Sodium Hypochlorite Disinfection System
On-Site High-Concentration Sodium Hypochlorite Disinfection System for Water Treatment Plants
TECHWIN, in collaboration with Korea Water Resources Corporation, has developed Korea’s first on-site generation system utilizing membrane-based brine electrolysis to produce 12% high-concentration sodium hypochlorite, replacing conventional liquefied chlorine disinfection systems, commercially available sodium hypochlorite, and imported high-concentration hypochlorite generators.
Unlike foreign-manufactured systems, which are simply downsized versions of intermittent commercial hypochlorite generators, TECHWIN has innovated both the materials and structural design of its system. It has secured multiple domestic and international fundamental patents, obtained New Excellent Product (NEP) certification, and been recognized as a next-generation world-class product. Additionally, it has been officially designated as an innovative product by the Korean Public Procurement Service.
- Outstanding Cost Efficiency – Reduces operating costs by more than 50% compared to commercially available sodium hypochlorite.
- Operational Stability&Efficiency – Minimized storage requirements with real-time production and on-demand usage.
- Superior Sodium Hypochlorite Quality – Maintains Type 1 sodium hypochlorite, stable for approximately 15 days at 20ºC.
- •Minimal Installation Space – Reduces space requirements by 40% compared to foreign products.
