Mathematical Modelling and Parameter Estimation for the Design of Constructed Wetlands

Efficiency of waste water treatment in a subsurface constructed wetland depends on influent water quality, quality water effluent demand, climate conditions, substrate type and plants used. Therefore, the efficiency of the constructed wetlands that are designed and constructed according to the literature design parameters can be different then expected. The results of waste water treatment using a subsurface constructed wetland that is designed according to the literature data are presented. Experimental results and a mathematical model are described, and parameter estimation was conducted in order to determinate the reaction rate constant necessary for design of the constructed subsurface wetland that could be implemented in the continental area of Croatia. Achieved results indicate that a decrease of the constructed wetland area from 10 to 30% is possible.
