Supporting the widespread adoption of water treatment membrane technology

Membrane separation technologies such as reverse osmosis, nanofiltration and ultrafiltration have become core processes in industrial water treatment, municipal water supply, seawater desalination and ultra-pure water preparation. Specialized chemicals for membranes are the key to ensuring the stable operation of membrane systems, extending their service life and reducing operating costs. Recently, the technologies of a series of products such as high-efficiency membrane scale inhibitors, membrane cleaning agents, membrane protectants, and reducing agents have been continuously maturing. With features like high purity, low pollution, and high adaptability, they have promoted the large-scale application of membrane technology in more fields.
During operation, the membrane system is prone to contamination by calcium and magnesium ions, silicides, iron and manganese ions, microorganisms, etc., which leads to a decrease in membrane flux, an increase in pressure difference, and a reduction in desalination rate. The dedicated membrane scale inhibitor effectively inhibits the crystallization and deposition of insoluble salts on the membrane surface through dispersion and chelation, keeping the membrane channels unobstructed and extending the cleaning cycle. For different types of pollution, acidic, alkaline and biofilm-specific cleaning agents can gently and efficiently remove contaminants on the membrane surface, restore membrane performance, and at the same time reduce damage to the membrane material.
In the field of seawater desalination, salt-resistant membrane scale inhibitors can adapt to water with high salinity and hardness, ensuring the stable operation of the system and reducing water production costs. In electronic ultrapure water and power plant boiler feed water systems, high-purity membrane chemicals can prevent secondary pollution and ensure that the produced water quality meets the standards. In industrial wastewater reuse projects, the combination of membrane chemicals and membrane systems can increase the wastewater reuse rate to over 85%, achieving the recycling of water resources.
