The impact of untreated and partially treated domestic wastewater on rivers and community water sources continues to raise health and safety concerns. The organisms of concern in domestic wastewater include enteric bacteria, viruses, and protozoan cysts. Table 1 summarizes the most common microorganisms found in domestic wastewater and the types of human diseases associated with them. Based on ...

in order to investigate the effect of domestic wastewater and normal water (well water) on soil chemical properties and alfalfa yield, a research project was conducted for three years in chahartakhteh research station. the experiment was performed in randomized complete blocks design including four treatments in three replications. treatments were as follows: t1: irrigation with normal water at...

To develop a better understanding of the issues and best practices related to the use of treated effluent to help maintain river flows and habitat, the Conservancy commissioned a study to summarize the state of the science. The use of treated wastewater effluent is becoming a more prominent factor in Arizona’s overall water management strategy. Treated effluent contains a wide array of chemical...

background: today, treated wastewater recycling and reuse has been considered for agricultural irrigation. this can potentially cause health and environmental hazards. since accessing the engelberg index for sewage is a necessity, this study was undertaken on integrated stabilization ponds (isp) of isfahan east wastewater treatment plant, isfahan, iran. methods: this cross-section study was con...

Wastewater generated by domestic, municipal, and industrial sectors has been increasingly used, particularly in dry areas, to provide water and nutrients to agriculture, aquaculture, and agroforestry systems. While such use helps in income generation and livelihood resilience amid water scarcity, use of wastewater in untreated or inadequately treated forms may result in negative impacts on huma...

Reuse of treated effluent is a highly valued water source in Palestine, however with limited success due to public health concerns. This paper assesses the potential pathogens in raw, treated and reclaimed wastewater at Albireh urban wastewater treatment facility, and provides scientific knowledge to update the Palestinian reuse guidelines. Laboratory analyses of collected samples over a period...

Given the current demographic trends and future growth projections, as much as 60% of the global population may suffer water scarcity by the year 2025 [9]. In addition to water scarcity, water quality deterioration is expected to intensify in resourcepoor countries in dry areas, due to human activity and climate change. It is projected that water scarce countries will have to increasingly rely ...

The occurrence, concentrations, patterns, and loads of 17 2,3,7,8-substituted congeners of polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) were determined in treated wastewater collected at the outlets from 14 wastewater treatment plants (WTPs), divided into three size categories. The analysis also considered the effect of wastewater outflow on the final conc...

This data article describes a facile method for production of an adsorbent from Tamarix hispida wasted wood and modified by lanthanum metal for fluoride ions removal from wastewater. The main characteristics of the adsorbent consist of BET surface area, functional groups, and elemental analysis is presented. The data for attenuating the pollutants from a real wastewater treatment which was prov...
