Popis:	Performances of two-phase anaerobic treatments of wastewater containing cellulose using acidogenic-phase reactors combined with various membrane separation units was compared with those without membrane.By using a ceramic membrane module (pore size = 0.1 μm) submerged in a stirredtank reactor, almost all the cellulose and microbial cells could be retained in the reactor. The gas yield in this system was considerably greater than that in a stirred tank without membrane unit, even when treating a high C/N-ratio cellulose-waste-water.On the contrary, by using the membrane module immersed in a empty tube the accumulation of cellulose occured in the case of treating a high C/N-ratio wastewater. This low digestibility of cellulose was, however, improved by using a packed bedcolumn.
