Osmosis membrane assembly for dielectrophoresis forward-osmosis flat plate

Abstract

The invention relates to an osmosis membrane assembly for a dielectrophoresis flat plate. The osmosis membrane assembly comprises a flat plate framework, electrodes and an osmosis membrane, and is characterized in that the flat plate framework is manufactured from ABS (Acrylonitrile-Butadiene-Styrene); uniformly distributed electrodes are transversely embedded in the flat plate framework at intervals; an osmosis membrane is arranged in the flat plate framework in a penetrating manner; a water inlet is formed in the water inlet end of the flat plate framework; an electric wire output port and a water outlet are formed in the water outlet end of the flat plate framework; the water inlet is connected with the water outlet in a penetrating manner through a water channel inside the flat plate framework; the electric wire output port is connected with the electrodes of the flat plate framework, and is lead out to be connected with an external power supply. With the dielectrophoresis technology, according to the difference of dielectric polarization capabilities of solid particles and suspended liquid, dielectric electrophoretic force is used for pushing the solid particles to be away from the electrodes or absorbing the solid particles on the electrodes, and thus the concentration polarization caused by water flowing to a driving liquid side from a raw material liquid side in the separation technology of forward-osmosis flat plate membrane is slowed down or even prevented so as to strengthen the forward-osmosis technology.

Description

technical field [0001] The invention belongs to the technical field of separation, and relates to a permeable membrane filtration separation process, in particular to a dielectrophoresis forward osmosis plate permeable membrane component. Background technique [0002] In 1748, the Frenchman Abble Nollot discovered the phenomenon of osmosis. From then on, the phenomenon of osmosis has aroused great interest of people. Forward osmosis (FO), also known as osmosis, refers to the process in which water or other solvents pass through natural or artificial semipermeable membranes and pass from the side with low solute concentration to the side with high solute concentration. a physical phenomenon. The characteristic of forward osmosis technology is that its driving force is the chemical potential difference or osmotic pressure difference itself of the two solutions, without external pressure. Utilizing the property of water spontaneously passing through the selective semi-permeab...

Problems solved by technology

[0005] As a result of concentration polarization, the effective osmotic pressure difference on both sides of the membrane decreases, and thus the driving efficiency decreases, which is the key factor affecting the decrease of membrane flux.
