Inorganic materials (for borate ion in water)

Hello,

One of our Japanese partners are looking for waste water solution and technology.
Below you may find the details of the described problem and the needs.
I would appreciate if you could reccomend me on a company that can provide a solution to solve this problem

As one of the subjects that the Japanese company is working on is about the waste water treatment methods coming out from the factories such as Ceramics, Glass, Chemicals, Cosmetics & Medicines.  They present methods are well controlled for chemicals such as Fluosine, Cadmium, Mercury to take out from the contaminated ground water, but they need to find some new material which does the precipitation or abosorption of Boric(H3.BO3). The contaminated water running out from the factory  under ground piping (1-4 meters depth) contains Boric ( several mil grams per liter - several hundreds mil grams per liter) for which they want to find the better way to take out.  They presently uses Iron-Grain (Fe) for the purpose and it works for others such as Trichiloroethylene (CHCL=CCL2), but does not work for Boric treatment.

So far the Japanese are trying several other materials, for example, Silica gel. experimenting it with( H3BO3(10mg/l B) water container.  They can not disclose all other material names that they are trying at this moment, but they are not yet successful in resolving this issue to them satisfaction.  I hope the aboves are clear enough for you and you can find something new materials or new methods to offer the Japanese company.

Thank you.

If you or your Japenese partners haven't done so, do a Google search for "boron removal from water". There are several hundred thousand sites to review, ranging from resin treatment to reverse osmosis to application of hydrotalcite-like compounds.

Boron removal from water is difficult.  Ion exchange and reverse osmosis is typically used because classic coagulation and flocculation do not work well.  Boron is one of those compounds that is becoming more strictly regulated and the technology to remove it cost effectively is limited.

A breakthrough in this area would be a very good advancement for water treatment.
