Anthony Bennett investigates the use of membrane technology in the fine chemicals industry – in the production of the chemicals themselves and also in the generation of process water and the treatment of effluent from chemical synthesis. 06 July 2010
Reverse osmosis technology has been used to recover valuable water from the cooling towers of the Datong Power Plant in Shanxi, China for use as a source of boiler make-up water. 06 April 2010
In his series of articles, Ken Sutherland covers new developments in a number of broad classes of filtration and separation. 24 February 2010
Despite the tight credit markets and challenging global economy, 2008 saw further consolidation within the filtration and separation sector. Listed below are the mergers and acquisitions that took place during 2008. 18 December 2009
Ralf Krüger from inge watertechnologies describes the growing popularity of ultrafiltration as pre-treatment in seawater desalination and looks at its successful application at an Italian power plant that required an efficient and low-maintenance ultrafiltration solution. 18 March 2009
A relatively recent development in membrane processes, Ken Sutherland looks at the rapidly expanding field of nanofiltration, its characteristics and its applications. 18 March 2009
There is increasing inter-dependency between new filtration technologies and renewable energy. In this article, Dr Mike Coffey looks at the growing use of renewable energy in systems such as wastewater treatment and biogas combustion, and integrating sustainable power into energy intensive reverse osmosis systems. 18 March 2009
Engineers set out to design a cartridge filter that could work efficiently to provide compressed air to international quality standards. The design involved looking at critical areas, such as air flow management, filtration media selection and construction and the efficient removal of coalesced liquid. 04 March 2009
The elimination of total organic solids (TOC) from feedwater is vital to ensure the long term performance of a high-pressure boiler. At a power plant in Thailand, a ‘two pronged’ application of UV technology from Hanovia reduced TOC by 68% and helped the plant on the way to meeting the country’s growing electricity demand. 03 March 2009
