The books currently available on this subject contain some elements of physical-chemical treatment of water and wastewater but fall short of giving comprehensive and authoritative coverage. They contain some equations that are not substantiated, offering empirical data based on assumptions that are therefore difficult to comprehend. This text brings together the information previously scattered in several books and adds the knowledge from the author's lectures on wastewater engineering.
The last book covering a part of this subject has come four years ago (Vymazal, J., and Kropfelova, L., 2008. Wastewater Treatment in Constructed Wetlands; Springer, New Yark) and the one prior to that six years ago (Crites R. W., Middlebrooks, E. O., and Reed, S. C., 2006, Natural Wastewater Treatment Systems; CRC Press, Boca Raton). Both are excellent treatises but neither covers systems based on 'nutrient film technique' even as it is in this segment that most spectacular advances are currently occurring. Moreover, the state-of-the-art in all systems has advanced significantly since these books came out. The proposed book would, therefore, be much more comprehensive as well as up-to-date.

Recent technical innovations and significant cost reductions have sharply increased the potential for using Membrane Bioreactor (MBR) technology in municipal wastewater treatment. MBR technology displays several advantages compared to the traditional activated sludge processes, such as high effluent quality, limited space requirement and with the possibility of a flexible and phased extension of existing waste water treatment plants. Membrane Bioreactors for Municipal Wastewater Treatment describes the results of a comparative research programme involving four leading membrane suppliers: Kubota (Japan), Mitsubishi (Japan), X-Flow (Netherlands) and Zenon (Canada). Each supplier provided a pilot to represent a suitable scale - right up to full scale. These pilots were operated and optimised in the course of the research programme to achieve the best operating window under different operating regimes. The research focussed on the functionality of the membrane, the biological treatment, membrane fouling, achieved effluent quality, and system operability as well as other factors. In a number of side studies the required pre-treatment, membrane fouling/cleaning, energy usage, effluent quality and sludge processing were also addressed. The comparative pilot research was carried out by DHV Water on location at the wastewater treatment plant at Beverwijk in the Netherlands.
Two young people, two stories. One country. Southern Sudan, 2008: Nya is going to the pond to fetch water for her family there and back, twice a day. She walks for eight hours every day to perform this seemingly simple task. Southern Sudan, 1985: Salva is walking away from his ruined village to find safety if there is any safety in his war-torn homeland. His journey across Africa to Ethiopia and then to Kenya and beyond will take many years. Salva is a survivor, and his story goes on to intersect with Nya's in an astonishing and moving way. This mesmerizing dual narrative by award-winning author Linda Sue Park is a fictionalised account of true events and shows us that in a troubled country, determined survivors may find the future they are hoping for.
Following an introductory overview, Hyperthermia In Cancer Treatment: A Primer comprehensively describes the biological reasons for associating hyperthermia with radiation and chemotherapy and the biological and clinical effects of hyperthermia on cancerous and normal tissues. The volume's 20 chapters are arranged in three principal parts: physical and methodological studies, biologic principles, and clinical studies.
