초록

This study was conducted to investigate the feasibility of using positively charged torrefied wood flour (TWF) from an damaged wood by pest for raw material of pellet and particle boards. The positively charged torrefied wood flour was evaluated for zeta potential to measure surface charge, removal efficiency of turbidity, optical density, chlorophyll-a, PO4-P as algal bloom remover. The zeta potential of the algal bloom was negatively charged. But The samples prepared through the surface modification treatment exhibited a positive zeta potential of -0.2 mV ~ 31.2 mV. The addition of positively charged torrefied wood flour reduced the turbidity from 83.8 ntu at the initial time to 10 ntu after 8 hours. Optical density results were similar to turbidity. The removal rate of chlorophyll-a was 92% after 8 hours. The removal rate of dissolved phosphorus, which is a cause of algal bloom, was 6.5% for activated carbon and 10% for TWF C-PAM 3 wt%. Therefore, the usefulness as algal bloom remover was confirmed through the results of the removal rate turbidity, optical density, chlorophyll-a, and PO4-P.
