“…14,15 Nowadays, RSM has been widely used for designing experimental models and determining the optimum experimental conditions. [16][17][18][19] In this study, the objective was to characterize the main parameters in the bioelectrochemical process, including the V/S ratio (volume of the BES/size of the electrode ratio), interval (D) (distance between the anode and cathode) and position (P) (proportion of the electrodes immerged in the sludge). The experiments were conducted in a batch assay to optimize the V/S ratio, interval and position to achieve the best performance in pollutant transformation.…”

“…For this purpose, a simple estimation of the nutrient requirements of the biomass as a function of the nitrogen load to be treated can be performed and compared against the influent nutrient concentrations to assess whether external addition is necessary to support the biological growth requirements and conversion rate. In some cases the external dosage of particular micronutrients beyond the minimal requirements can enhance the kinetics of a specific microbial population as recently reported in the case of iron dosage to anammox cultures (Chen et al, 2014;Bi et al, 2014).…”

PrefaceWastewater treatment is a core technology for water resources protection and reuse, as is clearly demonstrated by the great success of its consequent implementation in many countries worldwide. During the last decennia scientific research has made vast progress in understanding the complex and interdisciplinary aspects of the biological, biochemical, chemical and mechanical processes involved. It can be concluded that the global application of existing knowledge and experience in wastewater treatment technology will represent a cornerstone in future water management, as expressed in the Strategic Development Goals accepted by the UN in September 2015.Only about one fifth of the wastewater produced globally is currently being adequately treated. To achieve the goal for sustainable water management by 2030 would require extra wastewater treatment facilities for about 600,000 people each day. I am convinced that this book will make its own significant contribution to meeting this ambitious goal.In the near future, most of the global population will live in cities and in low and middle-income countries, where most wastewater is not adequately treated. Probably the most limiting factor in achieving the goals for sustainable water management is the lack of qualified, well-trained professionals, able to comprehend the scientific research results and transfer them into practice. It is therefore of prime importance to make currently available scientific advances and proven experiences in wastewater treatment technology applications easily accessible worldwide. This was one of the drivers for the development of this book, which represents an innovative contribution to help overcome such a capacity development challenge. The book is most definitely expected to contribute to bridging the gaps between the science and technology, and their practical applications.The great collection of authors and reviewers represents an interdisciplinary team of globally acknowledged experts. The book will therefore make a major contribution to establishing a common professional language, enhancing global communication between wastewater professionals. In addition, the authors have linked the description of the scientific basis for wastewater treatment processes with a video-based online course for the training of students, researchers, engineers, laboratory technicians and treatment plant operators, demonstrating commonly accepted experimentation procedures and their application for lab-, pilot-, and full-scale treatment plant operation.From the perspective of the IWA this book also has the great potential to enhance the development of a new generation of researchers and enable them to communicate on a global scale and beyond their specific field of expertise. Both aspects are urgently needed to develop adapted solutions for specific local conditions and to make them globally available for implementation.There has been a trend for some time that scientific research and practice have been growing apart from each other.

“…Research on heavy metals has achieved abundant outcomes ( 96 also focused on the short-term impact of anammox IC 50 . However, Chen et al 97 added some metal ions to the reactor, namely Fe 3+ (6.61 mg L À1 ), Cu 2+ (1.18 mg L À1 ), and Ni 2+ (1.11 mg L À1 ); it was found that the anammox nitrogen removal rate increased by 50%, and this phenomenon showed that metal ions may have positive inuences on anammox bacteria. 98 Studies have found that low concentrations of Cu 2+ (0.05 to 0.56 mg L À1 ) will inhibit the activity of denitrifying bacteria, while Zn 2+ will promote the growth and reproduction of denitrifying bacteria at lower concentrations.…”
