Abstract
The aim of this project was to remove chloride ions from Eshidiya industrial waste water to be reused in the flotation cells. The industrial wastewater was treated by passing it through ion exchange column. During the experiments, two types of resins were used: anion resin and mixed resin (cation / anion).The selectivity coefficient and the separation factor were calculated in those experiments and were found to be within the theoretical limits. The highest chloride ions removal efficiency which was reached in this process was 96.4% when the height of resin in the column was equal to 40 cm and the flow rate was equal to 0.12 liter/min. It was evident that this treated wastewater can be recycled to the flotation cells in the Jordan Phosphate Company, and the blow down water can be used for agricultural purposes.
