Hard water in Israel is good for health but bad for property

Hard water is rich in the minerals calcium and magnesium, important for our health; but when these minerals harden and crystallize into hard limescale, they damage pipes, faucets, and heating elements.  Then it is the consumer—private, institutional, agricultural, industrial, and government—that must pay the price.

When limescale is made brittle, it’s no longer a problem

Tamhil’s Salamander manages limescale damage through an electrolytic process.
In this process, a tiny amount of zinc is released into the water.  The zinc’s presence causes the limescale to crystallize as needle-like crystals (aragonite) instead of blocks (calcite).  This change in crystallization property in water is sustained.
    

Pipes and any other area in which contains flowing water – remain clean and free of blockages for many years; only a thin, solid protective layer of limescale remains.
Kettles, boilers, or any other containers of standing water – Only brittle and crumbly pieces (and/or a suspension) of limescale accumulate—easily cleaned by tap water.  Additionally, a thin and solid protective layer of limescale forms within.

• The electrolytic process helps protect your health - because vital minerals are retained in the water, and limescale damage is treated.
• The electrolytic process works independently of
  flow, time or distance, needs no external energy, and is maintenance-free.
• Old limescale in pipes and electrical appliances wears away.
• The electrolytic process is friendly to the environment.
  

Additional technologies for preventing limescale damage:

Magnet
Helps alter the behavior of limescale through local treatment of the appliance to which it is attached.
The magnet is effective for water that is used immediately, because the magnetic activity is not sustained.

Various chemicals such as Siliphus
An addition of unnecessary chemicals to drinking water; these chemicals take the place of calcium and magnesium in the water’s structure.
Maintaining control over appliances is awkward and difficult because the container must be opened to check when the chemicals have been used up, and for cleaning as well.
Maintenance costs are persistently expensive because chemicals and used-up filters must be constantly replaced.

The Venturi principle
The flow of water through a mechanism produces electrical fields caused by the difference in potential between a core alloy and the metal cylinder – a method of preventing limescale damage.
Requires a grounding connection.
Requires complicated yearly maintenance.
Consistent effectiveness of treatment is not assured in respect to time or distance from the appliance.
Necessitates the simultaneous modification of different units, and separate regulation valves for each different supply.
Can lead to corrosion due to the uncontrolled release of various metals into the water.

Softening
Prevents limescale damage by replacing calcium with sodium.
The device is expensive.
Requires a great deal of expensive maintenance of salt.
Not friendly to the environment.
Corrosive due to low pH.
Recommended when there is a specific need for soft water, and not simply as a method of limescale damage prevention.
