Zeolite for Water Treatment

Published on by in Academic

I have used natural zeolite of the phillipsite family of Na homoiconic form as a model to treat water from dissolved heavy metals like iron and cadmium.

The particle size was 0.6-1.4 mm.

It has been found that the efficiency of the treatment is affected by hardness.

I want to know if any body or a water facility is using any type of zeolite to treat water at the municipal level and how they manage the interfering ions.

    Are you using zeolite in as a media bed filter or as a pre-coat filter machine, or as a continuously applied filter aid?  if it is a pre-coat filter is it a once only use or recycled media bump type filter operation.

    We have plenty of experience in these applications.  We could write a lengthy dissertation.  The efficiency of removal for precipitates such as iron and cadmium will vary with the type of filter process being applied.

    In addition, the chemistry parameters of the feed water plus its temperature will have more than just a significant impact on the filtration quality.

    Also, natural or synthetic zeolite material?  

    Hardness yes it will always cause variation with a zeolite media, again a materials consultant would need to know the actual respective calcium, magnesium and Iron hardness and other water parameters that affect scaling of these before being able to assist your dilemma.

     

  3. Hello Mohammed,

    We work with a mineral liquid, that contains 70-102 ionic minerals which comes from Biotite rock. Adding it to any water will remove/reduce:

     Heavy metals, Petrochemicals, Agrochemicals, Pharmaceuticals, Bacteria, Viruses, Parasites, and more.

    All while mineralizing, ionizing, and structuring the water, and keeping those effects after only one treatment.

  4. Seems a shame letting all of those nutrients being extracted from the water and leaving the water unfit to drink yet government approved.  You may want to look into bioremediation. The microbial species is Archaea. It chelates all heavy metals into their elemental/nutrient state. You eliminate any need for chlorine and after 40 years of testing Zero pathogens found. New technology is actually 1 /10th the cost of the old outdated systems. This allows 100% recycling of water. Very important in arid climates etc.  

  5. Hi, Calcium and Magnesium both cause hardness, and because they are also cations they can cation exchange onto and off the exchange sites on natural zeolite. We've been using natural zeolites to take sodium out of solution and put calcium and magnesium back into solution; so the opposite of your problem. Natural zeolites have different cation selectivity preferences, you can find ones that have a very low affinity for calcium and magnesium. How are you regenerating your natural zeolite? How are you filters arranged? There are solutions to your problem.

  6. We use no sorbent for waste water treatment from heavy metals. The Electromagnetic Vortex Layer devices show the high efficiency in heavy metals removing processes. Here is the description https://youtu.be/sFRbTvX6c6o
    Here you can see the figures

    Acid and heavy metal content before processing:
    pH: 1.75
    Fe /iron/: 9.7 mg/liter
    Cu /copper/: 19.29 mg/liter
    Ni /nickel/: 5.8 mg/liter
    Cr+6 /hexavalent chromium/: 19.08 mg/liter

    after processing on Vortex Machine the figures are as follows:
    pH: 6.74
    Fe /iron/: 2.77 mg/liter
    Cu /copper/: 0.68 mg/liter
    Ni /nickel/: less than 0.02 mg/liter
    Cr+6 /hexavalent chromium/: less than 0.005 mg/liter
