Abstract

Appts. includes an inlet at one end, for the liquid to be treated, and an outlet at the other end for the treated liquid, >=1 pipe being connected to the spirally wound membrane for discharging the fluid which passes through the membrane. The tubular mandrel is specif. divided into two parts by a central plug, the first part having an outlet for the fluid to be treated and the second part an opening for the passage of the treated fluid which has traversed the membrane.
