Abstract

This study was carried out to evaluate aquaculture by-products, abalone and oyster shell, as sediment amendments and compare their efficiency with those of commercially available products. It was revealed that four remediation materials could effectively lower the COD and AVS of organically enriched sediment mainly by dilution effect. Moreover, remediation materials made of abalone or oyster shell showed as similar remediation efficiency as compared with commercial amendments. It also suggested that in order to reduce COD and AVS to the level of 90% of original concentration, any of four remediation materials could be applied with the amount of 10~40 kg to square meter of organically enriched sediments.
