Abstract

The invention discloses a sufficiently filled integrated RO (Reverse Osmosis) membrane. The integrated RO membrane is composed of an RO membrane element which is flatly cut by water collection pipes at two ends, an inner connection connector and a shell; the inner connection connector is assembled to water production ends of the water collection pipes for flatly cutting the RO membrane; one relatively thin end of the inner connection connector penetrates through a reserved hole in the shell; a cover is welded onto the shell. The integrated RO membrane provided by the invention can efficiently utilize a space in the shell, and the effective length of the RO membrane assembled in the integrated membrane is the greatest under the condition that the length of the shell is the same.
