Wastewater treatment is essential to protecting the environment and human welfare. Water is a resource that is fundamental to human life, which makes taking action to protect the resource on the forefront of research. Treated wastewater effluent is a possible source that can pollute receiving water bodies and cause contamination. It is often discharged into larger bodies of water that are used ...

Background: The quality of drinking water is directly related to community health. Therefore, improving the reflects positively on health situation in general. studies that deal with city Baghdad terms chemical or microbial content are very scanty.
 Objective: current review highlights most important and research articles concern water, both bottled tap biological contamination chemophysic...

S torage and distribution systems for water and water-based fluids are both critical and ubiquitous in every industry, geography, and culture. Large scale industrial water handling systems require water storage and distribution for a range of applications from simple thermal control (cooling and heating systems) to Purified Water (PW) production and delivery. For more than 40 years, manufacture...

The aim of this study was to determine the feasibility of combining water quality analysis with different biomarkers to characterise the relationship between anthropogenic contamination and biotic response in the Sinos River, southern Brazil. Wistar rats were studied using three biomarkers combined with physical, chemical and microbiological analysis to assess the effects of pollution at four s...

135 ABSTRACT: Heavy metals and dyes are major contributors in contamination of water streams. These contaminants enter into our ecosystem, thus posing a significant threat to public health, ecological equilibrium and environment. Thus a combined discharge of these contaminants results in water pollution with high chemical oxygen demand, biological oxygen demand, color, particulate matter, suspe...

nowadays, application of unconventional water such as wastewater is one of the strategies for preventing water deficit. this study was conducted to evaluate effect(s) of treated wastewater application on microbial and chemical contamination of soil and wheat (chamran v.). five treatments included t1 (irrigation with 100% fresh water), t2 (75% fresh water + 25% wastewater), t3 (50% fresh water +...

background and purpose: water is the most important limiting factor of sustainable development. poor quality of water sources and lack of appropriate management in some regions are the main reasons of water crises in the country. this study was conducted to assess water sources quality and the trend of their change in rural area of sabzevar county in a five year period. materials and methods: i...

In Bangladesh, arsenic contamination of groundwater, microbial contamination of surface water and seasonally variable rainfall make reliable access to acceptable quality drinking water a challenge. Arsenic-iron removal plants (AIRPs) are a relatively inexpensive way of removing arsenic from groundwater for access to safer drinking water. This study evaluated the performance of 21 (of 105) AIRPs...

Many South Africans do not have access to safe drinking water, so they have no alternative but to use water from contaminated sources that poses a health hazard. This poor state of affairs appears to be deteriorating. In order to distinguish safe from unsafe sources, the aim of this study was to adapt the well-known MTT (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide) assay into a...
