English Abstract
Natural Jordanian Zeolite was collected from different sites of south Jordanian tuff, characterized by FTIR, XRD, zeta potential and were further used as an ion exchange resin.
Also, a glass resin containing the ligand tris-(2-aminoethyl)amine that is covalently attached to silica glass was prepared via the sol-gel method in order to be used as another ion exchange resin.
Both resins were used as softening materials to purify water.
A study was carried out on a sample of natural zeolite in order to optimize the pH and flow rate for the ion exchange process between hard ions in water (Ca2+ and Mg2+) and the resin ions.
It was found that pH 5 and a 4-5 ml/min flow rate gave the best results for the exchange process with removal efficiency of 69.50% for calcium ions and 62.10% for magnesium ions.
A pre-treatment unit before desalination process was constructed utilizing a column packed with the ion exchange material.
The purpose of this unit was to reduce the seawater desalination cost based on decreasing the amount of scale that is usually formed during the desalination processes.
The idea of this unit was based on an auto-regeneration (AR) of the ion exchange material using the same feed seawater.
AR process was examined using each of the resins; natural zeolite or synthetic glass resin prepared by the sol-gel method.
Samples were collected during the elution of seawater through the column and were then subjected to analysis of hardness (Mg2+ & Ca2+) and sodium ion concentration.
Satisfactory results were obtained for the two tested resins.
In order to enhance the efficiency of the pre-treatment constructed unit, effect of the ultrasound waves on the ion exchange process was investigated.
The eluate Mg- Ca rich segments were further treated with a nanofilter to get rid of the remaining hardness.
