Drinking water

• We compare drinking water treatment systems, a NF unit and a conventional treatment. • Sustainable water quality improvement using renewable energy is demonstrated. • Membranes are more efficient than conventional treatment removing micropollutants. • Membranes reject hydrophobic compounds causing

The water quality from open hand-dug wells in Mtopwa village in Blantyre was assessed over a period of four months. The research entailed conduction of experiments using recommended methods to analyse selected water quality parameters. Interviews were also conducted with the Blantyre City Assembly (

Drinking water treated with chlorine or chlorine dioxide contains a mixture of different chlorine species. Their identification, especially at low concentrations, is still problematic because of the number of compounds produced, especially when mixtures of chlorine and chlorine dioxide are used. Thi

Arsenic in drinking water is a factor that has recently been shown to be a possible cause for an elevated bladder cancer risk in northern New England. More than 40% of the population in this region uses private wells as the primary drinking water source. Point-of-entry (POE) and point-of-use (POU) a

Brine disposal remains a key consideration when employing ion exchange (IEX) for nitrate removal. To circumvent this issue, research was conducted into developing an immersed membrane bioreactor (MBR) as a replacement for ion exchange. This paper compares the economics of the two process options whi

This paper presents the results of a research on direct drinking water treatment through an ultrafiltration pilot plant unit using spiral-wound membranes (3500 MWCO). The source of water is the Guarapiranga Reservoir, an eutrophicated water body located in the metropolitan region of São Paulo, Brazi

The present work is a comprehensive evaluation of drinking water quality from various regions of Greece. The physicochemical parameters investigated were conductivity, total dissolved solids and pH, as well as related to the treatment of drinking water such as chloride, potassium, calcium, magnesium

Water scarcity in Mediterranean regions has led to projects that increase water resources by desalination. In this context, it is planned to expand and improve the drinking water treatment plant of the Llobregat River near Barcelona (Catalonia, NE Spain), building the largest electrodialysis reversa

The aim of the present study is to bring in our modest contribution in evaluating the water state in the sources that feed Constantine city. For the purpose of quality determination, analyses based on the measure of some physico-chemical and bacteriological parameters have been realized on samples t

A hybrid process, consisting of ozonation and membrane filtration, followed by activated carbon filtration, was studied in demonstration scale for the drinking and service water production from surface water in Thailand. The main focus of this study centred on the evaluation of the entire process, e
