What is the difference between softened water equipment and pure water equipment?

At present, there are various types of water treatment equipment on the market, including distilled water machines, softened water equipment, sterile water equipment, pure water machines, etc., which are suitable for the production and processing of food, beverages, medicine, etc. Treat with water. Among them, softened water equipment and pure water equipment are often used to reduce water hardness, and use reverse osmosis membrane technology to make most of the inorganic salts (including heavy metals), organic matter, bacteria, viruses, etc. dissolved in the water unable to pass through the reverse osmosis membrane. And effectively separate it from water molecules and ionic mineral elements.

So, what are the specific differences between softened water equipment and pure water equipment? According to reports, since the hardness of water is mainly formed and expressed by calcium and magnesium, water softening equipment can mainly remove calcium and magnesium ions in the water to achieve the softening effect of the water, so as to avoid a large amount of scale produced by long-term use of unsoftened water. Affect water quality and safety. However, water softening equipment cannot reduce the total salt content in the water during the process of softening water. It can be used to soften industrial water supply water and treat domestic water.

Regarding pure water equipment, the author learned that this equipment mainly uses reverse osmosis membrane technology. Through the reverse osmosis membrane, water molecules and ionic mineral elements can be separated from other water. Most inorganic salts, organic matter, bacteria, viruses, etc. are separated, thereby effectively separating the permeated pure water from the impermeable concentrated water. At present, pure water equipment has not only been vigorously developed in industries such as food and beverage, drinking water, pharmaceuticals and surface cleaning, but is also widely used in wastewater treatment, microorganisms and other fields.

It is not difficult to see from the above that water softening equipment mainly softens water and has no purification effect. In comparison, pure water equipment can separate organic matter, bacteria, microorganisms, etc., and can purify water. In addition, in terms of equipment classification, there are relatively many types of softened water equipment, including manual type, automatic type, fully automatic type, vertical valve fully automatic type, etc., while ultrapure water equipment is often seen in pure water equipment, which uses The reverse osmosis method for producing high-purity water has become popular.

In addition, from the perspective of operation process, the workflow of softened water equipment generally goes through multiple processes such as backwashing, salt absorption (regeneration), slow flushing (replacement), and fast flushing. Any water softening equipment based on sodium ion exchange is mostly based on this workflowDeveloped on the basis of the process. However, it should be mentioned that fully automatic water softening equipment will increase the brine refilling process. It is understood that ultrapure water equipment preparation processes are roughly divided into five types, and the last four processes are also developed on the basis of traditional processes.

According to a manufacturer, the traditional process mainly includes pretreatment system, reverse osmosis system, intermediate water tank, rough mixing bed, fine mixing bed, pure water tank, pure water pump, and ultraviolet sterilizer , polishing mixed bed, precision filter, etc. With the rapid development of pure water equipment preparation technology, EDI devices, second-stage reverse osmosis, etc. have been added to the original ones. Nowadays, many new processes have replaced traditional processes, and the reverse osmosis method for producing high-purity water has become popular, greatly improving the quality of pure water.

Softened water equipment and pure water equipment are experiencing rapid development in the domestic food and beverage, drinking water and other industries. Today, when the quality and safety of food and beverages have attracted much attention, they will also usher in a better future. development space. Industry insiders believe that “Although softened water equipment and pure water equipment are both types of water treatment equipment, there are certain differences in their principles, functions and operating processes. With the continuous development of science and technology, softened water equipment and pure water equipment The comprehensive performance should also be improved to ensure the quality and safety of water for food, beverages, drinking water, etc.
