A treatment system combining the coal-based carbon membrane with electrochemical oxidation process was designed for the enhanced microalgae removal from simulated ballast water. The effects of various parameters including microalgae species, microalgae density, electric field intensity, and electrical conductivity on the separation performance were carried out. Fouling test was further performed for assessing the antifouling ability of the treatment system. The results showed big microalgae species tended to form a thick fouling layer on the carbon membrane, resulting in low permeate flux. High microalgae density gave rise to serious membrane fouling, which decreases the permeate flux. The treatment system showed enhanced permeate flux and fouling resistance by coupling with electrochemical oxidation process. High conductivity favored the electrochemical reactions on the surface of the carbon membrane, which reduces the clogging of the microalgae to the carbon membrane. After cleaning, the treatment system still kept high permeate flux, implying its good regeneration ability.
