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
