This invention relates to a dual-layer, multifunctional hollow fiber membrane having at least two layers that perform two respective functions: 1) a layer that performs a separative function separating a solvent such as a liquid or gas from its solute species; and 2) a layer that performs the function of generating a magnetic field. The layer generating the magnetic field preferably has magnetic nano or micro particles embedded therein to attract, capture and/or position paramagnetic draw solute particles to maximize their osmotic effect.

The invention provides a system for sanitizing fluids such as water and air. In particular, the invention provides a combination of solid chlorhexidine and a polymer matrix, for which effluents are essentially free of leached chlorhexidine. The systems enable rapid disinfecting of fluids, including in line at the point of use, and can be employed for both high volume applications and disposable single-use applications.

A polymerizable composition for forming an ion-exchange resin precursor, the polymerizable composition containing a monomer component and polyethylene particles in an amount of 50 to 120 parts by mass per 100 parts by mass of the monomer component, wherein the monomer component contains an aromatic monomer for introducing ion-exchange groups and a nitrogen-containing aliphatic monomer, the nitrogen-containing aliphatic monomer being present in an amount of 10 to 35% by mass in said monomer component. An ion-exchange membrane is produced by applying the polymerizable composition onto a polyolefin type filament base material and polymerizing the polymerizable composition to form an ion-exchange resin precursor and, thereafter, introducing ion-exchange groups into the precursor.

A device for decomplexation and enhanced removal of copper based on self-induced Fenton-like reaction constructed by electrochemistry coupled with membrane separation is disclosed. The device includes a reactor, two electrocatalytic anodes capable of generating hydroxyl radicals, an electrocatalytic cathode membrane assembly, a direct current power supply, an aeration system, an inlet pipe and an outlet pipe.
