Corrosive Environments

UV Disinfection for Corrosive WaterUV disinfection is well regarded worldwide for the effective chemical free disinfection of water. Highly corrosive environments such as seawater and industrial waters containing organic solvents, acids and alkalis can now be cost effectively treated with UV thanks to the polypropylene range of UV disinfection systems manufactured by UltraAqua. Polypropylene options are available in the closed reactor (barrel style), open channel and reservoir suitable systems.

UltraAqua's polypropylene (PP) UV disinfection systems are completely corrosion resistant and ideal not only for sea water and aquaculture, they also have a very high chemical resistance. They are resistant to organic solvent as well as acids and alkalis. Polypropylene has a design stress of 1,000 psi at 22.7 ºC and is excellent for laboratory and industrial drainage pipes where mixtures of acids, bases and solvents are involved.

UltraAqua Corrosion Resistant UV Disinfection System (Closed Reactor)

ULTRAAQUA’s polypropylene (PP) closed reactor series offers very high quality at a reasonable price. They are extremely versatile due to their corrosion-resistant construction and a flow range from 5 to 1000 m3/h. As a result of attractive price/performance ratio and excellent long term experiences many customers select PP reactor based systems also for fluids that are non-corrosive. The major benefits are:

  • Rigid, corrosion-resistant construction from DIN 8061/62 industrial grade polypropylene for very harsh environments
  • Simple installation, simple operation and maintenance
  • Available with standard or advanced control cabinets
  • Optional UV monitoring with digital UV Önorm approved sensors
  • Available with DIN or ANSI flanges
  • No tools needed for scheduled maintenance

Considerations When Choosing a Polypropylene or Stainless Steel UV System

UltraAqua UV systems based on polypropylene (PP) material are completely corrosion resistant. They can be used in all water salinities at temperatures up 80 ºC. However, please note that the UltraAqua range of stainless steel UV reactors are made of high grade AISI316L steel which has been passivated and electropolished internally as well as externally. Corrosion resistance is very high for these as well. As a rule of thumb choose polypropylene (PP) reactors if sea water temperatures exceed 25 ºC.


UltraAqua also delivers UV systems with customised connection sizes and/ or orientation of connections (L, Z or angled configuration). It is also possible to combine control panels for installations where multiple UV reactors operate simultaneously.

  • Cost effective
  • For flows up to 68M3/h 
  • Ideal for small flows in industrial applications
  • Compact design
  • Easy setup
  • Carbon fibre reinforced plastic (CFRP) cabinet that is air and water tight up to IP66 ensuring a dry, safe environment for the electrical components.


Multi-Lamp For Corrosive Environments (Closed System)

  • Extreme versatility and quality for a very reasonable price
  • Corrosion resistant construction for very harsh environments
  • Simple installation, operation and maintenance
  • No tools needed for scheduled maintenance
  • Uses Ultratherm lamps with 16,000h guaranteed lifetime
  • Available with standard or advanced control cabinets
  • Option UV monitoring with digital UV Önorm approved sensors
  • Available with Din or ANSI flanges
  • Internal digital temperature sensor mounted in titanium housing


ACN Series for Low UVT Fluids (Closed Systems)

  • Designed for high turbidity water applications.
  • Suitable for high risk applications such as hospitals, biotech, ultra pure water applications
  • A more compact design reduces the distance between lamps and eliminates "dark areas" resulting from low UVT.
  • Meets the high demands for intake water for aquaculture (as defined by the Norwegian Veterinary Institute)

Polypropylene systems are also available for use in open channels and reservoirs.

Closed reactor UV systems are also available in Stainless Steel.
