Frequency Resonance and EMF Differences.

Hello fellow Aussie and welcome to the forum.

From your post, it seems that you are trying to determine and select a thesis project for your final year. Is that correct?

I suspect that you have made a quantum jump when writing your question. You mention "frequency resonance" and "EMF" that are terms that I understand in an electrical context rather than a water treatment context. Maybe you have seen some information where these characteristics are applied in a very particular way to achieve an outcome in water treatment.

Can you cite the source of your understanding (like is it some manufacturer's claim of their equipment operation) so that we might be able to help you further?

Hi there, Apologies for the gap in responding and some clarification.

A quick update on me first so you know my capabilities. 17 years in Water treatment, mainly desalination. Design, manufacture and commission. Hands on "not behind a desk all the time" Consult to the national industry now.

EMF, involves as it says much like a sacraficial "zinc" anode in a bore casing to remove iron, calcium scale deposits.

Frequency resonance, involves an electrical field (EF) modulated in the low to very low frequency range. I need to see some science to prove or disprove the below.

1/Water molecules surround and dissolve mineral ions e.g + = Na+ / - = Cl-

2/ the water molecule is Dipole i.e oxygen = negative / hydrogen = positive.

Charges on water are attrcted to mineral ion charge so Hydration / dissolving occurs.

Whilst active FR is occurring,

3/ Additional water molecules surround mineral ions.

4/ Water molecules come between mineral ions accellerating them.

5/ Water nolecules fully dissolve the mineral whilst sharing some water molecules.

Finally, Each mineral ion is independant of others and is now a free agent.

It may be taken that each freed ion can scavenge unfreed ions from a mineralcompound or mineral layer, in turn freeing them.

I am undertaking trials of the above nature to verify if "FR" indeed does work in TDS lowering and scale prevention.

Looking for the science to prove it works.

Cheers

There are 2 companies that I am looking into, there may be numerous ones that provide the same type of product all over the world.

Hydrosmart, Calclear.

I will be organising, bilding and conducting 2 pilot trials to verify performance in an Salt Water Reverse Osmosis plant process application.

Hope to hear back from some for discussion.

Cheers

George

THIS will be more useful.

I would suggest that you start searching for information on ultrasonic cleaners, since this is the established technology that matches your intended application.

But the OP wants to use this technology for water purification.

Ultrasound should be usable to descale the equipment, afaik, for example in an evaporative desalination process. I don't know of any other application for RF in water purification processes.

The OP is trying to precipitate scale upstream of RO. For RF in water demineralization, see http://www.freepatentsonline.com/8025801.pdf

... the "inductor"? Not exactly RF, afaict,... but an interesting concept, using repulsion of the ions in the brine - wonder if it works.

Hi all,

Thanks for your efforts to assist, I have researched quite a bit anf found that there is a bit of "smoke and mirrors" philosophy to this method of scale prevention. Which is likened to the sacraficial sections placed on bore casings to attract and reduce iron scale and zinc anodes on marine motors etc.

I believe the interpretation of the magnetic frequency applied to saline water does dissasociate molecules and turn them into free agents therefore keeping them soluable to allow easier passage through the TFC RO membrane. The frequency musy vary for varying cationic-anionic water chemistry so there is some scepticism. This may be beneficial in large scale desalination plants in the reduction of polymers and antiscalants dosing and promoting membrane longevity.

Energy consumption wise, it is cheap to run. Maintenance, almost nil.

The only drawback is that high EMF's are a health issue if exposed to them frequently.

Much like breathing Sydney air.

The trials are underway and without IP infringement, I will post my thoughts.
