Water from the concentration ponds, 1200 Feddans in surface area, is pumped into the sodium Sulphate plant. The annual rate is around 140 million cubic meters containing 340.000 tons of total dissolved salts.
At present , 100.000 tons of sodium Sulphate, 200.000 tons of sodium chloride are extracted and 27.000 tons of magnesium sulphate are expected to be produced in the near future.

After the recovery of anhydrous Sodium Sulphate, the mother liquor left is concentrated further through secondary concentration ponds. The sodium chloride is precipitated by solar evaporation of the mother liquor, resulting in a large stockpile of coarse raw NaCl.

The main target is to produce 200 000 tons/year of Sodium Chloride, Half of this Quantity is is industrial salt for Chloral kali Processing while the other half is fortified by iodine (30ppm to 70ppm) and specified for table salt and food processing industries.

The plant includes classification, dewatering, edible salt preparation, drying and packing of the final products. The following is a review of the process in brief.
