Description

Reverse osmosis membrane filter element for water purifying device

Technical Field

The utility model relates to a water purification filters technical field, specifically is a reverse osmosis membrane filter core for purifier.

Background

The reverse osmosis membrane is an artificial semipermeable membrane with certain characteristics and is a core component of the reverse osmosis technology, the principle of the reverse osmosis technology is that under the action of osmotic pressure higher than solution, other substances cannot permeate the semipermeable membrane to separate the substances from water, the membrane aperture of the reverse osmosis membrane is very small, so that dissolved salts, colloids, microorganisms, organic matters and the like in the water can be effectively removed, the system has the advantages of good water quality, low energy consumption, no pollution, simple process, simple operation and the like, when dilute solution (such as fresh water) and concentrated solution (such as saline water) with the same volume are respectively arranged on two sides of the semipermeable membrane, the solvent in the dilute solution naturally passes through the semipermeable membrane and spontaneously flows to one side of the concentrated solution, the phenomenon is called osmosis, when the osmosis reaches balance, the liquid level on the side of the concentrated solution is higher than the liquid level of the dilute solution by a certain height, that is, a pressure difference is formed, the pressure difference is an osmotic pressure, the magnitude of the osmotic pressure depends on the inherent properties of the solution, that is, the nature of the semipermeable membrane is related to the type, concentration and temperature of the concentrated solution, if a pressure greater than the osmotic pressure is applied to one side of the concentrated solution, the flow direction of the solvent is opposite to the original osmotic direction, and the solvent starts to flow from the concentrated solution to one side of the dilute solution, this process is called reverse osmosis, and is widely applied to the purification and concentration of various liquids, wherein the most common application example is to remove the impurities such as inorganic ions, bacteria, viruses, organic matters and colloids in the raw water by using the reverse osmosis technology in the water treatment process, so as to obtain high-quality purified water.
