How much do you know about ultrafiltration technology and ultrafiltration membranes? Ultrafiltration membrane technology is an important technology for water treatment in environmental protection projects. It has extremely broad application prospects in urban sewage treatment, various industrial wastewater treatment, and recovery of useful substances. At present, one of the research directions of ultrafiltration membrane technology is to invent more efficient ultrafiltration devices, and the other is to combine it with other water treatment technologies based on the characteristics of the incoming water quality to improve the quality of the effluent.
Reverse osmosis is a water treatment process that developed rapidly in the 1960s. At present, it has been used in urban water, boiler feed water, power plant boiler feed water, industrial wastewater, seawater desalination, and solute separation in various solutions. The working principle of the reverse osmosis membrane is to use pressure as a driving force to separate the solvent from the solution. It has good applications in food, electronics, medicine, printing and dyeing and other industries. In the long-term use process, some problems are inevitable. How are some of the "phenomena" that appear in the application of reverse osmosis membranes formed?
Water purifiers are becoming more and more common nowadays. Many people want to buy water purifiers but don’t know where to start. If they buy without any advice, they will be easily overwhelmed by a lot of technical terms used by the salesperson. Today, I will tell you what these terms mean and how to “pick” the RO reverse osmosis water purifier that suits you best! Let’s read on.
Water purifier filter element analysis and recommendations
In the current market, there are many types of water purifiers, with prices ranging from a few hundred yuan to several thousand yuan. For ordinary families, how to choose a water purifier that is both economical and affordable and can effectively filter pollutants in the water has become a key issue. In this article, Susan will help you understand several common water purifier filter technologies and their pros and cons, and focus on analyzing the cost performance of low-priced water purifiers to help you make a wise choice.
When buying a water purifier, I believe everyone has heard of "RO membrane filter" or "reverse osmosis membrane filter", but some friends don't quite understand what it means.
We also call the pure water machine reverse osmosis RO water purifier. From this name, we know the significance of RO membrane to the pure water machine. Its existence makes the pure water machine worthy of its name and can filter out pure water for direct drinking.
So do you know what RO membrane is? Next, Susan will take you to explore it together.
If the hollow fiber membrane is the three thousand strands of troubles, the reverse osmosis membrane is the core with thousands of knots. The common voice of the membrane masters: "Magic mirror, magic mirror, tell me, why is the reverse osmosis membrane blocked again?"
Reverse osmosis membrane: "Guess!"
Reverse osmosis membrane is the "soft girl" among membranes, very delicate and fragile. When the grid, biochemical, and ultrafiltration have blocked most of the pollutants and the water is already very clean, whether we block it or not depends on our mood.
The joke is over, let's get back to the topic, and here is a summary of the reasons why the reverse osmosis membrane is blocked:
Hello everyone, I'm Susan~ Today we're going to talk about a topic that every household is concerned about - tap water pollution and the role of water purifiers. Did you know? During the transportation process, tap water may encounter secondary pollution, including heavy metal pollution, excessive fluoride, plastic particle pollution and other problems. Oh, does it sound a bit scary? Don't worry, let's take a deeper look.
