     a novel configuration of microbial desalination cell (mdc) packed with ion-exchange resin (r-mdc) was proposed to enhance water desalination rate. compared with classic mdc (c-mdc), an obvious increase in desalination rate (dr) was obtained by r-mdc. with relatively low concentration (10–2 g/l nacl) influents, the dr values of r-mdc were about 1.5–8 times those of c-mdc. ion-exchange resins packed in the desalination chamber worked as conductor and thus counteracted the increase in ohmic resistance during treatment of low concentration salt water. ohmic resistances of r-mdc stabilized at 3.0–4.7 ω. by contrast, the ohmic resistances of c-mdc ranged from 5.5 to 12.7 ω, which were 55–272% higher than those of r-mdc. remarkable improvement in desalination rate helped improve charge efficiency for desalination in r-mdc. the results first showed the potential of r-mdc in the desalination of water with low salinity.
