Abstract: During droughts, potable water agencies may need to increase supply or reduce demand. Water agencies have many options for water demand management (WDM), including low flow toilets, showerheads, faucet aerators, educational ...

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: Agricultural water use is the leading cause of groundwater overdraft in California. However, agencies tasked with managing groundwater resources do not have access to accurate and reliable measurements of groundwater ...

Abstract: In 2017, urban water retailers in California reported 364  million m3 in real water losses within their distribution systems, representing on average 7.12% of their total water delivered that year. Recognizing the value ...

Abstract: Soluble manganese (II) and amorphous and crystalline manganese (IV) oxides were investigated as catalysts for the Fenton-like decomposition of hydrogen peroxide into oxidants and reductants. 1-Hexanol was used as a hydroxyl ...

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: 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 ...
