Research: Thesis: “Removal of Ammonia from Aqueous Solutions using Ion- Exchange”. The work focused on trying to improve the ammonia removal process (ARP) developed by Foster Wheeler Environmental and ThermoEnergy by changing various operating conditions. The conditions tested were the use of various ion-exchange resins, using a lower concentration of ammonia in the waste effluent, heating the ammonia influent to 60 °C and 68 °C, adjusting the pH of the ammonia solution during ion-exchange and increasing the zinc concentration of the regeneration solution.
