Belmar Technologies is the exclusive UK distributor for the full range of UV Water Disinfection systems designed and manufactured in Germany by Enviolet GmbH.

There are numerous suppliers of flow through UV Disinfection equipment. Microspear® technology is superior and invaluable in controlling bacteria and fungal contamination providing a reliable solution for maintaining sterile water in process tanks, rinses and process machinery after the initial disinfection. 

Enviolet Microspear®In Tank UV Disinfection Technology

Microspear® is applied in open rinses and tanks used to disinfect the water and to disinfect of machinery and parts.

The application usually is designed in cooperation with Enviolet to get the best results. In doing so, we may prevent carrying problems into subsequent steps of the process.

Also, this will improve the functioning of the machinery as germs will not impair parts of the machinery such as pumping stations, storage tanks or plating equipment.

The best applications are to be found in rinsing processes and in the hygienic storage of water and aqueous solutions.




Disinfection of open tanks and rinses for suppression of microbiological growth

Electrical Safety

Enviolet is the only supplier that equips submerged disinfection devices like Microspear® and Microfloat® with an Internal Earth for the built-in ground fauIt interlock. This is the only way we can ensure that the devices stay electrically safe in the event of a breakage of the unit when submerged .

Microfloat® units maintain sterile headspace and disinfect tank walls as the liquid level changes. Combined with fixed Microspear® units the process tank becomes a long resonance time UV reactor.

UV Tank Disinfection Microfloat®

Microfloat® is the only floating UV-disinfection system for tanks. Microfloat® disinfects not only the complete internal space of the tank (water and atmosphere), but also prevents regrowth and reinfection of the damp tank walls. The Two-in-One solution offers safe disinfection and can be retrofitted into an existing tank with little or no disruption.

Low energy UV installations for  existing tanks is a standard applications for Belmar.

Microfloat® for tank disinfection system is ideal for tanks with static and varying filling levels.

Typical fields of application:

  • Climatic chambers (scrubbers and humidifiers)
  • Cooling towers (suppression of legionella)
  • Food and beverage
  • Pharmaceutical
  • Chemical industry
  • Metal Finishing
  • Drinking water storage

How it Works

Ultraviolet (UV) disinfection of wastewater is a completely chemical-free process and uses the natural process of ultraviolet germicidal irradiation (UVGI). This process uses short-wavelength ultraviolet (UV-C) light to kill or inactivate microorganisms by destroying nucleic acids and disturbing their DNA, leaving them unable to perform critical cellular functions.

The ultraviolet UV-C disinfection process is able to kill 99,9% of the microorganisms like viruses, bacteria, algae, yeasts, mold… including Legionella and Cryptosporidium.

Disinfection of Cooling Towers – Suppression of Legionella

The growth of microorganisms ( Such as legionella ) in the cooling circuit is effectively suppressed by Ultraviolet radiation and ensures safe and stable operation of the cooling tower.

The integration of UV technology in the largest buffer volume (usually the operating basin of the evaporation cooler ) coverts the basin into a large “UV Reactor”. Most of the circulating water volume is permanently under UV-C radiation. Organisms are rendered inactive due to the relatively high residence times and extremely high UV dose that can be applied into the cooling water compared to flow through UV systems. If necessary equipment that cannot be reached directly by ultraviolet radiation can be disinfected by occasional low level peroxide dosing. Hydrogen peroxide decomposes without residue under UV radiation and causes no corrosion as found with bromination systems.

● No development of microbiological resistance to biocides

● Low operating cost ( Less chemistry and monitoring )

● Little maintenance involved
