Liq. concn., diluting or filtering appts. - contg. semipermeable membrane forming part of elongated interior section in housing having specifically sealed cast end sections

摘要

An arrangement for concentrating, diluting, as well as filtration of liquids, gases or their mixtures by means of a semi-permeable membrane, whereby the membrane forms part of an elongated interior section which can be fitted into a housing, which is provided with cast sections in the region of opposite ends, whilst the cast sections are radially enclosed by cylindrical sealing surfaces. The housing has radially inward open grooves in the region of the sealing surfaces which are fitted with sealing rings sealably contacting the sealing surfaces. The sealing surfaces of the cast sections have two sealing rings at an axial distance from one another, whilst a clamping ring is fitted in that axial spacing. Both clamping rings attach the cast sections to the housing. USE/ADVANTAGE - The system can be used to concentrate, dilute as well as filter liquids, gases and their mixtures. The interior section can be readily interchanged. An elastic deformation of contacting surfaces is prevented.
