Potential application of nanotechnology for water treatment in ornamental aquatics culture systems

At present, the ornamental fish aquaculture and edible fish aquaculture are growing, and this requires the high consumption of water in culture systems aimed at breeding and cultivation of this group of aquatic animals. Considering, the limitations of water resources, sustainable development of ornamental fish aquaculture requires saving and minimizing water consumption. One of the effective strategies to reduce water consumption and reuse, is water treatment. Nanotechnology has grown over the past years in all aspects of science and industry. Due to the efficiency of nanotechnology and the diversity of its methods of use, it can be widely used in treatment of water in culture systems. In this paper, various methods of using nanotechnology in wastewater treatment, with emphasis on carbon nanotubes, have been investigated.
