Our water environment is greatly impacted by the presence of microbial contaminants which is of great concern it terms of public health exposure. Full-scale conventional and state-of-the-art wastewater utilities have been found to release pathogens and resistant bacteria in the environment. Management and minimization of microbial pathogens and antibiotic resistant bacteria in wastewater treatm...

The requirement to minimise the impact of domestic effluent on public and environmental health is an important component of best management practice for onsite wastewater management. The numerous guidelines prepared by state and local regulators recognise the importance of adequate distribution and assimilation of nitrogen from domestic wastewater. As this element is an essential microbial and ...

In this paper, lumped-parameter models (LPMs) were developed and utilized to simulate nitrate concentration in the groundwater of Gaza City and Jabalia Camp (GCJC) in the Gaza Coastal Aquifer (GCA) in Palestine. In the GCJC area, nitrate levels exceed the maximum contaminant level (MCL) of 10 mg/L NO3-N (45 mg/L NO3) in many wells. Elevated nitrate concentrations in the groundwater of GCJC area...

This study describes the temporal and spatial variability of bacterial communities within a combined sewer system in England. Sampling was conducted over 9 months in a sewer system with intensive monitoring of hydraulic conditions. The bacterial communities were characterized by 16S rRNA gene-targeted terminal restriction fragment length polymorphism analysis. These data were related to the hyd...

Mission To safely collect and treat wastewater in compliance with all regulatory requirements using state‐of‐the‐ art technology in the most cost‐effective manner in order to improve the environment and enhance the quality of life in Fairfax County. Focus The Wastewater Management Program includes wastewater collection and conveyance, wastewater treatment, and planning and monitoring program a...

In this paper, a data-mining approach for modeling pumps in the wastewater preliminary treatment process is discussed. Datamining algorithms are utilized to develop pump performance models based on industrial data collected at a municipal wastewater processing plant. The performance of wastewater pumps is described by two parameters, pump energy consumption and water flow rate after the pumps. ...

Current urban water management practices aim to remove stormwater and wastewater efficiently from urban areas. An alternative approach is to consider stormwater and wastewater as a potential resource substitute for a portion of the water imported via the reticulated supply system. A holistic view of urban water resources provides the framework for the evaluation of the demand for water supply, ...

Introduction Hanoi is currently undergoing a process of intensive industrialization and modernization. The population in the smaller Hanoi urban zone has risen dramatically from 300,000 in 1954 to its current population of more than 1.7 million which is 60% of the total population in the area of greater Hanoi. It is predicted that this will rise to 2.5 million amongst 4.5 million of total popul...
