FIELD: process engineering.
SUBSTANCE: invention relates to filtration module and may be used in water treatment as a component of reverse osmosis plant and in gas filtration. Filtration module has pressure tube to house membrane with unboiled water feed branch pipe and filtrate and residual fraction discharge branch pipes. Functional/connection unit with top and bottom parts is jointed to pressure tube end. Branch pipes are arranged on top part. Through channels communicated with said branch pipes extend through bottom part. Note here that exposed annular space is provided between pressure tube and membrane. Fluid feed through channel terminates in said bottom part annular gap wherefrom fluid flows into annular space.
EFFECT: invention rules out stagnant spaces, easier replacement of membrane.
