The next in Ken Sutherland's series of articles, on the smaller end-use equipment application sectors, features the use of filtration equipment in the manufacture of machinery, including the production of transport equipment as well as equipment usage in the operation of transport systems. The sector is not actually small in volume terms, but is considered in this series of articles because of its use of only a relatively narrow range of equipment types. 13 July 2010
Winemaking by-products are a low-cost and rich source of valuable phenolic compounds with widely recognised health benefits. Membrane separation processes are ideal for recovering these compounds, ensuring high quality of the extracts produced. As a result of the gentle nature of membrane processing, the final products can justify the label ‘natural’, which is essential for most food and cosmetic markets. Carla Brazinha explains. 08 April 2010

As we are all aware, water is becoming a scarce and expensive commodity. The beverage and food industries, looking to increase the recycling of their process water to keep costs low, are turning towards membrane bioreactors for water treatment. Alfa Laval's Detlef Ahrens explains how it works. 25 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
The Harnaschpolder wastewater treatment plant, based in the Netherlands and run by Veolia, is a great example of a modern filtration system with a look to the future. Filtration+Separation visited the plant to find out how it operates. 18 March 2009
A team from the Belgian company Bekaert explain the development of an enhanced surface filter medium based on short metal fibres, specifically designed for applications in the food and beverage and chemical and pharmaceutical industries. 18 March 2009
The production processes for beverages demand that the final result is a drink that meets the expectations of customers, both visually and gastronomically. Ulrich Braeutigam of Sartorius explains how the last step in this process could be the most important, and how a new product could help. 18 March 2009
Peter Rose of Alfa Laval takes a look at one of the growth areas of biopharmaceutical filtration and separation: the harvesting of mammalian cells to produce new drugs and medicines. The article examines the origines of the technology used in this sector of the industry, and considers recent developments. 18 March 2009
Lyco Manufacturing was called upon to create a screening system to deal with the troublesome organic contaminants that are released as a result of turkey processing and can lead to companies having to pay additional discharge fees. 04 March 2009
A major food company was experiencing screen blockage problems when filtering rapeseed oil for biodiesel production. It decided to purchase a Self-Cleaning Filter from separation specialists Russell Finex. By installing the filter the company hoped for an increase in productivity and improvement in product quality. 03 March 2009
Crossflow filtration has been used for many years in food and beverage applications. Now French filtration specialists SIVA have improved the technology, ensuring that this method of filtration can meet oenophiles’ high standards for wine quality – and save energy in the process. 03 March 2009
