Ammonium is the critical contaminant to be removed from a fertilizer factory wastewater. Currently, industrial effluent treatment consists of two stabilization ponds. Enhancing the efficiency of the industrial effluent treatment, a fraction of the effluent could be reused, decreasing the final volume discharged. Large land area is available in the factory facility.Constructed wetlands can be a good solution to nitrogen removal (Kadlec and Wallace,2009). In Argentina this technology is poorly implemented. The aim of this study was to evaluate the feasibility of using hybrid wetland systems for the treatment of an alkaline effluent with high concentrations of ammonium from this fertilizer factory.
