The two principles of disinfection
There are two principals of disinfection: primary disinfection achieves the desired level of mircroorganism kill or inactivation, while secondary disinfection provides enhanced protection by preventing the regrowth of microorganisms harmful to human health between incoming public water supply to your building and the water distribution system inside your building right up to point of use – tap, shower etc.
Choosing the optimal solution
Deciding which technology or generation system is right for you hinges on your objective, application, water usage, flowrates, preference and tolerance of generation method as well as other criteria.
Selecting between some of the most common technologies such as traditional Sodium Hypochlorite, Chlorination and Hypochlorous Acid Generation, Chlorine Dioxide Generation, Ozonation, Ulraviolet Light (UV), Ultralox40®... requires specialist advice and in all likelihood a combination of technologies may be more suited tailored entirely to your site / building / water distribution system.
The eBook (free download) is an introductory reference tool that helps you compare some of the most common disinfection techniques:
Traditional Sodium Hypochlorite
Sodium Hypochlorite (NaOCI) is one of the most commonly used compounds for water purification, especially across large scale surface purification, bleaching, odour removal and water disinfection in cooling towers for example.
Chlorination (Hypochlorous Acid Generation)
The GENOX generator produces a colourless liquid which is generated on-site, on-demand without buying, mixing or handling toxic chemicals. Direct electrolysis of brine, creates an oxidant NEUTHOX® on demand.
Chlorine Dioxide (new style Catalytic Generation) or ClO2IX
A universally effective primary and secondary disinfectant without the usual limitations of chemical mixing, handling or storage.
Chlorine Dioxide – WRAS Approved Pureox 3500
A universally effective primary and secondary disinfectant, generated using a patented Safe Generation per Batch (SGB) technology.
Ozonation is a water treatment process that destroys microorganisms and degrades organic pollutants through the infusion of ozone, a gas produced by subjecting oxygen molecules to high electrical voltage.
Ultraviolet Light (UV)
Ultraviolet (UV) radiation is generated by a special lamp. When it penetrates the cell wall of an organism, the cell’s genetic material is disrupted and the cell is unable to reproduce.
A Regulated, stable, highly effective low concentration form of chlorine and particularly efficacious fast-acting biocide.
