Constructed floating wetlands mediated nutrient management of eutrophic lakes

Abstract

Eutrophication is the process of enrichment of water source due to excess of nutrients or organic matter that promotes primary production owing to the growth of algae and other plants and also reduce total dissolved oxygen. It is a concern as it has numerous negative impacts not only on ecology but also aesthetically, recreationally and economically. Constructed floating wetlands have been recognized as effective mechanisms for water treatment. They are engineered system designed to enhance the interaction that occurs in natural wetlands between water, plants, microbes, soil and atmosphere in order to remove pollutants from water in a more natural and passive manner. If Constructed Floating wetlands are able to reduce nutrient load of eutrophic water then they can be implemented to restore the conditions of various lakes, which are suffering with contamination by point and non-point sources of pollution. Predominantly, these floating wetlands themselves being eco-friendly can be extremely successful in reinvigorating animal populations and providing natural beauty in areas that are otherwise lacking.
