1、 Introduction to large-scale industrial softened water equipment:

Industrial softened water equipmentAlso known as water softening device, water softener, water softener, water softening equipment, water quality softener, its main uses include softening and desalination, electronic descaling instrument, filtration and separation, boiler softening, industrial softening equipment, food softening equipment, household tap water softening, etc. Softening equipment is the use ofcation resinThe main purpose of softening the source water is to allow the cation resin to adsorb calcium and magnesium ions in the water, reduce the hardness of the source water, and enable intelligent resin regeneration for recycling.Water that does not contain or contains less soluble calcium and magnesium compounds. Soft water is less likely to produce scum with soap, while hard water is the opposite. Softened water obtained by reducing the salt and magnesium salt content to 1.0-50 milligrams per liter.

2、 Workflow of large-scale industrial softened water equipment:

There are five processes: work (sometimes called water production, the same below), backwashing, salt absorption (regeneration), slow flushing (replacement), and fast flushing. All processes of different softening water equipment are very similar, but there may be some additional processes due to differences in actual processes or control needs. Any softening water equipment based on sodium ion exchange is developed on the basis of these five processes (among which, the fully automatic softening water equipment will increase the saltwater re injection process).

Backwash: After working for a period of time, the equipment will intercept a lot of dirt brought by the raw water on the upper part of the resin. After removing these dirt,ion exchange resinOnly then can it be exposed and the regenerative effect be guaranteed. The backwashing process is when water is washed in from the bottom of the resin and out from the top, which can wash away the dirt intercepted at the top. This process usually takes about 5-15 minutes. Salt absorption (regeneration): The process of injecting salt water into a resin tank. Traditional equipment uses a salt pump to inject salt water, while fully automatic equipment uses a dedicated built-in sprayer to suck in salt water (as long as the inlet water has pressure). In practical work, the regeneration effect of salt water flowing through the resin at a slower speed is better than simply soaking the resin in salt water. Therefore, softening water equipment adopts the method of slow flow of salt water through the resin for regeneration, which generally takes about 30 minutes. The actual time is affected by the amount of salt used. Slow flushing (displacement): After flowing salt water through the resin, the process of slowly flushing all the salt in the resin with raw water at the same flow rate is called slow flushing. Due to the fact that a large number of calcium and magnesium ions on functional groups are still exchanged by sodium ions during this flushing process, according to practical experience, this process is the main process of regeneration, so many people call this process displacement. This process is generally the same as the salt absorption time, which is about 30 minutes. Quick flushing: In order to flush away residual salt, a flow rate similar to actual work should be used to flush the resin with raw water, and the effluent from this process should be soft water that meets the standard. Generally, the fast flushing process takes 5-15 minutes.

4、 Application of large-scale industrial softened water equipment:

It can be widely used for softening the supply water of steam boilers, hot water boilers, exchangers, evaporative condensers, air conditioners, direct fired engines and other systems. It can also be used for the treatment of domestic water in hotels, restaurants, office buildings, apartments, homes, and other industries, as well as for the treatment of softened water in food, beverage, brewing, laundry, printing and dyeing, chemical, pharmaceutical and other industries.
