Softening Water Treatment Equipment Selection Plan

Standardized operation process of softening water treatment equipment includes five processes: operation (sometimes called water production, the same below), back washing, salt absorption (regeneration), slow scouring (replacement), fast scouring.

All processes of different softening water equipment are very close, but there may be some additional processes due to the different practical technology of deionized water treatment equipment or the need for operation. Any softening water equipment based on sodium ion exchange is carried out on the basis of these five processes (in which the fully active softening water equipment will add saltwater reinjection process).

Backwashing: After a period of operation, the equipment will block a lot of dirt from the raw water of the coating water treatment equipment on the top of the resin. After removing these dirt, the ion exchange resin can be thoroughly exposed, and the regeneration effect can be ensured. The backwashing process is that water is washed in from the bottom of the resin and out from the top, which can wash away the dirt blocked by the top of the water equipment for cleaning the glass tank membrane. This process usually takes five to fifteen minutes.

Salt absorption (regeneration): In the process of brine writing into resin tank, the traditional equipment is to use salt pump to write brine, and the fully active equipment is to use special built-in ejector to inhale brine (only with a certain pressure of water intake). In the process of practical operation, the regeneration effect of brine flowing through the resin at a slower speed is better than that of the resin soaked in brine alone. Therefore, the softening water equipment is regenerated by the method of brine flowing through the resin at a slower speed. This process usually takes 30 minutes, and the practice is always affected by the amount of salt used.

Slow scouring (replacement): In the future, when salt water is used to flow through the resin, the process of gradually scouring all salts in the resin at the same flow rate is called slow scouring. Because there are still a large number of calcium and magnesium ions on the functional groups exchanged by sodium ions in this scouring process, according to practical experience, this process is the primary process of regeneration. Process, so many people call this process displacement. This process is usually the same as the time when salt is absorbed, i.e. 30 minutes at the mercy of the process.

Rapid scouring: In order to thoroughly wash out the residual salt, the flow rate close to the actual operation should be selected and the resin should be scoured with raw water. The final effluent of this process should be qualified soft water. Usually, the fast scouring process is 5-15 minutes.

[Peacetime use of softening water equipment]

Bath, water is the most basic, and the hardness of water, let us enjoy the button. After taking a bath, we will find that the skin is tight and itchy. If we grasp it with our hands, it will leave a white mark. Why? Because when hard water touches the skin, it leaves an invisible film of water and alkali, blockages the pores and becomes a hotbed of reproductive impurities - causing cracks, itching and dullness, or causing redness and allergy. Especially the skin of infants is more tender and sensitive. Often itching is caused by alkali and water, so after bathing, children will cry. Parents often mistake children for fear of water.

Instead, bathe in soft water without water and alkali. Without water and alkali film, pore can be thoroughly cleaned and breathed freely. It is as white and smooth as moisturizing lotion. When infants are bathed in soft water, instead of crying, they refuse to leave the bathtub.

When shampooing, without the effect of heavy metals in water and alkali, the dyed hair is no longer simply discolored and discolored. Because there is no residual water and alkali in the hair, it will become clean, smooth and easy to finish.

With soft water bath, the skin is shiny, no itching, the skin is soft and lubricated, the hair is not fettered after washing, and the hair is graceful, natural, free, loose and rare luster; the clothes washed are absolutely free of static electricity, soft and bright as new, and save at least 50% of the amount of detergent; protect the beauty of high-grade sanitary ware, water heater, loosening, and so on. Flower sprinkler is no longer blocked, bathtub, faucet and other metal surface common spots lost traces...

[Selection of fully active water softening equipment:]

1 Heating 2 Cooling and Supplementary Water 3 Technology Water 4 Steam Boiler 5 Steel Exercise Occupation 6 Chemical Pharmaceutical Occupation/7 Heat Exchange Station?

2. Water consumption time of sodium ion exchanger system: running time/hour water consumption/average value/peak value?

Is the selection of fully active softening water equipment in need of continuous water supply? If the demand is selected, double-bed centralized control or double-bed control series, or single valve and single tank series can be selected.

4. The unit flow of soft water required (ton/hour). This depends on the nature and requirements of the user equipment, so we can choose a standard and reasonable type of water softener.

5. The Setting of Periodic Water Production Volume

After setting the type of fully active softening water equipment, according to the hardness of raw water, the capacity of resin used in AC operation can determine the theoretical cycle water production capacity (tons).

[Guidelines for Selection of Fully Active Softener]

1. Fully active water softening equipment type selection controller: completely select the American FLECK Fulake, AUTOTROL Atuzu active control valve. AQUAMATIC YAKE Jacques

2. Resin tank: Can be selected in many ways: domestic RFP tank, stainless steel tank, metal lined plastic tank (PE liner)

3. Selection and operation of fully active softening water equipment.

Sm-flow type: active recovery when the prepared water reaches the set value, which can be applied to all soft water preparation of water supply system.

S-time type: It is suitable for water supply system with stable water volume, and the shortest recovery and regeneration period is 24 hours.

4. Selectable equipment combinations:

(1) Single-bed control: suspend water supply for 2 hours or continue to supply raw water (hard water bypass) during recovery period.

(2) - Single-controlled twin beds: Replace water supply, one-size-fits-all.

(3) - Double-controlled twin beds: Replace water supply and use one spare type.

(4) Double-controlled twin beds: water supply together, replacing the regenerative type.

(5) Multi-control multi-bed: more than three resin tanks are used in parallel, suitable for large-scale water supply system.
