Multi-way valve automatic water softener
Why is hard water a problem?
As we already mentioned above, hard water is water that has excessively high
levels of calcium and magnesium. In our area, it can be a major problem,
although it is an issue in most areas of the country. As hard water passes
through your supply piping, water heater, and any other aspects of your
plumbing system, it tends to leave behind very small mineral deposits. This
is commonly seen as a yellowish or greenish discoloration on faucets or drains.
Over time, this can harden into a scale covering on the interior surface of your
pipes, thus reducing the aperture through which water flows throughout the home.
It can also create serious problems for your water heater.
What is hard water?
Calcium and magnesium leach back out of the water wherever it constantly flows,
so you’ll see a yellow-white crust forming on faucets, around pipe joins and inside
of your coffeemaker and dishwasher. You can use white vinegar periodically to clean
these appliances, but the buildup will come back.
Minerals in water also tend to bond with the molecules in soap, producing a
scum-like substance sometimes called “soap curd” that builds up on shower
curtains and leaves a film on glassware in the dishwasher. This chemical
bonding also reduces the amount of soap molecules available to form a lather
–which means you have to use more soap to get the job done.
The Ion Exchange Process
The Ion Exchange Process Water Softeners remove hardness from water by a process known as ion exchange. The media, called resin; in the softener is charged with sodium (or potassium) ions. When the hardness ions come in contact with the resin beads the hardness ions are collected and the sodium (or potassium) ions are released, thus the term ion exchange. The hardness ions are exchanged for sodium (or potassium) ions. The typical cations found in the raw water are exchanged within the resin bed for sodium or potassium, as shown in the illustration. Normally, when two-thirds of the resin bed is exhausted, the softener will allow hardness to slip through. When this occurs, it is time to regenerate or recharge the resin bed using a salt and water mixture, known as brine. Sodium chloride (NaCl) or potassium chloride (KCl) are normally used for this purpose. Regenerating the resin bed refreshes its ability to exchange ions.
Application
Mainly used in industry and civil water softening preparation, such as Boiler feed water make-up water, air conditioning system make up water, heat exchanger, power plant, chemical, textile, printing and dyeing, bio-pharmaceutical, Electronic system and water pretreatment.
System automatic water softener widely used in steam bioler,heating bioler,exchanger,air conditioner, and other systems water softener,also used in hotel,restruant,office, and other life water treatment and food,drinking,wine,washing,textile,chemical,medicine and other industrial softener water treatment.
