Water and Wastewater Disinfection

Water and Wastewater Disinfeciton

Electrolytic Technologies can help you with all your water and wastewater disinfection applications. Traditionally, water utilities have used chlorine gas as the disinfectant of choice in their water treatment plants. However, recent publicly reported chlorine leakages and foreign terrorist attacks have raised concern regarding the safety of this practice.


Although some progressive public utilities are evaluating alternative technologies to pressurized chlorine gas, chlorine remains the most effective broadband disinfectant. In response to this preference, Klorigen™ on-site chlorine gas generators can facilitate the continuation of current disinfection methods while promoting safe practices through the use of chlorine gas at ambient pressure.


Alternatively, water disinfection may be safely and effectively accomplished using Klorigen™ on-site generation of high strength sodium hypochlorite solution. Storage of 12.5% concentration requires less than one-fifteenth of that needed for low strength (i.e. less than 0.8%) generated sodium hypochlorite.


Klorigen systems are ideally suited for wash disinfection. The generated bleach is chemically ultra-pure, and at 10 – 15% concentration, unlike commercial bulk deliveries which have undergo constant degradation between the production and use.

Benefits of Klorigen™

  • Systems chlorine gas at less than atmospheric pressure, virtually eliminating the possibility of a dangerous toxic gas release.
  • The generated chlorine gas can be combined with co-product sodium hydroxide within the process to produce high-strength sodium hypochlorite at an operating cost that is in most cases is comparable to or less than any alternative chlor-alkali product available to the end user.
  • Klorigen™ systems have a projected lifespan exceeding 20 years with minor refurbishments scheduled at five to eight-year intervals.
  • The generated chemical products (elemental chlorine gas, sodium hydroxide and sodium hypochlorite) are equal if not superior in quality and efficacy to conventional bulk-supplied alternatives and comply with National Sanitation Foundation (NSF) standards (USA).
  • Modular designs allow for the capacity of a system to be increased within its existing footprint by a factor of two or even three in less than one week with minimal interruption to operations.
  • Every system and subsystem is designed to fit within conventional ocean-freight shipping (TEU) containers, allowing for low cost road and sea freight to the customer’s site.
  • By design, the system operates at less than one atmosphere of pressure with electrodes separated by a semi-perfluorinated membrane, eliminating any risk for hydrogen explosion in either the electrolyzers or downstream in the product storage tanks.
