Softened water is essential for many industrial and commercial uses. Boiler feed water, circulating water, heating and air conditioning make-up water, and other forms of production water can be effectively treated with this process. On average, anywhere from tens of tons to thousands of tons can be prepared by our automatic water softener.

Water hardness commonly consists of calcium (Ca2 ) and magnesium (Mg2 ) ions. Passing through the resin layer of the water softener, these hardness ions are exchanged, adsorbed and their concentration decreases. Simultaneously, sodium (Na ) ions are discharged into the water in equal measure. Ultimately, softened water devoid of hardness ions is produced.

When the resin has taken in a certain amount of calcium (Ca2 ) and magnesium (Mg2 ) ions, the regeneration process is activated to restore its softening and exchange capacity. This is done by washing the resin layer with salt water in a salt tank, and then releasing the hardness ions and regeneration waste liquid outside of the tank. This allows the resin to regain its original properties.

The multi-valve automatic water softener system is designed to allow for the smooth functioning of various processes associated with water softening services, utilizing different control diaphragms (e.g. hydraulic and pneumatic). Each valve is connected to the controller which follows a predetermined program to open and close the necessary passageways, allowing for easy running and regeneration. The system also contains resin and salt tanks, essential for completing the process.

• Valves to power the operation need to be diaphragm valves of the hydraulic or pneumatic variety, which have wide international usage. These valves are made of reinforced plastic, providing longevity as well as advantageous corrosion resistance. Their service life is epochal; the valve body can endure up to 30 years, and even the diaphragm endures more than 8 years. The valves are suitable for tanks sized between Ø 600 and Ø 3000.
• The valves can be effortlessly set up and preserved, making it simple for both professionals and nonprofessionals to carry out necessary inspections, maintenance, replacements, as well as other operations.
• The JMA multi-valve softener allows for customization of the time for each process, making operation easy and convenient.
• In the event of a power outage, each of the program steps can be fulfilled by manually rotating the distributor. The process is easy to complete.
• Regeneration operation can be tailored to individual needs, with the option of either upstream or downstream selection.

• The selection of equipment is not limited to the above specifications. The multi-valve automatic soft water tank can be combined with larger tanks (such as five tanks). We can make special design according to the raw water analysis data and water requirements provided by customers.
• Equipment selection shall be determined as follows:
  (1) counter-current regeneration or co-current regeneration;
  (2) Flow control or set-timer.
