Abstract
A reverse osmosis permeator of the capillary type wherein the tube sheet in which the ends of the capillaries are mounted and the porous support block therefor are slidably mounted on a hollow feed tube mounted in the center of the permeator is disclosed. The invention involves insuring that relative movement between the tube sheet and the support block does not occur during shut down of the permeator. This can be done by hydraulic pressure, spring loading, or mechanical attachment such as one or more bolts.
