Wastewater microbiology

---

I would like to mention some of the changes and additions that have been included in the
third edition of Wastewater Microbiology. In general, every chapter of the book has been
revised (up to July 2004) to include the latest developments in the field, and I will highlight
only the major ones.

A review of the most important molecular techniques has been added to Chapter 1,
while the most recent methodology for measuring microbial biomass in environmental
samples is described in Chapter 2. New developments in enhanced biological phosphorus
removal (EBPR) are covered in Chapter 3. Chapter 4 covers new findings on old and emerging
(e.g., Helicobacter pylori, Cyclospora, Microsporidia) microbial pathogens and parasites.
Much progress has been made concerning the detection of Cryptosporidium and
Giardia in environmental samples, including wastewater. The improved methodology is
also covered in Chapter 4. As regards disinfection of water and wastewater, research
efforts are now focusing on UV disinfection in industrialized countries and on the use
of solar radiation in developing countries (Chapter 6).

Armed with new molecular tools and microsensor/microelectrode technology, investigators
are making progress in understanding the microbial ecology and the surface properties
of activated sludge flocs. The methodology used is similar to that used in biofilms.
These advances will help us to better understand the flocculation process in activated
sludge (Chapter 8). Concerning bulking and foaming in activated sludge plants, most of
the recent studies have focused on the characterization and phylogeny of filamentous
microorganisms (Chapter 9).

In the last few years we have witnessed an increased interest in biofilm microbiology.
Biofilms develop on biological and nonbiological surfaces and are ubiquitous in natural
aquatic environments and engineered systems (e.g., fixed-film bioreactors). Their beneficial
role in fixed-film bioreactors has been known for years (chapter 10). However,
the impact of biofilms on drinking water distribution systems has been the subject of
increased research activity around the world (chapter 16). This interest is further heightened
by the findings that biofilms are the source of medical problems such as dental
plaques or colonization of artificial implants, leading to increased rate of infection in
patients. The discovery of communication among members of the biofilm community
(i.e., quorum sensing using signaling chemicals such as homoserine lactones) may lead
to potential means of controlling biofouling of surfaces.

Chapter 13 shows that new procedures, particularly molecular techniques, have helped
shed light on the phylogeny of methanogens and other Archaea.
Part D (Microbiology of Drinking Water Treatment) of the third edition now comprises
three chapters instead of two as in the second edition. The third chapter (Chapter 17) introduces
the reader to bioterrorism microbial agents and their potential impact on drinking
water safety.

In Chapter 18 (Biotechnology of Waste Treatment: Pollution Control Biotechnology), I
have added some information about membrane bioreactors (MBR technology), while in
Chapter 21, new developments in the area of bioremediation have been included.
Finally, in Chapter 23 (Wastewater Reuse), I have made an attempt to introduce the
reader to the microbiological aspects of the treatment of wastewater effluents by
natural and constructed wetlands and by the use of attached algae for polishing wastewater
effluents.
