PIC12F1822 WATER SOFTENER

This softener generates a sweeping frequency from 2 to 20 KHz. It may give better results in some hard water. The 220uH coil drives the coil on the pipe with a current of about 0.5A, this allows high efficiency with less heat and less cost of running.
Power supply has to be regulated 5V that can source 200mA.
The 8 pins PDIP buffers is a mosfet driver. IC's that can be used are: TC4420, MCP1406, MAX4420. These are very similar and pins are identical.

ARDUINO WATER SOFTENER

This softener generates a sweeping frequency from 400Hz to 5 KHz. It may give better results in some hard water. The output of the Arduino is 64KHz Pulse Width Modulated to the sweep of 400Hz to 5 KHz, the 220uH coil blocks the high frequency and drives the coil on the pipe with a current of about 1A, this allows high efficiency with less heat and less cost of running.
Power supply to the Arduino is 7V to 10V , 100mA or more.
220uH coil limites the current through the coil on pipe to about 1A.

ELECTRONIC HARD WATER SOFTENER

The electronic water descaler is more effective device than powerful magnets placed around the incoming mains water pipe. This device operates by wrapping coil of wire around the incoming water mains to pass a magnetic field through the water. The theory is that it causes the calcium in the water to stay in solution and so inhibit it from adhering to pipes, taps, baths and kettles.
Reading many sources about the way it works I decided to try and make one. A few days after installing it I noticed a difference in the behaviour of the deposit of lime scale in the kettle and around the sink, it was much easier to remove the deposit, also the scale deposit was reduced to about half the amount.
Since it's unknown the true benefits of lime to our health and we also don't know the effect of the residual magnetic in the lime, it is recommended to use the descaler for washing water only.

There are 2 version for the circuit, both have similar characteristics. Select the one that will be easier for you to get the components.

CIRCUIT DIAGRAM 1 USING 555 TIMER

Circuit 1 Description
See also Technical Tips

  • The +V is 8 to 10VDC. The current at 10V is 50mA. Any 9V universal power supply is powerful enough. Make sure the voltage does not exceeds 15V because it can damage the 555 timer IC.
  • The coil on the water pipe is made of 5 meter long insulated wire of 24 to 20 gage. The wire is turned around the copper or plastic water pipe (it can not be steel pipe) in a single layer. On a pipe of 20mm diameter it will form 55 turns. Since the wire is 5 meter long the number of turns will be different for different pipe diameter.
  • The circuit is a 12KHz oscillator with a coil of 470uH at the output to limit the current through the water pipe coil to 300mA peak.
  • 56K resistor and 1nF (1000pF) capacitor determent the frequency.
  • You can use equivalents for BC337 and BC327.
  • 555 timer has to be bipolar (555N) .
  • 470uH can be any type that can carry 300mA.
  • 1N4148, 680 ohm and LED are optional components to indicate output signal and coil are present.
  • All resistors are 1/4 watt, 5% .

Comment: Hi Moty, sorry about the unconvenience. Maybe it's better to shift the topic to pnd0080@gmail.com , thanks ? For now I have uploaded the code again, from the Arduino Project site. The Voltage Values seemed to be the same, Pin 7 of the Chip fastly changing sometimes to 1-3 Volt. The Chip is a "TC4424EPA" so on the package. On the Chip it's printed, ["TC4424EPA" - (2 unrecognizable symbols) - 7UK - 2148 ] .

Comment: Hi Moty, Thank you for the answer. I checked the wires twice on a breadboard. Seems so far correct. The Voltage on Pin 11 seems to jump between 60-200mV. And on Pin 7 of the Chip, also around between 20-200mV. The Power Supply is 9 Volt / 1 Ampere . Do you know if Test Strips for Water Hardness could be helpful to see the difference in the Water ?

Comment: Hi Liam, When the softener runs the 10R resistor and the 4427 get warm, it's one way to tell that it works. The DC voltage at pin 11 of the Uno is about 2.5V , if 0 or 5V then the Uno has a problem. The voltage at pin 7 of the 4427 has to be about half the power supply voltage. The LED has to be red or green, white or blue LED aren't suitable.

Comment: Hi Mr. Moty, I have a question about checking the Circuit with a Volt Meter. In my case I used Arduino Uno with enough Input Voltage. And the circuit from https://projecthub.arduino.cc/moty/water-softener-6e096a However the Led doesn't light up. How and where should I measure the Voltage to see if it works. Or which Values and where should I expect ? Kind Regards, Liam

I am sure you're busy and people ask a lot of stuff, but do you happen to have a version of this code that does not use registers and the weirdness of OCR2A etc? I am sort of sure the same thign can be done with just C and functions available for PWM. Thanks for any consideration. (The circuit qas fun to build and now to see about any differences in calcium and lime. AND have you ever tried longer coils? Multiple coils? Thanks!

Comment: Hello Moty, You are right, of course, I did not see this error. I didn't pay attention to the oscillator-end of the circuit. However, I was under the same impression as you, but then I came across an interesting article you might want to read, if you have the time and head space: https://www.cwt-international.com/cwt/images/stories/Products/Vulcan/Studies/EN_Water_Treatment_Dr_Juhnke.pdf I think, I am going to try an "assemblage" of what I learned from your Arduino project and my own (influenced) creation.

Comment: The ckt & explanation have been very useful. I tried higher current for better effectiveness ie., 1 to 1.5A peak, hence used TIP122 & TIP127. Some modification I attempted. 1)4.7uF, Poly AC Cap to avoid heating. 2)For varying the frequency from 5khz to 10khz continuously,as some mfr. claim, a LM324 triangular wave generator preceding the 555 stage. 3)Thin insulation PTFE tape wound 20gage cable. 4) used 3 coils in series, one on incoming city water to sump, one on sump to OH tank, one on solar water heater incoming. 5) 12V , 2A DC adaptor supply (INR 150/=). Did not use 470uH, since not available. Now, in another house, with 1.25 inch pipes,I am planning to use 2 to 2.5A peak, by paralleling two TIP122 & two TIP127. I noticed that the ckt & theory of descale works.

The reputable companies don't make electronic softeners because their scientists discovered the same things you have discovered. There are many articles about this subject on the net.

Comment: I checked TDS, Ph and gravity dose not change. After water passes from 12 to 15 KHz field oscillator no parameters found changed. Can you explain it?

Comment: Hi Suek. In most browsers you right click the image and select to save it. I attached a copy. The softener gives different results depending on the minerals in the hard water.

Comment: I'm really interested in this as a project. Let me start by saying though that I cannot get the images of the circuit diagram to load properly is there anywhere else i can go to see them. Does this softener reduce the hardness of the water?

Comment: Hi Girish. The number of turns isn't critical. The current through the coil is dictated by the inductor on the PCB. The copper tube reduces the magnetic flux because the circuit sees it as a single turn coil. You will get stronger magnetic flux winding the coil on a plastic tube. There are many reports of researches of softeners on the web. You will find that the results of experiments are inconclusive and vary a lot depending on the minerals in the water. This leaves you with the option that you have already seen, to wait and see the results in your house. I've never tested the kit from Thailand, looking at it made me convinced that it is exactly my circuit. The LED is on the output so if its lit it means that the output is on.

Comment: Hi Moty Thanks for the instructions for novice DIY enthusiast explaining the science. I have ordered the kit from the supplier, however with a 22mm pipe I achieved more that 60 turns, will this affect the performance of the device. On the kit there is a LED to indicate power supply on, is there any thing else that needs to be noticed for the device to be working. Some of the comments are about frequency counter and oscillations, am I reading too much into it. Should I just wait and see if there is improvement in the water condition and scale formation. Thanks.

Comment: Hi Gulabhai. Use the coil as shown on the project page. You may not get much effect of softening with 50 mm tube.

Comment: Hi Tim. Thank you for noting that out. The eBay seller copied the description from my website, I also had a close look at the PCB, so it’s very likely that they used my circuit. Of course everything on the site is totally free to use. I’m also pleased to fine that some more people will be able to DIY soften their water. I will add a link to this kit.
