Abstract

Eutrophication, which kills fish, mussels and other animals in aquatic ecosystem, is the response to
the excess of nitrogen and phosphorus nutrients. In this study, activated carbon fiber prepared from
poly(acrilonitrile) PAN, a carbonaceous material of micro size with high specific area, has been evaluated to
be able to create microbiological membranes that could be used in the decomposition of nitrogen and phosphorus
compounds in wastewater with salinity up to 30 ppt. Utilization of carbon fiber in the sustainable
treatment of highly contaminated aquaculture wastewater with organic and inorganic pollutants was considered
as a promising application in Khanh Hoa province, Vietnam, with great treatment capacity, low system’s
price and implementation’s cost.
