giving equipment surveys, mechanisms and applications
for each type.

Volume
GC V Part 1 Introduction.
The wide range of gas cleaning
categories which are included in this manual will be
outlined, as well as the influence of legislation on
their usage. A brief resumé of the limits of each category
will aid in rapid evaluation for a given application.
Volume
GC V Part 2 State of the technology.
This part
includes pre-filter technology, HEPA and ULPA filters,
fibrous filters, candle filters made from rigid metal
or ceramic media, and those used for high temperature,
nuclear and aerospace applications. Magnetic and granular
bed filtration are also covered. New materials in particular
are dealt with, including modern HEPA media, new ceramics,
and high specification metallic materials.
Separations
at high temperature and pressure, in granular and fluidised
beds which have been covered in detail in existing reports,
have been updated and incorporated into the manual.
Old style
SARs which exist on gas cleaning under hostile and difficult
conditions, and under stringent conditions, have and
also been incorporated into the manual.
A review
of current filter designs, seals and media is included.
Volume
GC V Part 3 State of the science.
The focus here is on the
theory of particle collection in filters and include
all major phoretic effects and combined mechanisms.
It thus provides a comprehensive review of particle
collection theory. Models for predicting performance
are also reviewed.
Volume
GC V Part 4 Industrial application and design.
Design procedures in depth
and rigid filters are largely based on experience and
media selection expertise, but this is based on a number
of manageable rules. These will be reviewed and presented
in a usable form.
