MMM (Multifrequency, Modulated, and Multi-wave) Ultrasonic Technology

Rick1234

Hello Element14 community!

My quest is to build an MMM ultrasonic water treatment system for use in the motel and laundromat industries.  

Basically, to ultrasonically negate the scaling ability of the minerals in the water before they can form on the inside of the pipes and heat exchangers walls.

The MMM paradigm greatly eases the normally strict mechanical ultrasonic interface to the target load ..... as the MMM generator constantly frequency "sweeps" and "optimizes" its effects on the scaling minerals in the water.    

My early thoughts:

PC control to set parameters (power, frequency sweep, modulation, etc)  +  Adaptive Digital Signal Processor (ADSP)  + Ultrasonic Power Driver  

Minimum ultrasonic "contact" time with the scaling minerals (calcium & magnesium)  during a max. 50 gpm water flow rate = 1.5 seconds

Ultrasonic transducer and horn to be of a "clamp-on" type design (ie: surrounding the water feed pipe)

The main attribute of MMM is its ability to "self-adapt" to any varying physical sonic envelope and load ..... on-the fly! (w/feedback loop sensor) 

Its my contention, that in this application, the sonic envelope (pipe) and load (water) is "fixed" and should afford a simpler software implementation script. 

Where to start?  (Note: i'm day one working with ultrasonics!)    

Can anyone recommend a preassembled factory evaluation ADSP board suitable for this application and an ultrasonic power driver board?  

Thank-you!

  • I am extremely dubious that ultrasonic excitation of water in   pipe will have any effect at all on scaling downstream of the excitation area.

    Do you have any research data that suggests this actually works. I did some web searching and found lots of scammy looking companies selling ultrasonic scale preventers but I couldn't find a single reputable looking explanation of how it might work, let alone any data.

    This is a typical example:

    https://www.ultrasonicdescaling.com/technologies/the-physics-of-industrial-anti-scaling/

    See the amazing pulsing diagram near the start and look at the adjacent scale - red  = 10E6 microns = 1m.

    So it's garbage  -  1m displacement in water at 20kHz would need GW.

    The diagrams that you show are not convincing.

    You need to do some serious research and find some hard evidence that this idea will work before putting any effort into building one.

    And since it looks to me as if you'll be competing with some world class scammers as well as plenty of reputable companies making water softeners you'll need a lot more than just an idea to make a business.

    Good luck.
