Nickel Removal from Drinking Water

Published on by in Technology

We have a potable water plant with slightly elevated nickel concentration levels.

Does anyone have experience with nickel removal?

Which technology and chemicals should be used?

    Dear We are working in such an area where the TDS Value ranges from 2000-3000 and arsenic is too present in the water.. The 95% people live below poverty line... DO you have some affordable and sustainable solution to resolve this..

    1. Yes, my company has successfully removed arsenic to WHO drinking water quality for 2,000,000 people in developing countries across Asia using an innovative filter media and simple, automated filtration system.

      Please email me at andrew@waterandoilsolutions.com.au if you would like to know more.

  3. My doctorate was in the area of heavy metal removal of water. The most suitable process for low levels of nickel, which I recommend is adsorption. You can use resins of CATIOnS, or CLAYS that are more economical. One clay you can use is activated vermiculite. Kind regards.

    2. I am interested in possibility to improove coagulation's. Perhaps activatedvermiculite are more economical. Give me, please, more details . Thank you, Miroslav

  4. Miroslav... One of my M.Sc. students have just concluded a study on the removal of Ni from water using simple natural materials. I do not like to compete with some of the responses from water treatment companies. But definitely, as a researcher, I would be pleased to get the first application of our findings outside Iraq. We will suggest  a material from your surroundings, no purchase of any chemicals, and there will be no need for filtration to remove the removed Ni. We will ask for your support for the research work It will not exceed 10% of what water treatment companies may ask as a cost of the removal. The solution can be sent for you by email the soonest.   my email: brbt2m@gmail.com     Regards  

  5. Dear Miroslav,

    We are a France based water treatment company providing solutions for the bottling industries (visit http://www.ice-water-treatment.com/en/) over the world. We have dealt with Nickel issues in water aimed at beeing bottled as mineral water, and could propose some specific processes according to you water characteristics. Feel free to transmit me your data, which I would forward to the sales engineer in charge with your geographic area.
    I hope that we talk soon.

  6. Dear sir,

    we require more information like: quantity of water to be treated. total dissolved solids of the water, pH of the water. We can give you chemical precipitation method with treatment scheme include Lamella settler, MGF, ACF, resin filtration+ RO. the treatment scheme depend on concentration of nickel and other heavy metal in water.

    please share analysis report of the concern water, so we can give you detail techno-commercial offer.

    Thanks

  7. I suggest you carry out a purification by displacement. Using a piece of magnesium, you will have the following reaction:

    Ni2+ Mg  ® Mg2+ + Ni which precipitates.

    In addition to Nickel you will be able to rid the water by the same process of the other harmful heavy ions like lead, mercury and others.

  9. Is source of Nickel known and can it be curtailed?

    I can suggest Lab testing for samples : Try very mild dosage of Sulphuric acid to get Nickel precipitated to a sulphate salt and after filtering the coagulated nickel salt, add Sodium bi-carbonate to correct the Ph.  

    Also try in lab whether Ni can react with Bromine to give a filterable Nickel bromide ) and it can be by adding a very small quantity of Sodium or Calcium Bromide or even bubbling small quantity of bromine thru a closed circuit .Only Lab experiment suggested on trial basis for an inexpensive solution.

  10. These gentlemen are all correctIon Ion exchange, RO, GAC Adsorption(limited life), and coagulation then filtering.

    1. We done many experiments. RO is too expencive, GAC fail in removal, ion exch do the job (but not as expect), coafulation are our goal bit water are  so cold , thus coagulation working at very limited level.

      FYI: Capacity: 130 Lit/sec - permeate.

  12. See  WHO Guidelines for Drinking Water Quality 4th edition, p 397. Conventional coagulation works. Cation exchange  also if necessary.

    1. Ion exchange work, as told before, but not as we expect. Coagulation just remove from 48 ppb to 27 ppb. That's all from conventional coagulation !!! Unfortunately. Maybe, just because water plant are mountain located, and water temperature are continualy about 5 Celsius degree...

  13. The Florida drinking water rules list ion exchange, reverse osmosis, and lime softening (for systems with 500+ service connections) as best available treatment options for nickel.  However I do not have experience with it since we do not experience the same problem.

    2. This problem is very rare. So all we have lack of experience. We done so much trial's , found few solutions, but all are expensive. We are continue to looking for some effective but less expensive technology...

      Thank you
