    Ultraviolet disinfection systems for the offshore potable drinking water

    atg UV Technology are the market leader for UV systems designed to treat potable drinking water for offshore crew water supplies. UV is now the disinfection technology of choice, providing a simple chemical free solution to protect against all known bacteria and harmful microorganisms, including chlorine resistant microorganisms such as Cryptosporidium and Giardia. Available as skid mounted, duty / standby solutions, atg UV Technology’s offshore UV drinking water packages are included as part of the on board water maker, typically installed following desalination by an RO package or Flash Evaporator.

  • Drinking water solutions for the UV disinfection performance

    Problem: Waterborne pathogens can cause serious disease outbreaks. Drinking water disinfection forms the final barrier between these pathogens and humans. For drinking water disinfection, ultraviolet (UV) light has proven to be the best method for inactivation of Cryptosporidium parvum and Giardia lamblia parasites found in natural waters. Organic matter and suspended particles in water absorb and scatter UV light, interfering with pathogen inactivation by UV irradiation.

    Ultraviolet disinfection systems for the swimming pools industry

    Ultraviolet disinfection is now an established method of water treatment for Swimming Pools, Spas, Hydro Pools, Splash Pads and Water Features, and has become the preferred treatment choice for a number of leading international leisure brands. atg UV`s range of treatment systems are proven to improve the swimming pool environment by improving water quality, air quality and safety, leading to increased customer satisfaction. UV systems not only provide disinfection against the 17 known chlorine resistant micro-organisms, such as Cryptosporidium and Giardia, which have a thick outer membrane making them highly resistant to traditional Chlorine disinfection, UV also destroys chloramines. Chloramines are formed when free chlorine reacts with organics, such as sweat, body fats and urine, brought into the pool environment by bathers.

    Ultraviolet disinfection systems for the drinking water inspectorate

    With atg UV systems treating in excess of 2500 m3/hr daily, Ultraviolet disinfection is no longer an ‘emerging` technology.  A number of Water Treatment Works across the world are now investing heavily in Ultraviolet technology as the threat of chlorine resistant parasites, such as Cryptosporidium and Giardia, continue to pose a serious risk to water companies and their customers. To this end, in the UK, the DWI have issued their guidelines for UV operation and system selection to the UK water industry.  A key feature of their guidance is UV system validation.  Validation refers to a series of 3rd party testing to ensure the performance of an Ultraviolet system design under a range of operating environments.

  • Ozone/UV systems for swimming pool water treatment

    Studies have proven that chlorine use has negative consequences due to the formation of byproducts, i.e. chlorinated organic compounds and chloramines. Irritation of eyes and mucous membranes, drying out the skin as well as “chlorine smell” are well known troubles. However, these byproducts also accelerate the corrosion in pool halls and significant risk is given by their toxicity (chloramines, combined chlorine) and/or carcinogenicity. Higher rate of asthma prevalence is one of the consequences. These are the reasons why the combined chlorine content - as a marker of chlorination byproducts presence - is to be monitored and why its limit values are specified by authorities. To meet the limits can be tedious and expensive because more water has to be changed and heated up. Chlorine disinfection is not sufficient to prevent infections caused by some waterborne pathogens as dangerous protozoan parasites Cryptosporidium parvum and Giardia lamblia.

  • Advanced Ultrafiltration Modules

    The Q-SEP Ultrafiltration membranes incorporate high-strength, hollow fibers that deliver superior performance without the risk of fiber breaks. They are made from a hydrophilic polyether sulfone material with excellent low fouling characteristics. These hollow fiber membranes operate under a pressurized inside-out flow configuration for superior performance. These hollow fiber UF membranes offer reliable removal of turbidity, microorganisms & viruses. Turbidity can be reduced to less than 0.05 NTU. Typically, a 6-log removal for bacteria, giardia & cryptosporidium, while a 4-log removal for viruses, can be achieved. The Q-SEP modules contain an advanced UF fiber, prepared by an innovative patented cloud point precipitation method. This method ensures a very uniform pore size distribution and high pore density in the membrane. As a result, the product water quality from the modules is significantly better than the quality from conventional UF modules at a very operating pres
