Water softener according to the application domain can be divided into soft water for domestic and industrial large softened water equipment, it is the main material of food grade ion exchange resins, materials, health and safety, water softening effect is good.

Water softener equipment working process

Work ( sometimes called water, similarly hereinafter ), backwashing, the salt absorption ( regeneration ), slow rinse ( replacement ), fast flushing process of five. Different water softening equipment all processes is very close, just as the actual process of different or control needs, there may be some additional process. Any with sodium ion exchange based on softened water equipment are in the five process on the basis of the development of ( among them, automatic softened water equipment will increase brine refill process ).

Backwash: after a period of working equipment, in the resin upper intercept many raw water brought by dirt, the dirt removal, ion exchange resin can be completely exposed, the regeneration effect can be ensured. Backwashing process is water from the resin bottom wash in, from the top of the outflow, so it can be stopped by the dirt washed away the top. This process usually requires 5-15 minutes.

The salt absorption ( regeneration ) : the saline is injected into the resin tank process, the traditional equipment is using salt pump brine injection, automatic equipment is using special built-in injector injects saline inhalation ( as long as the water with a certain pressure is available ). In the course of practical work, saline at a slower speed through the resin regeneration effect than simply using saline soak resin has good effect, so the water softening equipment are used to slow flowing resin regeneration brine method, this process usually takes 30 minutes, the actual time for salt effect.

In four, soft water equipment selection

1, first you must provide the required the use of softened water system is what kind of:

1) 2 ) 3 ) heating cooling water process water 4) steam boiler 5 ) iron and steel smelting industry 6 ) chemical and pharmaceutical industry

2 time: that is, system water running time / hours water / average / peak / equipment need continuous water supply? If you need to choose the twin set control or double control double bed series, or optional single valve single tank series.

3, water total hardness of water is the municipal tap water \ groundwater \ surface water, total hardness in water using. On certain types of water softener, water hardness, the cycle water must be relatively reduced, resulting in the frequency of regeneration water softener equipment. The relative reduction of the service life of the resin. To avoid this situation, should increase resin volume, which means that the selection of increasing type softener.

In 4, required soft water unit flow (ton / hour ). The user equipment and the nature and;

5, set in cycle water softener type setting, according to the raw water hardness, the resin exchange capacity can determine the theoretical cycle water ( ton).

In five, soft water equipment application:

Can be widely used in steam boiler, hot water boiler, heat exchanger, evaporative condenser, air conditioning, direct-fired machine system supply water softening. Can also be used for guesthouses, hotels, office buildings, Residence, home furnishing, water treatment and food, beverage, wine, washing, printing and dyeing, chemical, pharmaceutical industries such as softening water treatment.
