UV Disinfection

Unlike chemical approaches to water disinfection, UV light provides rapid, effective inactivation of microorganisms through a physical process. When bacteria, viruses and protozoa are exposed to the germicidal wavelengths of UV light, they are rendered incapable of reproducing and infecting. It has demonstrated efficacy against pathogenic organisms, including those responsible for cholera, polio, typhoid, hepatitis and other bacterial, viral and parasitic diseases.

UV-oxidation

UV light, in combination with hydrogen peroxide, destroys contaminants. UV converts hydrogen peroxide into highly reactive hydroxyl radicals. These hydroxyl radicals oxidize contaminants, breaking the bonds between the molecules, and reducing the potentially harmful chemical to its safe, elemental components.

UV-photolysis

UV-photolysis is a photochemical reaction that takes place when a contaminant molecule absorbs UV light. The photons break down and disrupt the chemical bonds of the molecule, and reduce the potentially harmful chemical to its safe, elemental components.

Chlorine/Chloramines Destruction

Chemical addition involves the introduction of an added substance and is therefore undesirable. As an alternative to the use of chemicals and activated carbon beds, UV technology can be utilized to destroy chlorine/chloramine, thereby eliminating the need for chemical handling and bacteria breeding.

Filtration

In its simplest form, filtration separates solids from fluids by utilizing a medium through which only fluid can pass. However, custom-designing and refining the entire filtration process will maximize solids separation, while reducing operating costs, maintenance intervals and physical footprint.

Ozone Destruction

In specific water treatment applications, ozone is applied to the water stream to oxidize trace organics or to disinfect the piping and distribution system, but residual ozone is often left behind. Adding UV energy to ozone catalyzes it into harmless oxygen.

TOC Reduction

Utilizing UV light in an 185nm wavelength enables the formation of free radicals, leading to the oxidation of organics into CO2 and H2O.
