Donaldson is set to acquire Ultrafilter International US-based Donaldson Co Inc has signed a definitive agreement to acquire 100% of the shares of German company Ultrafilter International AG for 72 million. Ultrafilter represents a strategic fit for Donaldson. According to the US company’s president and CEO Bill Van Dyke, Ultrafilter satisfies all three dimensions of Donaldson’s diversification strategy. It expands its presence in industrial markets, focuses on replacement parts, and the majority of its revenues are outside of the USA. This means that in a single transaction the company has reduced its dependence on mobile diesel engines, new capital equipment and the US economy, creating a more balanced portfolio and enhancing the stability of its performance over time. The two organizations are expected to enhance each other’s respective expansion in the US, Asian and European markets.
Ultrafilter also adds to Donaldson’s diversified portfolio of filtration businesses and provides another building block for the filtration capabilities that the company now offers to its industrial customers in dust and mist collection and hydraulic filtration. With roughly US$100 million in sales, Ultrafilter designs and manufactures components, replacement parts and complete systems for the compressed air purification industry. It has posted average revenue growth of 14% over the last five years – clearly above the pace of industrial manufacturing. Its products include compressed air filters and a wide assortment of replacement filters, refrigeration and desiccant dryers, condensate management devices and after-sale services. For more information, contact: Donaldson Co Inc, 1400 West 94th Street Minneapolis, MN 55431, USA. Tel: +1 952 887 3131, Fax: +1 952 887 3005.

Seprotech wins major government contract Canadian water and wastewater treatment systems manufacturer Seprotech Systems Inc has been awarded a contract by the Government of Canada valued at C$6.0 million over three years. The contract covers the repair, overhaul and other related services for sea water desalination systems aboard Canadian Naval vessels. The company will refurbish 18 desalination systems for the Canadian Navy. These systems are used to supply drinking and general-purpose water for the ship and its crew. The details of the contract, which also includes an option that allows it to be extended for a further two years, were finalized between the company and the Department of Public Works and Government Services Canada. For more information, contact: Seprotech Systems Inc, 2378 Holly Lane, Ottawa, Ontario K1V 7P1, Canada. Tel: +1 613 523 1641, Fax: +1 613 731 0851.
High-temperature polymer membrane captures CO2 What is claimed to be an economical technology for the separation and capture of carbon dioxide from industrial processes is being developed by the US Department of Energy’s (DOE) Los Alamos National Laboratory. Scientists at the laboratory are developing a new high-temperature polymer membrane to separate and capture carbon dioxide, preventing its escape into the atmosphere. Its use could lead to a significant reduction in greenhouse-gas emissions to the atmosphere. This work is part of the DOE Carbon Sequestration Programme’s mission to reduce the amount of carbon dioxide that is emitted into the environment from industrial processes. At a recent conference held in the USA, Jennifer Young, principal investigator for Los Alamos’ carbon dioxide membrane separation project, presented data on a new polymericmetallic membrane that is operationally stable at high temperatures. Young’s team developed the hightemperature membrane based on the polymer
polybenzimidazole, combined with a porous metallic support. According to Young, the resulting composite membrane has the highest operating temperature of polymer-based membranes (at 370°C) that has ever been demonstrated. It is also chemically resistant, and is easily processed. The unique combination of metallic support and polymer film, to form thin-film composite membranes, also allows the membrane to be effective at higher pressures than conventional membranes. Young says that current technologies for separating carbon dioxide from other gases require that the gas stream be cooled to below 150°C, which reduces energy efficiency and increases the cost of separation and capture.
