Kinetic Study of Nitrite Removal from Municipal Wastewater Using Ion Exchange Resins

Abstract:

Nitrite removal from municipal wastewater is mandatory considering the treated wastewater reuse. Removal on an anion exchanger leads to simple wastewater treatment installations, easy to handle, to exploit and to maintain. This study reports on the performance of anion exchange resin on removing nitrite from synthetic solutions. Equilibrium data could be well fitted using the Langmuir model, confirming ion exchange without any parallel mechanisms. Kinetic study of the process is evaluated using the shrinking core model and the dominant rate mechanism is estimate.
