atg UV Technology - Water sterilised to stringent standards

When it comes to sterilisation of drinking and process water, few industries bear the same tough demands as the offshore oil and gas sector - atg UV Technology is able to offer high-quality, high-throughput and highly effective equipment sales and rental services to meet these requirements.

The process of disinfecting water with UV light is a proven technology for drinking and process water in many industries. However, the high standards necessary for the oil and gas sector require equipment to be designed, engineered and certified far beyond the normal specification of many manufacturers.

From crew drinking-water supplies to large seawater-injection packages treating more than 10,000m3/hour, atg UV Technology can offer a range of packages to suit any water-treatment application, and has delivered hundreds of projects to the oil and gas sector worldwide for more than 30 years.

As the world's leading provider of offshore UV equipment, atg UV's engineering capabilities can fully meet the most demanding of offshore operator specifications, including:

  • ATEX/ECEX Designs/Zones 1 and 2/Ex-d, Ex-e, Ex-ia and Ex-p solutions
  • skid packages and containerised solutions
  • client-specified electrical, mechanical, design loads and documentation
  • multitechnology packages such as filters, pumps and dosing
  • pressure vessel designs - ASME VIII Div 1, PD5500 and EN13445
  • exotic materials such as duplex, super-duplex, copper nickel and titanium
  • specialist designs such as NORSOK, NiPH, GOST, DOSH, NSF and US EPA UVDGM.

UV is now the disinfection technology of choice for offshore operations, providing a simple, chemical-free solution that protects against all known bacteria, including chlorine-resistant microorganisms such as Cryptosporidium parvum and Giardia.

Atg UV Technology UV systems fully meet the guidelines for offshore potable drinking water set by the World Health Organization, providing a greater-than four-log reduction (99.99%) of harmful microorganisms in a single pass. Selected UV models are fully certified to meet the requirements of NSF-55 (Class 1 and Class 2) and NiPH (FHI Water Report 120) certified offshore potable water installations.

Atg UV Technology performed the original research and pilot trials into treating hydraulic operation fluids used to control subsea BOP systems with UV in order to prevent bacterial growth, and avoid the formation of solid particles, biofilms and microbial-induced corrosion (MIC).

For more than 30 years, atg UV Technology has successfully used UV to control microorganisms such as sulphate-reducing bacteria (SRB) in well injection applications. Collaborating with Conoco Phillips, atg UV Technology performed the original research for using UV treatment for SRB reduction for enhanced oil recovery in 1993. This led to the supply of a number of offshore UV treatment plants being installed in the Norwegian North Sea sector, with the Eldfisk and Ekofisk plants treating 4,500m³/hour and 4,000m³/hour per day.

Nominated for the 2015 Innovation Award, atg UV Technology has recently patented a unique chemical-free advanced oxidation process, known as Keratox, for treatment and removal of organic and chemical contaminants from produced water before environmental discharge or reinjection.

Using a unique TiO2 catalyst to create hydroxyl radicals, the Keratox advanced oxidation solution provides a final polishing technique to remove contaminants detailed on the OSPAR list of chemicals for priority action, such as polyaromatic hydrocarbons, BTEX compounds and phenols.

Atg UV Technology can offer equipment treating 1-6,000m³/hour in a single 20ft container, and has supplied some of the world's leading operators with equipment sale and rental solutions. This includes the world's largest pipeline project, the Nord Stream Pipeline in the Baltic Sea, which treated 3,000m³/hour of sea water and achieved a 99.9% reduction of SRB in a single pass through the UV system.
