Advanced Wastewater Treatment for Alaskan HB80 wastewater discharge regulations
atg UV Technology have developed a range of high quality, marine specification UV disinfection systems and skid packages for the final treatment of wastewater discharges from cruise ships. The UV disinfection systems are sized to comply with the Alaskan HB80 wastewater discharge regulations that require cruise ships and other large passenger vessels planning to discharge effluent wastewater into state waters to first provide disinfection and treatment of the wastewater using series of advanced water treatment technology's.
A key requirement of the Alaskan HB80 environmental regulations is the inclusion of UV disinfection systems as a final barrier against harmful microorganisms such as E-Coli and Cholera that form part of the approved on board advanced water treatment plant. The HB80 regulations require UV systems to provide a 3 log reduction (99.9%) of Faecal Coliforms and E-Coli with a single pass through the UV chamber.
The systems are sized to provide the minimum 3 log (99.9) disinfection at water quality’s as low as 30% UV Transmittance (UVT). In addition to the required high disinfection performance, the marine environment and location of the UV systems in the bows of the ship require specially designed and engineered UV reactors and upgraded local control panels to overcome high ambient temperatures, humidity of up to 100% and high vibration environments.
Featuring a range of high specification design features and functions specifically designed for the marine industry, atg UV Technology’s marine solution UV Systems (SX Range, UVLA Range and UVM Range) have become the market leading design for cruise ships and marine vessels worldwide. The marine specification often requires engineering beyond the scope of many UV manufacturers.
