Macroalgal Population Explosion And Water Purification - Survey, Assessment And Prognosis

Abstract

Algal resources, their use and potential, have been investigated, but recent changes in marine benthic vegetation and the effects of eutrophication have also been using - the subject of investigation and concern. Solutions to these problems could lead to using, in some sites and under specific conditions, blooms in the prevention of further deterioration of coastal water quality. In addition, the urgent need to protect marine ecosystems may lead to the use of marine macrophytes as agents for tertiary waste-water treatment. Seaweeds are well suited for nitrogen-rich domestic and urban sewage purification, even for agricultural, fishpond and industrial polluted waters. A major impediment in implementing the encouraging results remains the economic benefit derived from such operations. In general, the operations remain, if not cost-prohibitive, then commercially non-profitable. Environmental and sustainability concerns may, in a not too distant future, override the lack of financial benefit.
