Cambridge Water Technology is a well established, well funded, United States headquartered business that is devoted to the development of high performance, low cost solutions for the production of potable/process water and the purification of wastewater. Based on innovative technologies developed at the Massachusetts Institute of Technology, and successfully demonstrated at wastewater treatment facilities such as Concord, MA, Charlton, MA and Marlborough, MA, as well as over 20 municipal water and wastewater plants in China, CWT systems truly provide the next generation of water clarification, filtration and biological treatment for municipal and industrial applications. These systems deliver much cleaner water, at lower capital and operating costs, and with greater reliability than alternative potable or wastewater treatment systems.
Cambridge Water Technology’s core technology, CoMag™, represents the culmination of over 30 years scientific development and commercial application of magnetic-based technologies. Crucial among these is High Gradient Magnetic Separation (HGMS), a technology of removing magnetic materials from a water stream.
The company’s founders began applying HGMS concepts and the application of magnetically enhanced coagulation-separation technology to wastewater in the early 1990s. In 1997, the company filed for a patent covering the CoMag™ process and in August of 2000 was awarded a patent for removing solutes from a fluid stream using magnetically conditioned coagulation.
 The 1.25/4.0 MGD CoMag™ Plant goes online in October 2007 |
In addition, CoMag™ has been endorsed by the Massachusetts Strategic Enviro-technology Partnership (STEP) and the Massachusetts’s Department of Environmental Protection. The process received a 1999 EPA award for innovative environmental technology and on March 20, 2003, CWT’s chairman and chief technology officer, Peter Marston, received an Earth Trustee Award presented at the United Nations by the Earth Society Foundation for the development of CoMag.
The high performance, reliability, and cost effectiveness of CoMag™ – especially for the removal of Phosphorus - has been recognized by many municipalities as a cost effective alternative to conventional tertiary water treatment systems.
The Town of Concord, Massachusetts is nearing the completion of a 1.25/4.0 MGD CoMag™ system to meet its impending NPDES 0.1 mg/L TP limit and anticipated 0.05 mg/L requirement of the Town’s next permit. This plant is scheduled to go online at the end of October 2007.
 CWT's 2.0 MGD mobile plant operation in China |
CWT has also recently entered the Chinese market seeking to serve the large and burgeoning need for municipal and industrial wastewater treatment. With strong in-country leadership, CWT has demonstrated at pilot and demonstration scale the ability of CoMag to provide high performance and effective solutions for industrial and municipal water and wastewater applications.
This has resulted in the sale of a 1.3 MGD plant to treat the oily wastewater created in the Shengli oil fields of Sinopec, the country’s second largest oil producer. In this application, CoMag™ is clarifying wastewater ladened with 1000 mg/L of oil to non-detect levels – another testament to the process’ ability to remove particulate from a water stream. This plant will be online by September 2007.
In addition, CWT is now operating a 2.0 MGD mobile CoMag™ plant in China. This is effectively our Concord plant on a truck, a testament to the scalability of CoMag as well as its compactness, low cost and high productivity.
CWT operates research, laboratory, design, engineering, fabrication and sales facilities in Massachusetts and Maine and in Qingdao, China.
