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

Reverse osmosis membranes are now used in a wide range of industries, but do you know their origins and history? This article takes you through the history of reverse osmosis membranes. Read More

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.

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.

For each membrane unit, people want it to function to the maximum, hoping for the highest desalination rate, maximum water permeability and the longest possible life. A reasonable pre-treatment is essential for the long-term safe operation of the reverse osmosis plant. Read More

In system operation, membrane contamination is a very difficult problem, which causes a significant decrease in the removal rate and water permeability of the reverse osmosis unit and membrane flux, as well as increasing the operating pressure of each section and contributing to higher operating and operational costs, which seriously affects the service life of the membrane and the development and utilization of reverse osmosis technology.

Reverse osmosis equipment is easy to operate and its high efficiency saves money in various areas such as manpower. However, some problems inevitably occur in the daily operation of reverse osmosis equipment, so in order to extend the service life of reverse osmosis equipment, the operator should not only have certain maintenance skills, but also the daily data of reverse osmosis equipment is particularly important to record.
