Electrolyser system for water disinfection

The Siemens Industry Automation Division has added four tubular cell electrolyser systems to its water disinfection portfolio. The new Osec B-Pak™products have an enhanced, compact construction and a newly designed electrolyser cell. This systems from Siemens generates a 0.8 percent sodium hypochlorite solution from water and salt for disinfecting drinking, process and swimming pool water.

Available in four new capacities, Osec B-Pak tubular cell electrolyzer systems from the Siemens Industry Automation Division extend the output range of the company's water disinfection portfolio. The largest model, the OSEC B-Pak 260 system, can produce up to five kilograms of chlorine per hour or 120 kilograms of chlorine per day. Producing the sodium hypochlorite as-needed and on-site eliminates the dangers involved in storing and transporting chlorine gas or commercially available sodium hypochlorite solution. As it is also cheaper to operate an OSEC B-Pak system than to buy sodium hypochlorite, the initial capital cost pays off quickly.

The newly developed systems are compact and mounted on a skid to save space, easy to operate, and designed for a long service life. The core component is a newly designed, especially robust electrolyzer cell in a clear acrylic enclosure that produces a stable disinfectant solution. The low-concentration solution minimizes corrosion and degradation - loss of available chlorine during storage - which occurs with highly concentrated solutions containing 10 to 15 percent sodium hypochlorite. Operational safety is enhanced thanks to the fully automated control system. Components are readily accessible and easy to clean. The systems are supplied completely pre-assembled, electrically connected and tested, and can be quickly installed and commissioned on-site.
