Micro-sized carbon fiber: a new supporting material for microorganisms in the decomposition of nitrogen and phosphorus nutrients in wastewater with high salinity

Abstract

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