Salt Splitting

Ionomr membranes have revolutionary chemical stability and when paired with their high selectivity and proton blocking characteristics, they enable the generation of high strength chemicals from waste industrial brine streams. Ongoing testing demonstrates tolerance to oxidizing impurities such as chlorine and stability under high current, providing strong lifetime indications to further improve process economics.

Salt-Splitting Electrolysis is a cost-effective solution for the rapidly expanding niche markets of acid and caustic recovery and treatment of neutralization waste products.By combining industrial waste treatment with process chemical regeneration, the economics of the water treatment systems are drastically improved.

Typical applications include:

Splitting of sodium sulfate (Na₂SO₄) produced in the pulp and paper industry or resulting from precipitation of metal-sulfates by sodium hydroxide in the mining, metals, and recycling industries to regenerate sulfuric acid (H₂SO₄) and sodium hydroxide (NaOH).

Splitting of organic tetramethylammonium (TMA) products generated in the semiconductor industry to regenerate tetramethylammonium hydroxide (TMAH) and a carrier acid.

Rapidly expanding market for production of high purity lithium hydroxide (LiOH) directly from lithium sulfate (Li₂SO₄) with combined with regeneration of the sulfuric acid carrier (H₂SO₄).
