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?
Open Question to the Forum!!!
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..
Published by Qaisar Iqbal
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.

The most appropriate and efficient technology for the removal of low concentrations (ppm) of nickel is ion exchange adsorption.
Published by Carlos Henrique Catunda Pinto, Professor and Researcher at UERN - Brazil
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.

Best to do a little enhanced coagulaton rather that going beyond your existing system, which usually will make your life more complicated.

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

is your thesis public? could i get a copy? thanks

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

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.

could i get information on approximate cost (for small communities)? thanks.

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

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.

Differentiate streams i n two try One stream with RO then mix both streams to get desired levels.
Published by Vinayak Gade, Chief Consultant at Gagangadh Consultech
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.

Sodium sulfate, not sulfuric acid!!
Published by Joseph Cotruvo, President at Joseph Cotruvo & Associates, Water , Environment and Public Health
These gentlemen are all correctIon Ion exchange, RO, GAC Adsorption(limited life), and coagulation then filtering.
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.
Published by Miroslav Besermenji, IN-VET INSTITUTE - President
ion exchange works but it is expensive and more energy cost. filter with chemicals or adsoption.
Published by Nancy Yang, Process engineering at Nordic Water Products AB
Yes, but adsorption are short efective, too.
Published by Miroslav Besermenji, IN-VET INSTITUTE - President
See WHO Guidelines for Drinking Water Quality 4th edition, p 397. Conventional coagulation works. Cation exchange also if necessary.
Published by Joseph Cotruvo, President at Joseph Cotruvo & Associates, Water , Environment and Public Health
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...
Published by Miroslav Besermenji, IN-VET INSTITUTE - President
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.
Published by Kim Neumann, Environmental Scientist Senior at JEA
The ion exchange adsorption process is very efficient, removing more than 99% of the nickel present in the public water supply.
Published by Carlos Henrique Catunda Pinto, Professor and Researcher at UERN - Brazil
Not, after our's tests. Max 70%
Published by Miroslav Besermenji, IN-VET INSTITUTE - President
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
