The search for efficient and sustainable wastewater treatment technologies is a subject of continuing research. This is due to the emergence of new classes of water contaminants that are recalcitrant to the conventional wastewater treatment technologies and the stringent allowable limits for contaminant levels set by environmental management authorities. The chapter discusses the developments in synthesis methods and application of polymer-metal oxides as emerging facile materials for wastewater treatment. The varying uses of polymer-metal oxides for different processes in water treatment under varying operational conditions and their performance for different pollutants are critically analyzed. Their strengths and inherent limitations are also highlighted. The chapter demonstrates that polymer-metal oxides are facile low-cost and efficient materials and can be integrated in wastewater and drinking water treatment systems.

Sustainable Wastewater Treatment

In the context of global sustainable development, traditional wastewater treatment models reveal its shortcomings due to lack of recovering resource and energy in wastewater. Sustainable wastewater treatment technologies, taken wastewater as carriers of resource and energy, have been paid close attention. Starting from the existing problems of present wastewater treatment technology and focusing on the concept of resource recovery and energy utilization, this paper discussed the production technologies for hydrogen, electricity, diesel and methane from wastewater based on carbon resource recovery, and nitrogen resource treatment technologies with low energy consumption (such as shortcut nitrification-denitrification, ANAMMOX and SND). The latest research processes were also summarized. The research and development orientation of sustainable treatment technology for urban wastewater was put forward.

Sustainable Wastewater Treatment

Background: Industrialization plays an important role in the growth of a nation. But it is also one of the causes for the deteriorating condition of our ecosystem. The pollution, be it aquatic, terrestrial or air -borne, has affected our environment drastically and industrial and domestic wastewater plays a major role in it. As the Earth transforms into an urban sprawl, industries flourish, pollution increases and the natural resources deplete. Recently nano-engineering based technologies have been explored for the purpose of wastewater treatment which help in the detection and remediation of the pollutants present in wastewater. Various nano-material based technologies deployed in wastewater treatment are discussed in this article. Methods: A thorough survey of literature was effectuated, and study was focused mainly upon the different types of nano-materials applied for the purpose of wastewater management and the diverse treatment methods related to them. Literature were also studied to confirm the functionalization of nano-materials as pollution sensors. Results: There are four main kinds of nano-materials employed for the purpose of wastewater remediation i.e. metallic nano-materials, carbon based nano-materials, nanocomposites and dendrimers. The treatment technologies utilizing these materials are nanofiltration, nano-adsorption, nano-photocatalysis and disinfection. Conclusion: Nano-materials are quite efficient in removing the pollutants from different kinds of wastewater. But drawbacks such as expenditure and effect of the materials in the environment make it difficult for real-time utilization. Since the nano-scaled elements behave differently than their standard sized counterparts, the consequence of these materials in human life cycle is unknown. This knowledge gap should be filled so that these materials can be adopted worldwide.

Sustainable Wastewater Treatment

Abstract To reduce demand and discharge, instead of industrial wastewater being poorly treated and disposed of, it can be recycled, reused, or recovered if it is properly managed, thus having a substantial decrease in the water requirement and environmental impacts. The challenge is to select the appropriate process or combination of processes to achieve this based on the wastewater quality. Consequently, the objective of this investigation is to review every technology from conventional through advanced, for reliable and sustainable wastewater treatment and derived sludges, focusing on advantages, disadvantages, and technical gaps for development. Even though there is a wide range of possible technologies, it was evinced that there is huge potential to exploit and make them economically and sustainably viable for waste processing and circular economy, even in the mature massively implemented wastewater treatment technologies in the industry. Overall, we identify that independently from the technology to be studied, the future investigations on every unit, especially on those not vastly implemented, should be focused on: (1) The capacity in removing selected pollutants and decreasing impurities, (2) energy efficiency, (3) environmental safety, (4) economic viability, (5) hybrid processes, and (6) sustainability by waste processing.

Problems related to wastewater reclamation and reuse in the countries of the Mediterranean region are discussed with reference to growing conflicts among agriculture, tourism, cities and industries. All reuse options are strongly influenced by requested water quality, especially the microbiological one, and for this reason standards for reclaimed water have to be fixed having in mind both the safety of reuse and its practical and economical feasibility. The paper will discuss, as an example of a type of approach, also the regulations' evolution with reference to the Italian situation. Some considerations on the feasibility of current indicator bacteria will be done, making reference also to the bacterial re-growth potential associated with various disinfection agents and to the applicability of advanced methods capable to individuate partially damaged cells and therefore useful to a better evaluation of the possible re-growth phenomena.
