Membrane element High water yield
Introduction:Reverse osmosis membranes are artificial semi-permeable membranes with certain characteristics that mimic biological semi-permeable membranes and are the core building blocks of reverse osmosis technology. The principle of reverse osmosis technology is that other substances cannot pass through a semi-permeable membrane under the effect of an osmotic pressure higher than that of the solution, and these substances and water are left behind.

Features
1. High Filtration Precision：Reverse osmosis membranes can achieve extremely high - precision filtration. They are capable of removing a wide variety of contaminants, including dissolved salts, heavy metals, bacteria, viruses, and organic molecules with high efficiency. For example, they can reject over 99% of dissolved salts, effectively purifying seawater into potable water. This high - precision filtration is crucial for applications where pure water is required, such as in the pharmaceutical industry, semiconductor manufacturing, and high - end drinking water production.
2. Good Chemical Stability：These membranes have excellent chemical stability. They can withstand the influence of various chemical substances in the feed water, such as acids, alkalis, and oxidants within a certain range. This allows them to be used in different water treatment scenarios. For instance, in industrial wastewater treatment, reverse osmosis membranes can still maintain stable performance when dealing with wastewater containing certain chemical pollutants, ensuring reliable water treatment results.
3. High Permeability：Reverse osmosis membranes possess high water permeability while maintaining high rejection rates for contaminants. This means they can allow a relatively large amount of water to pass through in a unit of time under a certain pressure, improving the water treatment efficiency. For example, in large - scale desalination plants, high - permeability membranes can significantly increase the daily water production capacity, meeting the water demands of large populations or industries.
4. Long Service Life：With proper operation and maintenance, reverse osmosis membranes can have a relatively long service life. Their stable structure and performance enable them to continuously function effectively for an extended period. For example, in a well - maintained water treatment system, reverse osmosis membranes can last for 3 - 5 years, reducing the frequency of membrane replacement and lowering the overall cost of water treatment.
Working Principle
1. Osmosis Principle Basis：The working principle of reverse osmosis is based on the osmosis phenomenon. Osmosis is a natural process where water molecules move from an area of lower solute concentration to an area of higher solute concentration through a semi - permeable membrane until an equilibrium is reached. For example, if a semi - permeable membrane separates a pure - water side and a salt - water side, water molecules will flow from the pure - water side to the salt - water side.
2. Reverse Osmosis Process：Reverse osmosis is the opposite of the natural osmosis process. When a pressure greater than the osmotic pressure is applied to the side with a high - solute concentration (such as salt - water), water molecules are forced to flow from the high - solute - concentration side through the reverse osmosis membrane to the low - solute - concentration side (pure - water side). The reverse osmosis membrane has extremely small pores that allow only water molecules to pass through while blocking the passage of larger solute particles, such as dissolved salts, bacteria, and organic molecules.
