Abstract :
Background and Objective: Recharge of wastewater contains nitrogen compounds into surface water led to excessive alga growth and eutrophication in lakes and rivers. This study aimed to investigate nitrogen compound removal from aqueous solution by modified clinoptilolite and air stripping and optimize the process using experimental design and central composite design (CCD).
Material and Methodology: In this study, adsorbent (clinoptilolite) were modified ferric chloride. The experiment was designed using the CCD method and the effect of pH, adsorbent doses, contact time, ammonium initial concentration was surveyed by modified clinoptilolite. In addition, contact time, pH, and aeration rate were studied through air stripping.
Findings: According to obtained results, the maximum ammonium adsorption through modified clinoptilolite as obtained at pH, contact time, initial concentration, and adsorbent dose which removal efficiency was 84.16%. In addition, the optimum condition using air stripping was obtained at an aeration rate of 4 mL/min, time of 3.99 h, and initial concentration of 10.3 that removal efficiency was 96.4%.
Discussion and conclusion: according to the results obtained and the high efficiency of the processed studied in this work, modified clinoptilolite can be used as low cost and effective absorbent for nitrogen compound removal.
