Weizhi water treatment equipment [Manager Zhao:]
As the name suggests, it is a device that reduces water hardness. It mainly removes calcium and magnesium ions in the water. Water softening equipment cannot reduce the total salt content in the water during the process of softening the water. Since the hardness of water is mainly formed and expressed by calcium and magnesium, cation exchange resin (water softener) is generally used to replace the + and + (the main components that form scale) in the water. As the + and + in the resin increase, The efficiency of resin in removing + and + gradually decreases. After the resin absorbs a certain amount of calcium and magnesium ions, it must be regenerated. The regeneration process is to flush the resin layer with salt water in the salt box to replace the hardness ions on the resin. The regeneration waste liquid is discharged out of the tank, and the resin becomes Soft swap functionality has been restored. Because the hardness of water is mainly formed and expressed by calcium and magnesium. The principle of sodium ion exchange softening treatment is to pass the raw water through sodium-type cation exchange resin to make the hardness components +, + and The + in the resin phase exchanges, thereby adsorbing the + and + in the water, softening the water. If represents the sodium type resin, the exchange process is as follows + + R+ + + + + + That is, after the water passes through the sodium ion exchanger, the + and + in the water are replaced with +. The general operation process of the control valve is: operation, backwashing, salt absorption, slow washing, salt tank replenishment, and forward washing. ) The workflow of softened water equipment includes five processes: (sometimes called water production, the same below), backwashing, salt absorption (regeneration), slow flushing (replacement), and fast flushing. All processes of different softened water equipment are very similar, but due to differences in actual processes or control needs, there may be some additional processes. Any softened water equipment based on sodium ion exchange is developed on the basis of these five processes (among them, fully automatic softened water equipment will add a brine re-injection process). Backwashing: After the equipment has been working for a period of time, a lot of dirt brought by the raw water will be intercepted on the upper part of the resin. Only after these dirt are removed can the ion exchange resin be fully exposed and the regeneration effect can be guaranteed. The backwash process is that water washes in from the bottom of the resin and flows out from the top, so that the dirt intercepted at the top can be washed away. This process generally takes about - minutes. Salt absorption (regeneration): the process of injecting salt water into the resin tank. Traditional equipment uses a salt pump to inject salt water. Fully automatic equipment uses a dedicated built-in ejector to suck in salt water (as long as the incoming water has a certain pressure) . In the actual working process, the regeneration effect of salt water flowing through the resin at a slower speed is better than that of simply soaking the resin with salt water. Therefore, softened water equipment is regenerated by the slow speed of salt water flowing through the resin. This process generally takes 3 Minutes or so, the actual time is affected by the amount of salt used. Slow flushing (replacement): After using brine to flow through the resin, the process of slowly flushing out all the salts in the resin with raw water at the same flow rate is called slow flushing, because there are still a large number of functional groups on the resin during this flushing process. Calcium and magnesium ions are exchanged with sodium ions. According to actual experience, this process is the main process of regeneration, so many people call this process replacement. This process generally takes the same time as inhaling salt, that is, about 3 minutes. Quick rinse: In order to completely rinse away the remaining salt, the resin should be rinsed with raw water at a flow rate close to the actual work. The final water output of this process should be soft water that meets the standard. Generally, the quick flushing process takes - minutes.

Fully automatic water softener control method
Single tank time type: Microcomputer time control is adopted, and the equipment automatically enters the regeneration state after running to the set time , can be regenerated once a day or multiple days.
Single tank flow type: It adopts turbine flow control or electronic flow sensor control. When the water production volume of the equipment reaches the preset flow rate, it automatically enters the regeneration state and can be regenerated multiple times a day.
Double-tank flow type: It can be divided into one-use and one-standby type and simultaneous operation and separate regeneration type.
One-use and one-standby type: One tank is running and the other is in standby. When the water from the tank that is running first reaches the set flow rate, it enters the regeneration stage. At the same time, the other tank enters the working state. In this way, the two tanks work alternately for regeneration, which can last for hours. Continuous water supply.
Simultaneous operation and separate regeneration type: Two tanks run at the same time. After reaching the flow rate, one regenerates first and the other continues to discharge water. The first regenerated tank enters the working state after the regeneration is completed, and the other tank enters the regenerated state. After both tanks are regenerated, Entered into simultaneous working state again.
