PTFE (Polytetrafluoroethylene, trade name "Teflon", commonly known as "King of Plastics") was discovered in 1932 by Dr. Roy Plunkett, who came to the United States after graduating from DuPont to work on organic fluorine. In the summer of 1938, he discovered the white powder polymer polytetrafluoroe Read More

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.

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

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
