Composite semi-permeable membrane |
| abstract |
The object of the present invention is to provide a composite semipermeable membrane which has high treatment efficiency even in a drainage process which is likely to be clogged due to a large amount of contaminants and which is unlikely to lower the treatment efficiency even in a pressure raising operation accompanying high-pressure continuous use. The present invention provides a composite semipermeable membrane having a polymer porous layer on one side of a nonwoven fabric layer and a polyamide based separating functional layer on the polymer porous layer, wherein the ratio of the thickness of the polymer porous layer to the thickness of the non- 0.45. |
