High efficient 40m3/hour water softener system/twin tank water softener to remove water hardness

Dual-Tank Water Softener

When a water softener is recharging, it is designed to disconnect from the water system, so it is basically out of commission. For this reason, the regeneration cycle is usually set to occur at night. If softened water is needed during the regeneration cycle, this can be problematic.

If the down time of the water softener is an issue, or if a family is large or lives where water is particularly hard, it may be smart to consider adual-tank water-softening unit with two resin tanks. With a dual-tank unit, when one tank is in use, the other is regenerating. As a result, softened water is being supplied continuously, without any break in service. And because these units operate on demand, they can be sized smaller than single-tank units.

Several models are available. One popular product, the Fleck 9000, has a fully adjustable valve that is controlled by a meter. When the water softener starts backwashing one tank, its control switches the water supply to the other tank, offering a continuous flow rate of 21 gallons per minute.

How does water softener work?(Principles of Ion Exchange to Soften Water )
Calcium and magnesium ions are atoms having a positive electrical charge, as do sodium and potassium ions. Ions of the same charge can be exchanged. In the ion exchange process, a granular substance (usually a resin) that is coated with sodium or potassium ions comes into contact with water containing calcium and magnesium ions. Two positively charged sodium or potassium ions are exchanged (released into the water) for every calcium or magnesium ion that is held by the resin. This “exchange or trade” happens because sodium or potassium are loosely held by the resin. In this way, calcium and magnesium ions responsible for hardness are removed from the water, held by the resin, and replaced by sodium or potassium ions in the water. This process makes water “soft.” Eventually, a point is reached when very few sodium or potassium ions remain on the resin, thus no more calcium or magnesium ions can be removed from the incoming water. The resin at this point is said to be “exhausted” or “spent,” and must be “recharged” or “regenerated.”

The principle of sodium ion exchange and softening treatment is to exchange cation in the raw water with resin, hardness constituents Ca2+and Mg2+ in water exchange Na+ in resin, thus absorb the Ca2+and Mg2+ to make the water to be softened.

2RNa + Ca2+ = R2Ca + 2Na+

2RNa + Mg2+ = R2Mg + 2Na+

After the water treated by sodium ion exchanger, the Ca+ and Mg+ were superseded by Na +.

The Brine Tank
The brine tank is just what its name suggests, a plastic tank that contains a brine, water saturated with salt. The brine solution is typically made with salt or sodium. However problems may result if you are on a restricted low sodium diet in that some of the sodium is transmitted into the drinking water.

Also, the bacteria in septic systems so necessary for the breakdown of waste may be adversely affected by high concentrations of sodium.

The Control Valve and Regeneration
The control valve is the traffic cop in your water softener system. It determines when it is time to clean those plastic beads which are now coated with calcium and magnesium. Older style units use a timer, newer models use a computer controlled meter that determines when it is time based on actual water usage.

To clean the beads the water softener uses a process often called regeneration which consists of three cycles: Backwash, Recharge and Rinse.

Backwash:
Regeneration starts with a backwash cycle where the valve reverses water flow in the tank and flushes the tank of debris. The debris is then eliminated out the drain.

Recharge or Regeneration:
In the Recharge cycle the salty brine solution is pumped into the mineral tank. The highly concentrated salt solution with its positive electrical charge is attracted to the negatively charged plastic beads and forces the magnesium and calcium off the beads.

The salt or potassium by itself is not positively charged enough to displace the magnesium or calcium in normal concentrations, but in the highly concentrated solution of brine, it is strong enough to force the calcium and magnesium off.

The excess magnesium and calcium rich salty water is then flushed out of the tank and down the drain.

Rinse:
The tank is then filled and rinsed with water and the process repeats itself. The beads are now coated with salt. As the calcium and magnesium from the hard water are attracted to the plastic beads, the salt, now in much diluted quantities and smaller electrical charge, is forced off the beads and is suspended in the softened water.

When the beads become nearly all coated with minerals, the control valve starts a new regeneration cycle and cleans them again, flushing the hard water minerals down the drain.
