چکیده
|
The goal of this study was to identify the treatment efficiency of various membrane modules in the treatment of yanbu groundwater. the membrane treatment efficiency was calculated from the removal percentages of groundwater conductivities,associated with tds,of the groundwater at yanbu city. the experiment work involved four commercial membranes and they were polyvinylidene difluoride (fp100),polyethersulphone (es404),polyamide low-pressure film (afc40) and polyamide high-pressure film (afc99). different pressure values were applied on each membrane type to see the effect of the pressure on the treatment efficiency and thereby selecting the optimal operating pressure for the treatment of the groundwater. the ideal membrane for the treatment was selected based on a comparison between the four membranes. the optimal operating pressures for the first three membranes fp100,es404 and afc40 were 10,30 and 60,respectively. however,the optimal operating pressure for afc99 membrane was 61.8 bar which was not similar to the maximum operating pressure reported in the manuals that was 64 bar. results showed that applying higher pressures would increase the treatment efficiency except for the last membrane type afc99. it was found that the best membrane module for the treatment of the groundwater at yanbu city would be afc40 with a potential to reduce fouling (prefiltration) in advanced water treatment plants with 7% treatment efficiency. © 2017,university of mohammed premier oujda morocco.
