Abstract:

In recent years, studies about the protection of wetlands have growing importance in our country. Therefore, detection of all pollutant sources which enter to surface waters and/or lakes is needed. Particularly wastewaters are discharged to surface waters and/or lakes in most regions. This causes increase of C, N, P which present in wastewater in water environment. As a result of this, the increase of nutrient causes pollution and effects the aquatic ecosystem negatively. Today, for the elimination of this problem, several methods are used for nutrient removal from wastewaters. Nurtient removal is achieved by using ducweed as Lemna gibba L, Lemna minor L., Spirodela polyrrhiza and Wolffia arrhiza. In our country ducweed can be used for nutrient removal because of their properties like accessibility in our country, high removal capasities, resistance to the negative conditions, being economical.
