  • Illuminating Ultraviolet Disinfection for High-Level Reuse in Florida

    Chlorine has been the mainstay of the wastewater disinfection industry for more than 100 years due to its effectiveness, low cost and availability. However, due to various problems associated with chlorine, the Hillsborough County, Florida Water Resource Services Department decided to replace the high-level reuse water chlorine gas disinfection system at the Valrico Advanced Wastewater Treatment ...

  • Disinfection performance testing of high-efficiency ultraviolet water treatment chamber

    When introducing a disinfection product which incorporates new technology, it is essential that the methods and testing used to quantify the performance of those systems follow protocols which are technically sound and which are accepted by the scientific and technical community within the industry. These protocols must be applied precisely and rigorously in order to ensure accurate, repeatable ...

  • The Benefits Of UV Disinfection In The Pharmaceutical Industry

    The quality standards required for purified water in the production of pharmaceuticals have never been stricter, with manufacturers having to conform to an ever increasing number of international standards. Craig Howarth, Managing Director of Hanovia Limited, introduces a number of interesting new developments in UV technology for disinfection and dechlorination. ...

  • Ultraviolet Light Oxidation of Free-Chlorine in Water

    Chlorine is the most frequently used chemical for water disinfection. Many industrial and commercial manufacturing facilities cannot tolerate the introduction of chlorine into the process because of contamination and unwanted chemical reactions. Chlorine affects the flavour and odour of drinks and fluids, accelerates corrosion on process vessels and piping, and can also damage delicate process ...

  • Velocity Profiling Versus Checkpoint Bioassay for Performance Testing of UV Disinfection Systems

    As the recycled water industry is shifting from the use of theory based design of UV disinfection systems to a performance based design approach, there must be method for correlating the performance of one pilot-scale UV disinfection system to that of a full-scale system. Two methods for using existing performance data for the design and operation of future UV systems are presented in this ...

  • Case study - Floating covers reduce TSS, improve chlorine disinfection

    Problem: Algae and ultraviolet (UV) rays were adversely affecting chlorination in an upstate New York reservoir and Southern Florida WWTF. Algae was shielding embedded bacteria from chlorine, making the bacteriacide ineffective, thus requiring the chlorine dosage to be increased. Algae increased the chlorine demand along with exposure to UV which dissipates un-stabilized chlorine. Both ...

  • 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 ...

  • Use of CFD Modelling to Optimise the Design of Upper-room UVGI Disinfection Systems for Ventilated Rooms

    AbstractThe installation of upper-room ultraviolet germicidal irradiation (UVGI) devices in ventilated rooms has the potential to reduce transmission of infections by an airborne route. However, the performance of such devices is dependant on several factors including the location of the lamp and the ventilation airflow in the room. This study uses a CFD model to evaluate the performance of UVGI ...
