NSF 60 certificate 10% sodium hypochlorite plant for chlorine gas production

Brief Introduction:

Considered Inherently Safe Technology (IST), Klorigen™ provides a safe and efficient alternative to traditional pressurized chlorine gas offers a lower cost option to commercial bulk-delivered sodium hypochlorite. This technology allows users to generate on-demand at the point of use, eliminating any possibility of hazardous gas release.

Klorigen™ generators uniquely combine brine electrolysis with advanced membrane technology to deliver chlorine gas under a vacuum as well as co-product sodium hydroxide (caustic soda) available for pH elevation. Alternatively, the chlorine and sodium hydroxide products can be combined within the process to produce sodium hypochlorite at concentrations up to 15% (150 g/L).

Driving forces for on-site hypo production

• Safety
- Reduce or eliminate truck traffic and large quantity storage of hazardous chemical
- Consistent with efforts to eliminate stored chlorine

• Good Community Relations
- No off-site consequences
- No worst case emergency planning
- Reduced threat from accidents or terrorismSecure, Low Cost Raw Material Supply
- Salt instead of chlorine and caustic soda
- Stable pricing

• Reduced Cost to the City
- On-site high-strength generation costs less than bulk delivered chemical

• Solution Flexibility
- Hypo can be generated in one central facility or in distributed modular plants
- Generation can be by City personnel or private sector contract
- Various capital cost recovery options available

• On-Demand Facilitates “Steady-State” Process
- Hypo is always pure, and similar concentration

KLORIGEN™ development

• Operating concept based on conventional chlor-alkali membrane cell process technology, as used by major chlor-alkali companies today

• Process very similar to large scale chlor-alkali plants that typically produce in excess of 1000 tons of chlorine per day

• Equipment re-engineered by ETC for commercial and water utility markets using NSF-certified materials, robust membranes and advanced electrode technology (DSA) for on-site applications

Generation cost (Klorigen 0.32 usd/pound)
