A method for removing silica from ultra pure water (UPW) comprises passing UPW through a filter comprising a microporous cationically charged membrane having an upstream surface and a downstream surface; and a porous asymmetric membrane having a first surface and an upstream portion and a downstream portion and a second surface, and a bulk between the first surface and the second surface including the upstream portion and the downstream portion, the porous asymmetric membrane having decreasing pore sizes in a direction from the first surface and the upstream portion to the downstream portion and the second surface, the second surface comprising a skin having a nanoporous average pore size, wherein the first surface of the porous asymmetric membrane contacts the downstream surface of the microporous cationically charged membrane; the method including passing the UPW through the microporous cationically charged membrane before passing the UPW through the porous asymmetric membrane.

A corrosion-resistant cover system, having a corrosion-resistant cover structured and configured to be arrangeable around an object having one or more metallic surfaces that are susceptible to corrosion. The corrosion-resistant cover is operable to provide increased corrosion resistance to the object by preventing contact between the one or more metallic surfaces and ambient conditions exterior to the corrosion-resistant cover.

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.
