This simulation study investigates the treatment performance of a French style single stage vertical flow constructed wetland using a zeolite layer in order to increase ammonia removal. For the modelling exercise, the CW"2D biokinetic model of the HYDRUS Wetland Module is used. The calibrated model is able to determine the effect of different depths of the zeolite layer on ammonia removal in order to optimize the design of the system. For calibration of the model, hydraulic effluent flow rates as well as influent and effluent concentrations of COD and NH4-N have been measured. To model the adsorption capacity of zeolite, Freundlich isotherms are used. The results present the simulated treatment performance within three different depths of the zeolite layer, 10 cm (default), 15 cm and 20 cm respectively. The increase of the zeolite layer depth leads to a decrease of the simulated NH4-N effluent concentration.
