Book Description
Acknowledging that resource efficiency as well as ecosystem protection are crucial goals to tackle has led to a deep rethinking in the way wastewater has been dealt with up to the 20th century. Indeed, pollution reduction to harmless levels has been the main focus of conventional wastewater treatment plants which have deployed effective and reliable solutions to get rid of suspended and dissolved pollutants. Nowadays, those same wastewaters are looked at as a mine of valuable resources that are to be harvested from the sewage through efficient technologies operated within water and resource recovery facilities (formerly known as wastewater treatment plants). Rethinking the way we deal with wastewater has become the new challenge and a key tool to implement the Circular Economy Action Plan, to address numerous UN Sustainable Development Goals, as well as to provide support tools to improve resilience to environmental and global threats, including climate change, water and food security, epidemic outbreaks and political instability. To tackle these challenging goals, new technologies as well as multidisciplinary tools are needed to pave the way toward a new water-economy, including: innovative technologies, integrated and risk-based approaches, and adequate regulatory and economic guidelines to promote technological uptake and societal acceptance. In Focus – a book series that showcases the latest accomplishments in water research. Each book focuses on a specialist area with papers from top experts in the field. It aims to be a vehicle for in-depth understanding and inspire further conversations in the sector.

Book Description
The Pennsylvania State University has one of the few research-dedicated ecological wastewater treatment systems (or Eco-MachinesTM) in the United States. An Eco-MachineTM cleans contaminated water by passing it through a series of aquatic tanks typically housed inside a greenhouse. The ecosystem within an Eco-MachineTM consists of bacteria, fungi, algae, plants, snails, and other beneficial organisms, which together feed on waste products and effectively clean the water to the same standards as conventional wastewater treatment plants, but with a smaller energy footprint. Unfortunately, there is no established protocol for starting these systems, and typically it takes as long as 6 months after the introduction of wastewater to achieve efficient treatment. To better understand the requirements of the dominant organisms in the system and thereby minimize start-up times, our research team is analyzing how the microbial community develops throughout the 6-month start-up period of the pilot-scale Eco-MachineTM on campus. During this time, the system experienced changes in water quality, particularly in the following parameters: 1) dissolved oxygen (DO); 2) conductivity; 3) oxidation-reduction potential (ORP); 4) pH; 5) temperature; 6) chemical oxygen demand (COD); and 7) the concentration of dissolved nutrients like carbon, nitrogen, and phosphorous. The COD results confirmed the system's treatment efficacy to that of conventional wastewater treatment standards. Additional water samples were collected, centrifuged, and the resulting pellet preserved at -80 oC for later DNA extraction. Now that the system has reached the desired treatment efficiency, the DNA corresponding to the dates when water quality improved is currently being sequenced and analyzed by graduate students in the laboratory. Hopefully, the combined analysis of the DNA and water samples will yield valuable information about the microbial populations responsible for these improvements and the conditions that optimized their growth. The ultimate goal of this project is to develop a standard protocol for improving the start-up efficiency of ecological wastewater treatment systems, so that they can be more easily applied for improving water quality in developed and developing nations.

Book Description
This is the first of two volumes that together provide a comprehensive overview of the current sustainable and low-cost wastewater treatment technologies applied in communities that lack the financial and technical resources needed for an environmental, disease prevention and health nexus.This book reviews natural wastewater treatment technologies and traces the current challenges in wastewater management and sustainability. Divided into 4 themed parts, the chapters from expert contributors cover topics such as simplified and low-energy natural treatment facilities, bioremediation and biotechnology for green future, environmental impact assessment of wastewater reuse, wastewater management and sustainability for irrigation, high-performance and cost-effective biosorbents for heavy metals removal, and eco-friendly nanomaterials for wastewater environmental management. The readers will discover essential recommendations for improving natural treatment systems to withstand emerging contaminants, namely, endocrine disruption chemicals, surfactants, personal care products, pesticides, and pharmaceuticals. Readers will also find valuable guidelines to ensure sustainable and innovative solutions for wastewater treatment in the light of climate change, resource, demand, and funding challenges.Given the breadth and depth of its coverage, the book offers an invaluable source of information for researchers, students and environmental managers alike.

Book Description
Innovative and Integrated Technologies for the Treatment of Industrial Wastewater deals with advanced technological solutions for the treatment of industrial wastewater such as aerobic granular biomass based systems, advanced oxidation processes integrated with biological treatments, membrane contactors and membrane chemical reactors. Wastewater from pharmaceutical, chemical and food industries as well as landfill leachates are specifically considered as representative of major problems encountered when treating industrial streams. The economic and environmental sustainability of the above solutions are also reported in the book and compared with the alternatives currently available in the market by life cycle assessment (LCA) and life cycle costing (LCC) methodologies. The implementation of the considered solutions at large scale could support and enhance the competitiveness of different industrial sectors, including the water technology sector, in the global market. Innovative and Integrated Technologies for the Treatment of Industrial Wastewater also makes a contribution towards defining: new concepts, processes and technologies in wastewater treatment with potential benefits for the stable quality of effluents, energy and operational costs saving, and the protection of the environment new sets of advanced standards for wastewater treatment new methodologies for the definition of wastewater treatment needs and framework conditions new information supporting development and implementation of water legislation.
