| Summary: | Due to their simplicity and low operation cost, constructed wetlands are
becoming more prevalent in wastewater treatment all over the world. Their
range of applications is no longer limited to municipal wastewater but has
expanded to the treatment of heavily polluted wastewaters such as
agro-industrial effluents. This paper provides a comprehensive literature
review of the application of constructed wetlands in treating a variety of
agro-industrial wastewaters, and discusses pollutant surface loads and the
role of constructed wetland type, prior-treatment stages and plant species in
pollutant removal efficiency. Results indicate that constructed wetlands can
tolerate high pollutant loads and toxic substances without losing their
removal ability, thus these systems are very effective bio-reactors even in
hostile environments. Additionally, the review outlines issues that could
improve pollutant treatment efficiency and proposes design and operation
suggestions such as suitable vegetation, porous media and constructed wetland
plain view. Finally, a decision tree for designing constructed wetlands
treating agro-industrial wastewaters provides an initial design tool for
scientists and engineers. |
