STUDY OF SOME PHYSICAL AND CHEMICAL PROPERTIES OF WATER THAT GOES IN, THEN OUT OF THE DESALINATION PLANT AT AL-KHUMS CITY

The analysis of entering water samples, gave an average value for pH (7.98), but yielded water samples show a slight change in the pH (8.06), while the value of conductivity EC for sea water was (53501µs/cm), then, significant decrease has been recorded in yielded water samples to become (32.032µs/cm). The chemical analysis also showed a major difference in the measurement for both of total dissolved salts TDS, and salts causing hardness TH, between entering and yielded water samples, as same as for sodium and potassium, where the average value of their concentrations in water samples that goes inthe desalination plant were (10380ppm)&(444ppm), to become (5.358ppm)&(0.24ppm)in water that goes outof desalination plant, respectively. A big difference was also observed in the average concentration of chloride and sulfate anions, in which the amount of chlorine was (19644ppm)and for sulfate (2752ppm)insea water, however at yielded water bothof them were (2.292ppm)and (1.389ppm)respectively.
