shutdown
A paper mill based in southern England producing 200,000 tonnes of paper every year requires large amounts of softened boiler feed water in order to generate its own electricity as well as steam, for process use. Gradually the silica levels in its borehole supply increased, making it necessary to blowdown the boilers more frequently, and resulting in higher energy and chemical costs. Eventually the original de-alk/sofiening plant could not cope with the rising levels of silica as well as make-up water flow rates. Permanent damage to the boilers could have occurred, or even the mill’s eventual shutdown. Ecolochem International, a leading water treatment company, was called in to solve the problem on an emergency basis. Within a few hours, its engineers had supplied and were operating an emergency Mobileflow demineraliser system which produced water of less than 5 ppb silica and conductivity less than 0.06 @/cm.

Guide
to best practice
The UK’s Metal Finishing Association is preparing a ‘Good practice guide on vapour degreasing’ as part of the UK government-funded Environmental Technology Best Practice programme. Vapour degreasing is one of the most widespread methods of cleaning components. However, there are both environmental and health and safety concerns over the consumption of organic solvents and the release of these and other volatile organic compounds (VOCs) into the atmosphere. To comply with current legislation, users need to be aware of the problems and employ ‘best practice’ in the operation of their existing equipment. The alternative is the enforced purchase of expensive new plant which meets all the regulations. The guide will deal with the 358

abled the paper mill to continue operation as normal, as well as reducing the levels of silica present in the boiler chemistry. This also gave the paper mill management time to contemplate a longer-term solution. After considering various options, it decided to use Ecolothem’s permanent on-site equipment because it was the most cost-effective, simple to use and flexible solution with no capital investment required. Ecolochem provided two MobileFlow 500 coagulation filtration systems, a MobileRO reverse osmosis system and a MobileFlow 500 softening system. The mill can now easily produce high-quality boiler feed water cheaply and safely in the knowledge that if the borehole water quality ever changes again, Ecolochem can take care of the problem.

conference
Lutz Bergmann is organising an independent international conference on dry, air and gas filtration, to take place 3/4 October 1995 in Osaka, Japan. Many industry-leading companies will be reporting on the ‘state-of-the-art’ in gas filtration. Many different aspects in this field will be discussed, including the importance of fabric filtration in incineration. The removal of particulates, heavy metals, dioxins and furanes is essential, and especially so in Japan, which has 1800 municipal incinerators to cope with the waste from its densely

crowded population. In addition, leading fibre companies will share their experience and application data from utility and industrial coal-fired boilers. Also being covered will be activated carbon filters, automotive cabin filters and developments in microfibres. Filter Media Consulting Inc, PO Box 2189, L&range, GA 30241. 2189, USA.

vibratory
sieve
Among the latest sieving and straining equipment to be demonstrated at Interbulk (at the NEC, Birmingham, UK 6 -8 June) will be the new Russell Finex Compact 900 high-performance vibratory sieve, which has been especially designed for use where headroom is restricted. Featuring a 900 mm diameter screen, the new machine is ideal for applications requiring higher throughputs than the existing Compact 600, which has a 600 mm screen. Also on show will be the latest, improved Russell Vibrasonic deblinding system, which will be seen integrated into the Compact range of sieves. The Vibrasonic System utilises a unique combination of ultrasonics and conventional vibration to give exceptional precision, dramatically increased throughput, reduced downtime and longer screen life. By applying an ultrasonic frequency directly to the separator mesh, the Vibrasonic
on show
breaks down surface tension, effectively making the wires friction-free. Completing the display will be the Russell Finex self-cleaning strainer to meet today’s environmental and productsafety requirements for totally enclosed liquid/solid separation systems. Use of a Russell self-cleaning strainer reduces downtime to a minimum because its unique wiper-blade assembly keeps the microscreen clear of oversize solids, ensuring continuous unrestricted liquid flow. The oversize gravitates towards a sump which incorporates a solids discharge valve. Constructed from stainless steel throughout, the machines are easy to maintain and are totally enclosed to protect the strained product from airborne and other contamination.
