There are several methods to remove organophosphorous compounds from water. Chemical oxidation is one such method but it is expensive and

wastes [ 1 – 3 ]. High nitrate concentrations in drinking water are related to many health threats such as blue baby syndrome and cancer [ 4 , 5 ]. Furthermore, the release of nitrate to water bodies can promote algal blooms [ 6 ]. For these reasons
% using Ag–MgO/Syltherm 800 under high concentrations. As it can be seen in the previous section, researches on the effect of using hybrid nanofluid in the PTC did not take a high interest in comparison with mono nanofluid. This study aims to examine the
different base fluids (i.e. water, Ethylene Glycol (EG) and oil). Finally, these examined tests were affected by the different volume or weight concentrations and variable mass or volume flow-rate [ 10 ]-[ 12 ]. The numerical side took more attention
