抄録

Filtration experiments were conducted using the double layer membrane consisted of the microfiltration membrane and the activated carbon membrane. Such separation properties as the filtration rate and the rejection were examined using silicon dioxide suspensions containing phenol. The double layer membrane was found to be quite efficient for the separation of the particulate suspensions including the dissolved organic matter. The silicon dioxide particles were rejected by the sieve effects of the microfiltration membrane, whereas phenol was rejected by the adsorption effects of the activated carbon membrane. High phenol concentration caused the reduction of the phenol rejection as filtration proceeded. Although the filtration rate increased with the increase of the filtration pressure, the phenol rejection in the incipient stage of filtration became relatively small under high pressure conditions. It was also shown that the adsorption rate obtained in filtration experiments was significantly larger than that in static adsorption experiments.
