Separation of Boron from Liquid Media

B

Boron The process for removing boron can depend on the type of application. Please select one of the applications below to refine the recommendation.

Municipal & Desalination

Boron is a natural element that is prevalent in ground water from areas with volcanic geology, present in all sea water (3–5 mg/L) and is used in commercial products such as detergents. Mildly toxic to humans but frequently very toxic to plants, especially to citrus varieties, boron is regulated in most regions of the world. The World Health Organization (WHO) guideline for boron content in drinking water is 0.5 mg/L (ppm). AMBERLITE™ PWA10 Resin is a boron selective ion exchange resin that can help you to meet your drinking water and irrigation water requirements.

This resin may be subject to drinking water application restrictions in some countries. Please check the application status before use and sale. For more information see our regulatory information.

Power Generation

Environmental regulations have driven the installation of flue-gas desulfurization (FGD) systems in many fossil fueled power plants over the recent past. The lime solutions used to scrub the sulfur out of the flue gas also collects many of the trace contaminants found in coal. These include arsenic, boron, mercury and selenium. New regulations will require the treatment of the FGD blow down water prior to discharge. Dow Water & Process Solutions offer highly selective ion exchange resins and media to remove trace contaminants found in FGD blow down water.

Chemical & Petrochemical

Magnesium Chloride Brine Purification

Magnesium and its compounds are produced from seawater, well and lake brines, and bitterns, as well as from minerals like magnesite.

High purity magnesium oxide for sintered magnesia refractories is made by pyrohydrolysis of magnesium chloride brine. The presence of boron in the magnesium chloride (MgCl2) brine is undesirable because boron embrittles the magnesia ceramics during drying operations. The presence of boron also prevents the coalescence of magnesium metal during electrolysis of fused magnesium chloride salts. In both cases, boron can be removed from the magnesium chloride brine by using AMBERLITE™ IRA743 Resin, which is a boron-selective resin. AMBERLITE IRA743 is capable of reducing boron concentrations from around 100 ppm to <10 ppm in 12% magnesium chloride.

Industrial Waste Water

Sometimes mildly toxic to humans and often very toxic to plants, especially citrus varietals, boron is regulated in most regions of the world. A major process contaminant in such applications as semiconductor manufacture, boron is a natural element prevalent in ground water from areas with volcanic geology. It can be found in coal and other fossil fuels and is used in commercial products such as detergents. Dow Water & Process Solutions manufactures AMBERLITE™ IRA743 Resin, a boron selective ion exchange resin to help meet discharge or product requirements.

Oil Field Water

Globally, shale gas and oil is becoming an important source of energy. It is obtained through hydraulic fracturing, also known as fracing, and the development of horizontal drilling technology. The fracing process results in large quantities of flow-back and formation water that must often be treated before recycle, reuse or discharge. Dow Water & Process Solutions offers a wide range of water treatment technologies and the technical expertise to help you treat the water for fracing and produced by shale gas extraction.

A major process contaminant in such applications as semiconductor manufacture, boron is a natural element prevalent in ground water from areas with volcanic geology. It can be found in coal and other fossil fuels and is used in commercial products such as detergents.

Boron occurs in nature in its oxidized forms as boric acid and its salts. Boric acid is a very weak acid and acts much like silicate so it is difficult to remove from water. It has a very low selectivity for an anion exchange resin so resin capacity will be limited by the presence of other anions.
