[News & Event] When is the anti pollution reverse osmosis membrane suitable for cleaning?

2024-11-11

When the reverse osmosis membrane element is confirmed to be contaminated, or before a long-term shutdown, or as a regular routine maintenance, it is recommended to clean the membrane element.

[News & Event] How to prolong the service life of industrial reverse osmosis membrane?

2024-08-18

Industrial reverse osmosis membrane is an important filtration consumable of water treatment equipment. Its filtration performance determines the water production effect of water treatment equipment. However, industrial reverse osmosis membrane belongs to consumables and has a certain service life. After a period of use, the performance will gradually decline and become unusable. So how can we extend the service life of industrial reverse osmosis membrane and effectively save investment costs?

[News & Event] How to clean household reverse osmosis membrane blockage?

2024-05-08

The RO reverse osmosis membrane plays a decisive role in the water purification process of the reverse osmosis water purifier. However, in the actual operation process, due to various reasons, the household reverse osmosis membrane will be blocked, causing the machine to fail to operate normally and affecting our daily drinking water. So, what are the main reasons for the blockage of the reverse osmosis RO membrane?

1. How many years can reverse osmosis membrane elements generally last?
The service life of reverse osmosis membrane elements depends on the chemical stability of the reverse osmosis membrane, the physical stability of the membrane elements, cleanability, influent water source, pretreatment, cleaning frequency, operation and management level, etc.

[Industry News] Industrial Wastewater Treatment Encyclopedia

2023-10-20

When it comes to industrial wastewater, many people don't have a clear concept. Most of us think that industrial wastewater is sewage discharged by some companies or enterprises. Strictly speaking, this definition is not accurate. Industrial wastewater refers to wastewater, sewage and waste liquid generated in the industrial production process, which contains industrial production materials, intermediates and products lost with water, and pollutants generated in the production process.

[Huamo College] Steps and precautions before and after installation of reverse osmosis membrane elements

2023-09-06

Reverse osmosis is a membrane separation operation that uses pressure difference as a driving force to separate solvent from solution. When pressure is applied to the feed liquid on one side of the membrane, when the pressure exceeds its osmotic pressure, the solvent will reversely penetrate in the opposite direction of natural osmosis. There are many things to pay attention to in the steps before and after the installation of the reverse osmosis membrane element. Let's take a look at the installation steps and precautions.

[Huamo College] What is nanofiltration membrane? How to prepare nanofiltration membrane？

2023-02-19

Nanofiltration membrane is also called ultra-low pressure reverse osmosis membrane. The membrane with a molecular weight cutoff of 200-1000 and a NaCl retention rate of ≤90% can be considered as a nanofiltration membrane. Nanofiltration membrane separation technology has been separated from reverse osmosis technology and has become an independent separation technology between ultrafiltration and reverse osmosis technology.
