Hollow-fiber membrane device and method for the production thereof

Abstract

The group of inventions relates to technologies for purifying liquid, primarily water for the domestic and/or drinking water supply in domestic and/or industrial conditions and in allotments and gardens. The characterizing feature of the group of inventions is that the design of a hollow fibre membrane device envisages, and a method for the manufacture thereof enables, the formation of a protective layer consisting of a single polymeric fixing material on the internal surfaces of mono-fibre sections which are incorporated into a binding unit, and the formation of sections which are in the form of a composite in the binding unit, which increases the strength of the hollow fibre membrane device, wherein open channels in the binding unit, formed with the aid of protective elements of an assembly base, make it possible to increase the specific filtering surface. The general problem addressed by the group of inventions, and the technical result which can be achieved with the use of the group of inventions, consists in creating a design of a hollow fibre membrane device and in developing a method for producing the design of the device, making it possible to increase the strength characteristics of the hollow fibre membrane device while simultaneously increasing the specific filtering surface.
