  • UV disinfection for enhanced oil recovery and other oilfield applications

    One of the biggest challenges facing oil companies today is how to extract more oil from the discoveries made in the last 40 years. Estimates vary, but approximately 66% of the discovered oil gets left in the ground. The International Energy Agency has estimated that if, in the next 20 years, this figure could be reduced to 50%, then this would increase the world's recoverable oil by 1.2 trillion ...

  • Maintenance strategies for on-site water disinfection by ultraviolet lamps on dairy farms

    Bacteria have been detected in many water supplies on dairy farms, and the water used to wash milking equipment should be free of bacteria. This study evaluated two ultraviolet (UV) technologies, with and without automatic sleeve cleaning device, as on-farm water disinfection system. No fouling was observed during 6 months of continuous operation of the self-cleaning UV system. The dose provided ...

  • Sensor Setpoint Validation of Reclaimed Water UV Reactors

    ABSTRACTReclaimed water ultraviolet light (UV) disinfection system can be a critical component of a multiple barrier approach for public health protection. Current control methodologies rely upon assumed end of lamp life factors and sleeve fouling factors, which often result in overdosing when the lamps are new and the sleeves are clean and underdosing as the lamps ...

  • The Use Of UV For Dechlorination

    For many years chemical disinfection techniques have been used to provide microbiologically pure water for industrial and domestic use. Free chlorine, typically introduced by municipal water treatment plants in gaseous form, has been employed for many decades as a primary oxidising agent for the control of microbiological growth. Free chlorine can also be introduced through the injection of ...

  • Evaluation of UV System Performance and Challenges of UV Validation Testing at the Laguna County Sanitation District

    ABSTRACTThe Laguna County Sanitation District (LCSD) Water Reclamation Plant, with a design capacity of 3.7 mgd, produces tertiary water that was designed to meet California Title 22 unrestricted re-use criteria. The disinfection in LCSD is provided by an in-line Aquionics Model 7500 medium pressure UV system containing four UV banks. California Department of Health and Services (CDHS) require ...

  • A Regulatory Perspective on Maintenance of Disinfection Systems

    ABSTRACTThe Clean Water Act contains requirements to set water quality standards for all contaminants, including bacterial contaminants, in surface waters. Wastewater treatment cannot be expected to remove all of the bacterial contaminants, and as a result, many organisms remain in the waste stream. Therefore, disinfection of treated wastewaters is designed to reduce bacterial numbers to a safe ...

  • The Light at the End of the Tunnel - How to Successfully Operate a UV Disinfection System

    ABSTRACTOver the past ten years, ultraviolet (UV) technology has become a commonly applied method of disinfecting of wastewater effluent. UV disinfection involves passing wastewater effluent through a confined chamber with rows of underwater lamps emitting UV energy. Viruses and bacteria become inactivated upon exposure to dosages of UV energy, thereby disinfecting the wastewater. The UV system ...
