Membrane element lefilter

Membrane element

Reverse osmosis membrane is an artificial semipermeable membrane with certain characteristics made by simulating biological semipermeable membrane,and it is the core component of reverse osmosis technology.The principle of reverse osmosis technology is that with the action of higher than the osmotic pressure of the solution,these substances and water are separated according to the fact that other substances cannot pass through the semi-permeable membrane.

Application Mainly used in reverse osmosis pretreatment,drinking water treatment,reclaimed water reuse and other fields.
Filter media Molecular substances such as suspended solids,colloids,proteins and microorganisms in solution.

Working principle

Reverse osmosis is the process of applying a pressure greater than the osmotic pressure of the solution on the concentrated solution side,forcing water molecules to pass through the semipermeable membrane in the reverse direction (opposite to the natural osmosis direction) into the dilute solution.The semipermeable membrane flows to dilute solutions,while most of the solutes (dissolved solids) cannot pass through the membrane and are trapped.Therefore,the concentrated solution is further concentrated or dehydrated, and the dilute solution is diluted and purified or desalted.

Membrane element working principle


  • Membrane element advantage

    Membrane element
    The filtration precision can reach 0.0001 micron,and it is filtered by RO membrane,which can strongly filter out bacterial impurities,heavy metals.


    Original import:

    complete documents, first-class agent

  • Membrane element advantage

    The reverse osmosis membrane has the characteristics of good water quality,low energy consumption,no pollution,and simple operation,it’s widely used in the fields.


    Good stability:

    It has high mechanical strength and service life,and can function at lower operating pressures.

  • Membrane element advantage

    Less affected by factors such as pH, temperature, etc., and can function at lower operating pressures.

    Small hole

    The reverse osmosis membrane with a filtration accuracy of 0.0001 microns can intercept substances larger than 0.0001 microns.It is the finest membrane separation product.It can effectively intercept all dissolved salts and organic substances with a molecular weight greater than 100.

  • Membrane element advantage

    Large throughput,anti-pollution,easy to clean,precise definition,can meet the needs of various industries.


    The equipment is easy to use:

    Modular design,easy to install,it can reduce the cost of water and sewage,can be integrated with existing membrane filtration system or ion exchange system to achieve up to 80% of the rinse water cycle.
