  • 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 ...

  • The Alamitos Barrier Recycled Water Project

    Groundwater pumping in the Los Alamitos, California area over the last century has caused groundwater levels to drop, allowing seawater to intrude into the local groundwater aquifer. To prevent additional infiltration by seawater, a coastline barrier of wells injecting fresh water has been in place since 1965. Until recently, imported potable drinking water was injected into the aquifer. However, ...

  • UVC: Florida hospital puts HVAC maintenance under a new light

    HVAC system downtime during coil cleaning can compromise humidity and temperature control, potentially leading to air quality or comfort problems. Florida Hospital has found that high-output ultraviolet-C lights installed in the AHUs reduce or eliminate coil- cleaning programs — yielding ongoing energy savings, a reduction in HVAC system maintenance, and the elimination of cleaning ...

The existing lagoon system with seepage cell was not removing phosphorous cost effectively and odors ...

  • 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 ...
