This can be done through process changes, or by adding a finishing treatment after the process, like flotation or filtration. Wetlands are also one possibility for the finishing treatment of waste water. In Finland Wetlands have been used as a polishing treatment for municipal wastewater for approx. 20 years. Most of these are natural wetlands. Using wetlands after efficient wastewater treatment is an economical way of producing high quality treated water and cutting down the pollution load of water bodies. Wetlands have also been used in the control of diffuse pollution in agriculture and forestry.展开更多
