【Abstract】 The function and efficiency of the new generation of green biocide--EGD in the control of biofouling caused by mussels was tested, while the simulated direct-current seawater cooling system and drug-adding mode were employed. It is indicated that the EGD is toxic to adult mussels. When the drug is added at the concentration of 10 mg/L intermittently, the mortality ratio of mussels was 38% after 30 days. Thus, the EGD can effectively restrain the development of mussels thereby prevent the biofouling. The EGD is an environmental-friendly biocide whose optimal dose is related to the wet-surface area of the water system.更多还原
