The fully automatic softened water system consists of a multi way valve controller, resin tank, strong acid cation exchange resin, water distributor, salt valve, salt tank, etc.
one ️⃣、 Classification
Fully automatic softened water is divided into time control type and flow control type according to the control valve model.
- Time controlled type: It sets the regeneration cycle based on hourly production and cycle water production, and is generally suitable for situations where water consumption is relatively stable.
- Flow control type: It starts the regeneration program based on the periodic water production. When the equipment is running, a dedicated flow meter counts the total water production. When the total water production reaches the set periodic water production, the controller starts the regeneration program for automatic regeneration. The regeneration of the equipment is independent of the running time and is generally suitable for unstable water consumption, continuous water use, etc.
two ️⃣、 working principle
This product uses strong acidic styrene based sodium resin (NaR) to replace the hardness components Ca2+and Mg2+in the raw water, softening the raw water. The reaction is: 2NaR+Ca2+(Mg2+)=R2Ca (Mg)+2Na+. After the resin adsorbs a certain amount of Ca2+and Mg2+, regeneration must be carried out. Regeneration is the process of rinsing the resin layer with saltwater from a salt tank. The Na+in saltwater replaces the hardness ions on the resin with water, and is discharged from the tank with the regeneration solution to restore the resin exchange capacity and continue softening the water production. The reaction equation is: R2Ca (Mg)+2Na+=2NaR+Ca2+(Mg2+). The regeneration process includes: backwashing (loosening the resin layer) - salt absorption slow washing (replacement process) - forward washing (washing away calcium and magnesium ions) - water injection (preparing for the next regeneration).
three ️⃣、 Features of the equipment
- The degree of automation is high, and the water softener automatically completes the cycle process of softening and regeneration according to the pre-set program. Daily operation does not require manual operation except for adding salt.
- Small footprint, compact device structure, small and lightweight.
- Strong corrosion resistance, the tank body is made of fiberglass and engineering plastics, which can avoid the corrosion of equipment by regenerants.
- Reliable performance and stable effluent quality.
- Flexible selection, can choose single tank, double tank, or multi tank systems according to needs; Time and flow control methods; Simultaneous regeneration, alternating regeneration and other operating modes.
four ️⃣、 Scope of application
- Various industrial and civilian softened water equipment such as boilers (steam, hot water), heat exchangers, central air conditioning (to prevent scaling)
- Circulating cooling water system (preventing scaling of cooling towers)
- Washing and bathing water (saving detergent and increasing cleanliness)
- Food, beverage, brewing, medicine, textile, printing and dyeing, papermaking, etc. (improving water quality)
five ️⃣、 Precautions for installation of water softener:
- No installation foundation is required, it can be installed horizontally on the foundation;
- Require that there is a sewage outlet on the ground near the equipment;
- If the inlet water pressure is lower than the required value, a water supply booster pump must be installed;
- The softened water outlet pipeline is a direct heating device and must be equipped with a check valve to prevent hot water from flowing back and damaging the resin.
- Keep the salt solution at saturation concentration, and the solid salt solution should be higher than the liquid level.
After installation, the pipeline should be flushed to prevent impurities from blocking and contaminating the resin. - The user shall provide information on the water pressure, quantity, quality, and usage conditions of the raw water, so that our company can recommend the appropriate model of water softener. Specially designed according to site conditions. Provide installation and debugging guidance as well as operation training
six ️⃣、 Other instructions
- When regenerating a single tank system, stop producing water for 2 hours.
- When the equipment is not in use for a long time, soak the resin in 5% salt water to prevent mold growth.
