70% available chlorine | 100% available chlorine |
| Form | Liquid — easy to dose with metering pumps | Solid — tablets or granules | Compressed gas — specialized equipment |
| Safety | Moderate — corrosive liquid, no gas release | Fire/explosion risk with organics | High — toxic gas, strict controls |
| Stability | Degrades over time — use within 60–90 days | Stable — years shelf life | Stable in cylinder |
| Cost | Low — commodity pricing | Moderate | Lowest per lb Cl2 — but handling cost |
