Why Chlorine Dioxide?

Water treatment to prevent the proliferation of legionellosis bacteria is one of the main challenges with regard to hot water recirculation networks in water-sanitary systems.  In this field the use of chlorine dioxide (ClO2) has replaced that of chlorine (hypochlorous acid) for water treatment and disinfection because of the many advantages brought by a higher biocidal and antiviral power, as well as being independent of the pH of the water to treat.

In particular, chlorine dioxide is the safest and the most effective answer against the risk of legionellosis, especially in cooling towers and Hot Water Systems, by affecting and breaking down pathogens and the biofilm, (a bacterial aggregation that is the natural habitat in which both Legionella bacteria, the cause of legionellosis, and other species of bacteria proliferate).  Using chlorine dioxide in disinfection of water has demonstrated to be no less than 10 times more effective against bacteria, algae, fungi and viruses.

Chlorine dioxide is not aggressive toward pipes and its effect is longer-lasting, up to several days, and over a wider area from the injection point, ensuring the treatment of a whole plumbing system, even by using a small amount of product. It is commonly used as a ‘dispersive’ treatment which means the chlorine dioxide is dosed into the water system and travels around the entire water system. This ensures a ‘residual’ level of CLO2 which can continue to kill bacteria in all areas of the system that it reaches and not just at the point of use.

Aqua Products offer a wide range of LOTUS chlorine dioxide generators from EMEC as below.  For more information please contact us.

LOTUS “Easy” Generators

LOTUS “Easy” system produces, doses and controls chlorine dioxide for water disinfection.  Chlorine dioxide is produced from diluted base chemicals: acid-chlorite process from hydrochloric acid and sodium chlorite.  Chlorine dioxide produced by LOTUS EASY is set to be proportional to the circulating water flow.  There is no storage of chlorine dioxide hence no chlorine dioxide gas or concentrated solutions exist outside of process application.

  • 8 to 80 g/h
  • instantaneous production
  • level alarms
  • water meter input
  • proportional dosing

LOTUS “Mini” and LOTUS “Maxi” CLO2 Generators

LOTUS “Mini” system produces, doses and controls chlorine dioxide for water disinfection.  Chlorine dioxide is produced from diluted base chemicals: acid-chlorite process from hydrochloric acid and sodium chlorite.  Chlorine dioxide produced by LOTUS Mini (and Maxi) is set to be proportional to the circulating water flow.

  • Lotus Mini 8-80 g/h
  • Lotus Maxi 80-1000 g/h
  • Gas sensor option
  • Available with ethernet, GSM, Modbus or Wifi option
  • CL02 or redox probe models for LOTUS Mini

LOTUS AIR Chlorine Dioxide Generator

The Lotus Air system produces, doses and controls chlorine dioxide for water disinfection in a BATCH process.  Chlorine dioxide produced by LOTUS AIR is stored in a tank and dosed proportionately to flow on demand.

  • 10-60g/h
  • Gas sensor option
  • Available with ethernet, GSM, Modbus or Wifi options
  • ERMES communication
  • CL02 or redox probe models available
