That circuit is based at a technique to remove or neutralize the salt in water, and protect the pipes at home as well as the washing machines or our selves from salt. Its called water softener and its automated circuit using two 555 timers.

The cost of parts is nearly 10$ and its very easy to build it.

Looks like all the resistors are present to me. First timer ~ 4.6Hz, second timer ~1.5Khz. The first timer is frequency modulating the second timer. "L" is an inductor, a coil of wire would around the pipe to couple the water to a varying magnetic field. Can't imagine how this softens water.

Bogus schematic. left side is missing, where timing resistor would be, on the first IC!!! Also, on what kind of chemical or physical mechanisms does it work ???? To make any difference, on the water passing thrum that pipe, you might need a few kilowatts!!! Both oscillators seem to output same frequency ?!?!? Jeez...

sir/madam, This is sethu from india.i am a regular reader of next.gr.now i want to know some details about water softener circuit.in the given circuit what is "L" it means what?? plz explain that and give some details about what kind of chemical reaction will take place in water due to this circuit..thank you.

M any more thanks for issue of water softener circuits. O.k. Since impure water contains solute particles as calcium&magnesium in the form chlorides and sulphates the hardness come out.Even though there will be different system such as r.o&ion exhange process, water softening by high frequency mean

Complete idea regarding high frequency based water softening system details available on my mail . My mail id shahul_1965@rediffmail.com .

I bought a commercial version. This circuit keeps minerals in solution. Before, I had rock hard crusts on faucets and showerhead, after 6-12 months (works slow!) they are now soft, easy to remove, and don't form as fast. I also built this circuit, those 10nF caps should be 10 microfarad!

please understad electro refining during crystalisation of impure silicon to pure silicon crystals by recrystalisation methods from solution contains silicon.

What is the value of the coil. Thank You Lou
