Dow Microbial Control Announces Regulatory Approval of Biocide

THPS now available in U.S. for water treatment applications

Dow Microbial Control has received regulatory approval in the U.S. for the antimicrobial THPS (tetrakis hydroxymethyl phosphonium sulfate) for water treatment applications. AQUCAR THPS 75 Water Treatment Microbicide is a biocide aimed to reduce the growth of algae, yeasts and mold in process waters used in various industrial applications. The product has been available in other parts of the world since September 2006.

“As the global biocides industry leader, we are pleased to provide our U.S. customers with another strategic tool to combat microbial contamination to achieve product performance and sustainable operations,” said Nanette Hermsen, strategic marketing manager with Dow Microbial Control. “Good, quality water is becoming scarce and expensive. AQUCAR THPS 75 provides another key biocide for gas and oil and water treatment applications, helping gas and oil service companies increase production and increase asset integrity.”

The company said AQUCAR THPS 75 is particularly effective against sulfate-reducing bacteria, which often are problematic in enhanced oil recovery operations like injection water treatment, top-side systems, pipeline protection and storage. THPS is able to not only kill microorganisms, but also reduce hydrogen sulfide concentrations and dissolve iron sulfide, the company said. It can be used in both acid and alkaline environments and is readily biodegradable.

“Dow Microbial Control provides unmatched global reach of technical and regulatory support,” said Mike Enzien, lead research and development specialist with Dow Microbial Control. “Using science and technology, like Dow’s patent-pending TAUNOVATE anaerobic high-throughput testing, we can help our customers optimize biocide treatments by matching the distinct chemical and environmental conditions of customers' systems, which, in turn, helps to protect equipment and assets from damaging and costly effects of microbial attack.”
