Description

Reverse osmosis membrane element

Technical Field

The utility model relates to a reverse osmosis membrane element.

Background

The reverse osmosis membrane is an artificial semipermeable membrane with certain characteristics and is made by simulating a biological semipermeable membrane, and is a core component of a reverse osmosis technology. The principle of reverse osmosis is that under the action of the osmotic pressure higher than that of the solution, other substances are separated from water based on the fact that the substances cannot permeate a semipermeable membrane. The reverse osmosis membrane has a very small membrane pore size, and thus can effectively remove dissolved salts, colloids, microorganisms, organic substances, and the like in water. The system has the advantages of good water quality, low energy consumption, no pollution, simple process, simple and convenient operation and the like.

The reverse osmosis membrane is a core element for realizing reverse osmosis and is an artificial semipermeable membrane with certain characteristics and made by simulating a biological semipermeable membrane. Generally made of high molecular materials. Such as cellulose acetate films, aromatic polyhydrazide films, aromatic polyamide films. The diameter of the surface micropores is generally between 0.5 and 10nm, and the size of the permeability is related to the chemical structure of the membrane. Some polymer materials have good salt repellency, but the water permeation rate is not good. Some polymer materials have more hydrophilic groups in their chemical structures, so that the permeation rate of water is relatively fast. A satisfactory reverse osmosis membrane should therefore have a suitable permeate or salt rejection.

The reverse osmosis membrane unit is one kind and uses reverse osmosis membrane to realize water filtration's equipment as the carrier, is used for the water purifier more, and reverse osmosis membrane unit equipment is comparatively troublesome among the prior art, and after the inside filth in later stage, it is comparatively difficult to clean, therefore most of reverse osmosis membrane units among the prior art all are disposable article, and use cost is higher relatively.

Therefore, we have designed a reverse osmosis membrane element that is simple to assemble and easy to clean internally.
