Abstract: The indigo trisulfonate method has been proposed in the current edition of

Abstract: Three methods of estimating effective germicidal ultraviolet (UV) dose in a collimated beam medium pressure UV system were analyzed: (1) A bioassay; (2) a mathematical model; and (3) a chemical actinometer. The bioassay ...

Abstract: The results of an investigation of the effect of antimicrobial coatings on inactivating microbes on and within the media used in cloth media disk filtration systems are presented herein. Four filter fabrics were evaluated ...

Abstract: Human dose-response data from seven pathogens commonly associated with waterborne illness were used in conjunction with acceptable levels of risk specified by the United States EPA to determine an allowable particle limit ...

Abstract: In the design of an ultraviolet (UV) disinfection system for a wastewater treatment plant (WWTP), the number of lamps necessary to meet the permit requirements must be determined. Factors influencing the required number ...

Abstract: A model is presented to quantify microbial occlusion in effluent particles and improve understanding of the removal and inactivation of occluded microorganisms in filtration and disinfection systems. Microbial occlusion ...

Abstract: The water-quality parameters influencing the performance of a UV disinfection system in the tailing region (typically apparent at doses greater than 30 mW⋅s/cm

Abstract: Due to California’s stringent hazardous waste (HW) classification regulations, high-capacity adsorptive media (AM) used for the removal of arsenic from potable water are likely to be classified as HW if operated to ...

Abstract: Bacteria can synthesize cytoplasmic granules known as polyhydroxyalkanoates (PHAs), which are carbon and energy storage reserves, from organic carbon when subject to stressful environmental conditions. PHAs are also ...
