| dc.description.abstract | the amount and particle size of dredged sediment besprinkled into water, and the amounts and types of additives. Results showed that the optimal amount of dredged sediment besprinkled into water was 0.6-1.6g/100mL. With decreasing particle size (< 100μm), Cochlodinium polykrikoides could be more efficiently removed. CaO and Ca(OH)₂ were found to be effective additives in promoting the removal efficiency. The optimal amount of additive was 10%. The removal efficiency of Cochlodinium polykrikoides was up to 99% when the dredged sediment(< 100μm) was besprinkled into water at the ratio of 1.6g/100mL. This result was comparable to that obtained with loess (95%). In the adsorption experiment of nutrients, on the other hand, the reaction was completed within 10 minutes using 100μM NO₃- and PO₄³-. In the steady state, 61% and 77% of 100μM NO₃- and PO₄³- were removed respectively. Adsorption isotherms of NO₃- and PO₄³- were suitable to the Freundlich equation. In addition, the adsorption reaction was not influenced by the ionic strength and pH. All the results in the present study showed that the dredged sediment from a coastal fishery could be successfully used as a substitute of loess for removing the red tide alga. | - |
| dc.description.abstract | In the present thesis, an experiment study has been performed to study the possibility of removing the red tide alga (Cochlodinium polykrikoides) and nutrients (nitrate and phosphate) using the dredged sediment from a coastal fishery. Experiments for removing Cochlodinium polykrikoides were conducted to derive the optimal conditions | - |
