Abstract: High nitrogen wastewater can be treated efficiently by a combined or hybrid constructed wetland system. The objective of this study was to find appropriate conditions for plant harvesting method. Four units of lab-scale combined constructed wetland module made of plastic sheet with 0.4x0.8x1.16 m were used. The removal efficiency was around 60-69% for nitrogen (TN). The reactor with half harvesting showed the highest nitrogen uptake in plant with 2.8 gN/g.dry wt. The plant growth in the module with cutting plants showed the highest growth rate, 0.8 cm/d in height and 1.4 plant/m2.d in density.
