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

From that time, all types of shopping centres were built, starting from the very basic first generation and developing into the most current formats. In the article, types of shopping centres are compared to their western origins. Planning laws and procedures that apply to the processes are also described, with an example of a law that was introduced to specifically control growth of shopping centres. Apart from that current trends and growth possibilities in the present market situation are discussed. As a result, a very rapid development process was observed, with little hampering from the planning policies. This may be used as a point of reference for other countries that have not yet encountered that process.展开更多
