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 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

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 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.

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. Read More

When the raw water is not flowing into the reverse osmosis membrane system, all remaining abnormal substances in the pre-treatment equipment that may accompany the flow of water should first be thoroughly removed before commissioning the equipment. Read More

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. Read More

With the widespread use of water purification equipment in the water treatment industry, reverse osmosis membranes are gradually gaining traction. The cost of reverse osmosis membranes is one of the main concerns of consumers. If done properly in the design, pre-treatment, daily maintenance and self-cleaning design of the reverse osmosis system, the service life of the reverse osmosis membrane can be extended and system operating costs greatly reduced. Good maintenance will help extend the life of the reverse osmosis membrane. Read More

In the process of using the equipment, in addition to the normal decay of performance, the decay of equipment performance due to pollution is more serious. The main types of contamination are chemical scale, organic and colloidal contamination, microbial contamination and so on. Different contaminants show different symptoms. The symptoms of membrane contamination also vary from one membrane company to another. Read More

With the development of the global economic level and the geometric growth of the population, modern industrial wastewater discharges, urban waste, rural pesticide spraying and so on have caused serious water pollution, so reverse osmosis technology is becoming more and more important and the application of reverse osmosis membranes is becoming more and more widespread. So do you know how many types of reverse osmosis membranes there are? Read More
