Djendjen River is one of the largest rivers in the region of Jijel (Algeria). Human activities such as urban discharges, industrial, agricultural, and livestock have significant effects on the quality of water. The present study attempts to evaluate the quality of water along the banks of the Djendjen River at different sampling sites, using physico-chemical and bacteriological methods. The col...

fluoride is one of the most important elements in the composition of teeth and bones. this element can enter the body via different ways. however, drinking water is the most important way to receive fluoride by a lot of people. an increase in fluoride level in the body causes dental fluorosis and its absence leads to teeth decay. standard rate of fluoride in drinking water is determined by the ...

The Clean Water Act established a water quality standards approach for regulating water quality, with the US Environmental Pro...

Background: This retrospective study aimed to investigate the physicochemical properties of drinking water sources in Ethiopia and compare the water quality with the health-based target. For this purpose, the water quality database of Ethiopian Public Health Institute (EPHI) from 2010 to 2016 was used. Methods: The concentration and other properties of the water samples were analyzed according...

background: reverse osmosis (ro) is an increasingly common method of desalination. a full scale water desalination system by membrane technology (ro) evaluated in a southern city (jask) in iran. methods: first, data collection on water supply and network were performed. analysis on most of the water quality parameters (turbidity, ph, ec, cl-, na+, alkalinity, ca, na, k, no3, no2, fe, mg, mn, nh...
