This study focuses on the water quality assessment (feed, product and
brine) of the pilot adsorption desalination (AD) plant. Seawater from
the Red Sea is used as feed to the AD plant. Water quality tests are
evaluated by complying the Environmental Protection Agency (EPA)
standards with major primary and secondary inorganic drinking water
pollutants and other commonly tested water quality parameters. Chemical
testing of desalinated water at the post desalination stage confirms the
high quality of produced fresh water. Test results have shown that the
adsorption desalination process is very effective in eliminating all
forms of salts, as evidenced by the significant reduction of the TDS
levels from approximately 40,000 ppm in feed seawater to less than
10 ppm. Test results exhibit extremely low levels of parameters which
are generally abundant in feed seawater. The compositions of seawater
and process related parameters such as chloride, sodium, bromide,
sulfate, calcium, magnesium, and silicate in desalinated water exhibit
values of less than 0.1 ppm. Reported conductivity measurements of
desalinated water are comparable to distilled water conductivity levels
and ranged between 2 and 6 μS/cm while TOC and TIC levels are also
extremely low and its value is less than 0.5 ppm.
