Ultrapure water equipment
Pure water equipment
In recent decades, < r>Mixed bed ion exchange Technology
has always been the standard process for the preparation of ultrapure water. Since it requires periodic regeneration and uses a large amount of chemicals (acid and alkali) and pure water during the regeneration process, which causes certain environmental problems, it is necessary to develop an acid-base-free ultrapure water system.
Precisely because traditional ion exchange has become increasingly unable to meet the needs of modern industry and environmental protection, the technology that combines membrane resin with electrochemical principles has become a revolution in water treatment technology. The regeneration of its ion exchange resin uses electricity instead of acid and alkali, so it is more satisfied with the environmental protection requirements of today's world.
Since the industrialization of membrane stack technology in 2008, thousands of systems have been installed around the world. It has been vigorously developed especially in industries such as pharmaceuticals, semiconductors, power and surface cleaning, and has also been developed in fields such as wastewater treatment, beverages and microorganisms.

Principle of ultrapure water equipment
< r>Ultrapure water equipment
Water treatment that uses pretreatment reverse osmosis technology mixed bed device and post-treatment methods to almost completely remove the conductive medium in the water, and remove the non-dissociated colloidal substances, gases and organic matter in the water to a very low level. equipment. Ultrapure water equipment is also called: ultrapure water device, ultrapure water machine, ultrapure water meter, ultrapure water system, laboratory ultrapure water device, etc. The resistivity of the ultrapure water produced by the ultrapure water machine should generally be greater than megohms, and water above megohms is called ultrapure water. Generally, the output of ultrapure water can reach megaohms.
