The status of solid liquid separation technology within chemical
engineering and as a subset of the wider field of particle technology
is discussed in the introduction and the difficulties that beset
research into design methods in this area are described.
All the writer's publications relate to the subject of solid 1iquid separation technology and are reviewed and presented in this submission.
Solid liquid separation technology may be subdivided into pretreatment,
central treatment and post-treatment and the work is presented
under each of these headings.
The pretreatment area is itself divided into two sections. The first
one deals with lamella separators and the second with hydrocyclones
used as devices for increasing the concentration of suspensions prior
toa cake filtration stage. Some unpublished work is included in the
chapter on lamella separators.
The central treatment operation discussed is cake filtration and
the work presented refers principally to the development and use of
1 aboratory test methods.
Post-treatment operations. are discussed in the context of the development
of design methods for the forced gas del iquoring of filtercakes.
Fina lly, suggestions are made about direct ions in which future
profitable effort might take and the author's own programme of
further work is outlined.
Submitted in partial fulfilment of the requirements
