Experts in filtration and separation

We advance and disseminate knowledge in the design and use of filtration and separation techniques in industry, commerce and other walks of life.

10 May – Regulatory and Technical Issues in Environmental Control
Runcorn, UK

The Filtration Society hosted another highly successful seminar at the Heath Conference centre in Runcorn in May.  Environmental issues, high on any political agenda at the moment, were a perfect vehicle to highlight the mission statement of the Society, which is to inform, refresh and advance filtration technologies.

The scene was set by Stephen Taylor from the Environmental Agency who introduced the current emissions and legislation standards.  The necessity for monitoring filter efficiency in air conditioning systems was then reviewed by Simon Tebb of TSI Instruments, who through the latest technology, was now able to quantify ‘sick building syndrome’.  The impact of the legislation on clean air and clean water was investigated by Tal Goldsworthy of Environmental Development Technology and Colin Deakin of GE Water and Process Technologies respectively.  An interesting insight was how media pressure could distort good science with regard to perceived health risks.

A fact not often appreciated is that over 80% of industrial processing involves metal catalysts so trace metal removal from liquid effluent is a very sensitive issue in the light of the latest stringent emissions legislation.  Kevin Treacher of Reaxa presented a fascinating talk on a novel, highly efficient metal scavenging system. Chris Withers of Caldo Engineering and Andy Startin of Madison Filter concluded the technical presentations by discussing hot gas filtration, not only to remove particulates but, by incorporating catalysts, to also remove toxic gases from incineration.

An important conclusion from most speakers was that, while ‘end of pipe’ solutions were an important step forward, only a fully integrated process design would ultimately deliver the environmental cleanliness desired by legislators and public alike.  The final presentation was a real wake up call to those involved in landfill waste disposal.  James Heath of Cyclerval Ltd reviewed the impact of economic and commercial issues in municipal waste management.  With the ever-increasing penalty per ton combined with a minimum of five years in planning and 25 years in payback through gate fees, the inability to quantify safety and commercial uncertainties could lead to financial disaster to those involved.  Financing the Channel Tunnel was cited as a good example of what could go wrong.

4 October – Preserving Profits With Automation of Filtration Technologies
Runcorn, UK

A Filtration Society symposium originally billed as one to optimise profits through automation, evolved into a glimpse of Tomorrow’s World as several of the speakers introduced the concept of remote monitoring through telemetry and via the internet.

This one-day event held on October 4th at the Runcorn Heath Conference Centre in the UK attracted an international gathering of both speakers and delegates keen to exchange ideas and information on the latest technologies for process optimisation. Several discussion points arose and there was very good audience discussion with presenters on many issues, including:

Operating companies overcoming their concerns about confidential process information being transmitted to third parties for remote monitoring, control and optimisation.

Operating companies overcoming their concerns about outsourcing the process operation and maintenance to companies that are ready to introduce automation systems as a means for increasing profitability – particularly the risk of it being unsuccessful.

Suppliers of service products such as filter media introducing automation products which cannibalise the base business due to longer product lifetimes.

Comparative monitoring systems can be as powerful as exact measuring systems for control, particularly in gas cleaning applications.

In a nutshell the range of automation systems presented varied from ‘Business as you think it’ to ‘Simplicity is the ultimate sophistication’.

The concept of remote monitoring by telemetry was introduced by Doug Harris of Pall International and Raymond Smalley of Westfalia Separator Ltd and exemplified by Kari Koskela of TEKES (Finland). Technological advances in control networks not only increase profitability by reducing manpower, but can detect imminent equipment failure so minimising expensive down time.

The seminar theme was developed by Andrea Dotti of Tyco Environmental Systems (Italy) and William Averdieck of PCME Ltd who illustrated the impact continuous monitoring can have not just on cost savings but on reduced emissions in baghouse filters.

With ever increasing legislation on environmental and safety issues, Russell Kaschula of GKD showed how automation in filtration processes involving large volumes of mercury contaminated water could protect both the operator and the environment.

Selection of the most appropriate equipment was admirably dealt with by Steve Tarleton of Loughborough University who presented a unique computer software program that charts the most effective route through a minefield of potential filtration and separation equipment (more information about the Filter Design Software can be found at

As with all Society symposia, question times provided a very useful exchange of ideas and the delegates retired with much food for thought! Bound notes of the symposium can be purchased from the Honorary Secretary.

22 November – Innovative Filter Media: Applications for Process Improvement
