UV water treatment systems for marine water treatment - Water and Wastewater

As the market leader for the marine and shipping industry, we supply a number of key clients with a range of marine water treatment applications, including cruise liners, luxury pleasure craft, transport freighters and specialised FPSO (floating production, storage and off-loading) vessels around the world.

Our leading water treatment systems are compact in design, allowing for ease of installation into restricted spaces and provide protection against microorganisms, bacteria, and viruses without the use of chemicals. Our standard marine applications include:

  • Drinking water
  • Wastewater discharges – Alaska HB80
  • RO Membrane protection
  • RO feed water de-chlorination & disinfection
  • Swimming pools & water features
  • Aquaculture & well boats (fish farming)
  • Ballast Water Treatment (BWT)

Our UV Systems are sized to comply with the Alaskan HB80 wastewater discharge regulations. The regulations require that all cruise ships and large passenger/shipping vessels planning to discharge effluent wastewater into state waters, to first provide disinfection and treatment of the wastewater using a series of state-of-the-art wastewater treatment technology.

UV disinfection systems form the final stage treatment as part of the Alaska HB80 approved onboard advanced wastewater treatment package, and is used to eliminate harmful microorganisms before discharge.

The process of disinfecting water with UV light is a proven technology, and has been widely used throughout the offshore petrochemical sector for crew drinking water supplies on board platforms and FSPO’s for over 30 years.

atg UV Technology is the worlds’ leading provider of UV drinking water packages for the marine and offshore sector, and offer a range of standardised ‘off-the-shelf’ UV systems and skid package designs for potable drinking UV water treatment.

The standard UV packages can treat flow rates of 0.1 m3/hr to over 1,000 m3/hr. All solutions are designed to meet the high specification requirements of the marine and offshore industries.

In addition, we are one of the few suppliers in the world who can offer a solution for hazardous area installations for ATEX & IC CEX Zones 1 and 2 using a certified Ex d (flameproof) solution for the control & power panels.

A correctly sized medium pressure (MP) UV system will allow aquatic facilities to reduce residual chlorine levels down to as little as 0.5 ppm.  In addition, the polychromatic wavelengths of MP lamps eliminate problem chloramines, producing sparkling clear water, fresh clean air and significantly reduce skin irritations and sore ‘red’ eyes.

The NSF-50 requirements for aquatic health and safety regarding protection against the 17 known chlorine-resistant microorganisms such as Cryptosporidium outbreaks and Giardia are easily met by installing a UV system.

De-chlorination with UV light provides a chemical free alternative to feed water de-chlorination, both eliminating the need to deliver and store chemical on board, whilst providing a high-level of disinfection and therefore protecting RO membranes from bio-fouling.

UV disinfection is also proven to protect RO membranes and increase membrane life by eliminating harmful bacteria from feed water.

  • Inhibits biofilm growth on membranes
  • Protects against Microbial Induced Corrosion (MIC)
  • Reduces the maintenance and operating costs
  • Extends membrane life

UV disinfection is the treatment technology of choice for ballast water manufacturers worldwide. As a part of an approved Ballast Water Treatment package and one of the leading players globally, our UV disinfection systems will protect against the spread of invasive aquatic species and harmful microorganisms.

  • IMO approved disinfection solution for BWT
  • Chemical free solution, that does not increase the toxicity of the treated water or cause corrosion
  • Eliminates the transportation & storage of chemicals
  • Microorganisms cannot build resistance to UV light
  • No requirement for dilution before discharge
  • No effect on performance by variations in water salinity or types from different locations.

In modern fish farming, live fish are exposed to many microbiological threats whilst being transported in well-boats, from onshore and offshore aquaculture farming facilities.

Chemical-free UV disinfection is the treatment technology of choice, protecting against numerous harmful pathogens without affecting the waters natural chemistry, taste and odour.

Our new WF range is the perfect solution for well boat applications. The WF is the World’s most compact UV system, allowing for ease of installation into tight spaces, whilst also optimised to provide a high level of disinfection. Ultimately protecting fish, minimising vaccinations and increasing stock yields.
