Page 14 - Membranes for Industrial Wastewater Recovery and Re-Use

Preface xi

already very well served in such areas, and in particular extensive systems, by
the seminal work of Asano and the recent eclectic publication by Lens et al.
(Table 2). Finally, although the principles of water pinch analysis are described
in Section 4.2, this is only to enable an understanding of how it can be used.
Once again, there are other texts available that comprehensively describe the
methodology and its derivation (Mann and Lui).
It is hoped by the editors, however, that anyone interested in industrial
wastewater recycling, including problem holders and membrane suppliers as
well as students and academics studying in this area, will find this book useful. In
particular, the book is meant to provide a practical aid to those readers with an
interest in actually selecting, installing and/or designing systems for recovering
and reusing industrial effluent. To his end, there is one chapter dedicated to
design (Chapter 4), and in particular computer-aided design, based on
commercial packages, of reverse osmosis arrays (Section 4.1) and water
networks (Section 4.2). There are also eleven individual case studies, covering a
range of applications, which are discussed with reference to design and
operational facets of the water recycling treatment schemes (Chapter 5). Whilst
not all industrial sectors where water recovery and reuse takes place are covered
in this book (it is cxtremely difficult to extract all information pertaining lo
industrial water quality, let alone water reuse) as much detailed as has been
made available is reported in the book. Lastly, the book is very much biased
towards engineering practice, rather than scientific study. Data pertaining to
membrane process performance in Chapters 3 and, more especially, Chapter 5,
are based almost entirely on existing pilot or full-scale systems, rather than
bench-scale studies or theoretical predictions.
As with any piece of work the editors would welcome any comments from
readers, critical or otherwise, and our contact details are included in the
