A Simple and Cost-Effective Method for Fabricating Chitosan-Filled Filter Media from Lignocellulosic Biomass

Abstract:

The newly developed non-woven filter media are composed of randomly oriented fibrous fibers from lignocellulosic biomass. The aim of this study is to investigate the feasibility of incorporating chitosan solution in fibrous filter media made from lignocellulosic biomass. The wet lay-up method was adopted for filter media fabrication. Diluted acetic acid was used as medium to dissolve the chitosan powder. Chitosan solution was applied to the fiber using two different deposition techniques, namely, spray method and addition method. The tensile test demonstrated that the filter media using spray method outperformed a filter media made from by addition technique. From the FT-IR spectrum, when the chitosan was added to empty fruit bunches fibers, the absorption peaks at around 1642 cm^-1 are clearly identified that showing the presence of amine group in the fibers. The changes observed in the spectra indicated the possible interaction of functional groups between chitosan and cellulose in the fibers. The newly developed non-woven filter media integrates the functions for both the deep filtration and mechanical screen, thus it will be an alternative medium in oily wastewater treatment industry.
