Wastewater reuse has become an important part of the urban water supply portfolio in water stressed regions. Effective wastewater treatment processes are critical to protect public health during water reuse practices. However, the microbial removal efficiencies in wastewater reclamation plants are not routinely monitored due to the lack of a simple quantification method. This study applied a ne...

An ozonation pilot plant was installed at the Montréal Urban Community Wastewater Treatment Plant (MUCWTP) to assess the feasibility of employing a full scale ozone disinfection system. Wastewater characteristics such as turbidity, COD, TOC, BOD, pH, ORP and suspended solids were monitored to assess their effect on ozone disinfection. Fecal conforms (FC) were used as indicators to measure disin...

Vietnamese farmers' health-risk awareness, knowledge, and practices related to their use of wastewater and human excreta was investigated in an anthropological study by a multidisciplinary team in peri-urban Hanoi and Nghe An Province. Farmers identified health risks associated with their use of excreta and wastewater, but they viewed these as unavoidable risks related to production. They perce...

Wastewater reuse presents a promising solution to the growing pressure on water resources. However, wastewater reuse implementation faces obstacles that include insufficient public acceptance, technical, economic and hygienic risks and further uncertainties caused by a lack of awareness, accepted standards, uniform guidelines and legislation. So far, there are no supranational regulations on wa...

The disparity between volume of wastewater generated and treated has resulted in severe water pollution and eutrophication of the water bodies in most Indian cities. Constructed wetlands (CWs) present a low-cost wastewater treatment option; however, field scale studies with real life wastewater are limited. Eichhornia crassipes (water hyacinth), Typha latifolia (Typha) and Pistia stratiotes (wa...

OBJECTIVE To use Monte Carlo simulation to assess the uncertainty and variability of tobacco consumption through wastewater analysis in a city. METHODS A total of 11 wastewater treatment plants (WWTPs) (serving 2.2 million people; approximately 83% of urban population in Dalian) were selected and sampled. By detection and quantification of principal metabolites of nicotine, cotinine (COT) and...

Most of Urban Wastewater Systems (UWS) have been managed separately, without considering any interaction between sewer systems, Wastewater Treatment Plants (WWTPs) and the receiving waters. Nowadays, the conventional practice has changed, introducing the integrated management concept into the river basin scale. The goal of the project is to develop a modular Environmental Decision Support Syste...

This can create si...

There is an increasing trend to require more efficient use of water resources, both in urban & rural areas .The aim of the present research work was to determine the behavior of various parameters of the pharmaceutical wastewater. The company produces bulk drugs, antibiotics, pain killers, food additives, personal care products and others. It is important for the industry to develop its own was...

Urban agriculture (UA) is practiced inside (intraurban) or on the outskirts (periurban) of a town or a city. While it focuses on raising food and animal crops, it includes recycling household waste and wastewater for agricultural purposes, the processing and distribution of different food and non-food products using human and material resources, products, and services that are found in the same...
