  • How often should the reverse osmosis system be cleaned?

    2023-01-24

    1、How often should the reverse osmosis system be cleaned?In general, when the standardized flux decreases by 10-15%, or the system desalination rate decreases by 10-15%, or the operating pressure and differential pressure between segments increases by 10-15%, the RO system should be cleaned.Cleaning Read More
  • What Is The Difference Between Reverse Osmosis Ro Membrane And Nanofiltration Membrane Nf?

    2022-07-31

    Currently in water filtration, reverse osmosis membranes and nanofiltration membranes are the most commonly used membrane elements, but many users have a vague understanding of reverse osmosis membranes and nanofiltration membranes. Today Jun Xin will introduce to you what the differences between RO and NF membranes are, as well as the commonalities and differences. Read More
  • The Ro Membrane With Or Without Pores Debate

    2022-07-21

    The microstructure and filtration mechanism of reverse osmosis (RO) membranes, the most efficient filter membranes for contaminant retention, has been a hot topic of research. So, is an RO membrane a porous or non-porous membrane? The knowledge and answer to this question will have a direct impact on the understanding of the filtration mechanism of RO membranes. The answer to this question is changing with the advancement of technology and the deeper analysis of the microstructure of RO membranes. Read More
  • Proof Of Concept For Reverse Osmosis Technology

    2022-07-15

    The invention and large-scale application of Reverse Osmosis (RO) is a landmark achievement in the development of modern water treatment technology. As an advanced membrane separation technology developed after the 1950s, RO has been widely used in desalination, brackish water desalination, domestic water purification and wastewater reuse, etc. In 2018, more than 11 billion tonnes of desalinated water were produced worldwide using RO technology, which could be used by 320 million people. Over the past 70 years, many important scientists, entrepreneurs and a large number of technology companies have joined forces to perform a fascinating history of the development of reverse osmosis technology.

  • About Reverse Osmosis Desalination And Recovery Rates

    2022-07-14

    Reverse osmosis technology is currently the highest of all water production technologies mastered by mankind, through reverse osmosis components to improve the purity of water, cleanliness of almost 100%, to remove impurities and salt contained in the water. In the selection of reverse osmosis equipment, we are mainly concerned with two indicators: the desalination rate and the recovery rate, the former determines the quality of the water produced and the latter determines the utilisation rate of the water.

  • Why Should Scale Inhibitors Be Added To Reverse Osmosis Equipment?

    2022-07-13

    Reverse osmosis membrane is the key equipment of the reverse osmosis system, the system for a long time in continuous operation, the water calcium and magnesium plasma will be constantly precipitated and attached to the surface of the reverse osmosis membrane, the formation of scaling blocking the membrane pores, which will affect the efficiency of the reverse osmosis system water, damage to the reverse osmosis membrane. As the reverse osmosis membrane is more expensive, so in the operation of the system, to increase a section of the dosing system, water treatment equipment in the water with reverse osmosis scale inhibitor, delay the precipitation of calcium and magnesium ions and membrane surface scaling.
