Siemens Industry Automation Division entered into an agreement to acquire Cambridge Water Technology based in Cambridge, Mass. in an effort to expand its water and wastewater treatment business.

Siemens says this acquisition is an important building block to Siemens’ strategy of pursuing “leading-edge technologies with high customer value for municipal water and wastewater treatment as well as select industrial markets.” According to Siemens, the Cambridge Water Technology product line complements Siemens’s offering for biological wastewater treatment and clarification as well as drinking water treatment.

Cambridge Water Technology has marketed its products under the BioMag and CoMag brands, primarily in the municipal wastewater market. Additionally, the company has used its technologies in a number of industrial market applications and is investigating drinking water treatment applications. Its proprietary technologies are based upon what Siemens describes as a novel approach of using magnetite as a ballast to optimize the clarification process. Siemens says Cambridge Water Technology is the first company to successfully apply this type of technology to biological wastewater processes. Using the technologies can result in significant reduction in capital costs for capacity expansion and nutrient removal, as well as improvements in meeting turbidity requirements.

The planned acquisition will include global technology rights, but not Cambridge Water Technology’s current subsidiaries outside of the United States. BioMag and CoMag are trademarks of Cambridge Water Technology and/or its affiliates in some countries.

Cambridge Water Technology is expected to be combined with Siemens’ municipal wastewater business and will continue to operate out of Cambridge. The company’s senior managers, Charles Hamlin, Steve Woodard, and Andy Bishop, are also joining the Siemens business unit’s management team.
