Excessive
nutrient enrichment is the root cause of eutrophication, which as many
negative repercussions on aquatic systems. Although lakes and rivers
naturally receive nutrient input from their catchments and the atmosphere,
many human activities have accelerated and are accelerating the eutrophication problem through, for example, sewage inflows, runoff from
agricultural fields and industrial effluents. Some of the
symptoms include
excessive growths of algae (included cyanobacteria) and aquatic macrophytes.
Research was carried out to find a solution to the problem of
eutrophication.
The prevention of excessive input of the nutrients is hardly achievable
since most of it is from non-point sources and derives from many extended
sources.
Filtration of surface water could be an effective technique, but the
experimental result shows that it should be combined with further
treatments.
Ultrasonic irradiation has recently been considered as an alternative
solution to control algal blooming. Some devices using this principle
proved to be effective and are already on sale.
The problem
of eutrophication is still very actual and research
is still being
developed to reduce the water bodies’ pollution caused by algal growth.
