Endocrine Disrupting Chemicals (EDCs) have been shown to produce changes in the endocrine system of organisms that lead to increases in cancers and abnormalities in reproductive structure and function. Recent research has highlighted the existence of hormonally active compounds in sewage and industrial effluents and their potential for recycling back into the environment - including drinking water supplies- through point sources and non-point sources. Endocrine Disrupters in Wastewater and Sludge Treatment Processes presents the latest research on EDCs, covering the sources, fate, and transport of EDCs in sewage and industrial effluents, and sludge treatment and disposal options in light of effects on receiving environments. In addition, the authors review current legislation, future research needs, and potential management strategies for endocrine disrupters in the environment.

The removal of endocrine disrupting compounds (EDCs) from municipal wastewater by conventional and advanced wastewater treatment methods was investigated. Effluent from a membrane bioreactor (MBR), on average, contained lower EDC concentrations than a conventional (activated sludge) treatment plant receiving the same influent wastewater. MBR effluent was also disinfected to meet California State Guidelines (Title 22) for water reuse using chlorine, chloramines, chlorine dioxide and UV. Disinfection was not shown to impact EDC concentrations except for Bisphenol A (95% removal). MBR effluent was also treated using a bench-scale RO membrane system. The RO reduced all EDCs monitored, except BPA, to non-detectable levels (

The presence of endocrine disrupting compounds (EDCs) and pharmaceutically active compounds (PhAC) such as pesticides, personal care products, antibiotics and pharmaceutical compounds, in sewage, industrial, and domestic waters has extensively become the major concern for health and environmental organizations. These compounds have the ability to interact with mammalian endocrine system and disrupting their functions. The traditional activated sludge processes are designed to degrade solids, organic carbon and nitrogen loading. Although several treatment steps in a wastewater treatment plant can contribute to partial removal of EDCs, effective removal has been a challenge due to their resistant chemical and biological degradation and extreme low concentrations. Membrane bioreactor (MBR) used in this study is novella better water reclamation technology that shows several advantages including stable operation conditions due to long solid retention time (SRT); concentrated mixed liquor suspended solids (MLSS); and low F/M ration in comparison with conventional wastewater treatment. This research will utilize these advanced membrane technologies to develop wastewater treatment processes for removal of EDCs in order to recover and reuse wastewater to augment drinking water supplies. A set of model EDCs including acetaminophen, amoxicillin, atrazine, estrone, and triclosan were selected to study the removal by membrane bioreactor. Those compounds were chosen based on their concentrations present in Oklahoma and Arkansas wastewater and to represent each group of compounds. Optimized HPLC method was used for detection of these model compounds. A Lab-scale MBR operated with real wastewater was tested under different operating conditions, such as retention time and volatile suspended solids concentrations to remove the spiked EDCs. The module MBR can reach desired chemical oxygen demand COD (

Technical information for using activated sludge to treat effluents from multiple industries Covers virtually all traditional and advanced methods, as well as treatability and process modeling New methods for removing U.S. and European regulated microconstituents, trace organics, active pharmaceutical ingredients and other contaminants Explains advances in water reuse and plant retrofitting Useful for in-house training This comprehensive book presents critical information on the applications of activated sludge for treating industrial wastewaters, as well as other effluents that impact POTWs. The book offers details on how advances in activated sludge can be deployed to meet more stringent discharge limits by explaining many novel variations of activated sludge and offering technical guidance on process modeling and optimization. Special attention is given to emerging contaminants and water reuse strategies. Case studies are drawn from the pharma, food and shale gas industries. Based on short courses taught by the authors, as well as hundreds of hours of in-plant consulting, this book offers the tools to understand and modify the activated sludge process for superior and sustainable wastewater treatment. From the Authors' Preface: "After speaking with practitioners, operators and engineers, the authors felt a new text was needed...to cover the following developments: "the continued evolution of the activated sludge process and its numerous designs, configurations and technology developments; "design of industrial water reuse systems...to achieve industry sustainability goals; "changes...from BOD, TSS and nutrient removal to removal of specific organics, toxicity...microconstituents, and more stringent effluent permit limits; "advances in process modeling tools that can be used in combination with treatability testing tools for plant design, optimization and troubleshooting; "concerns over industrial wastewater discharge impacts to POTWs, such as nitrification inhibition, the impact of frac water...and the fate of microconstituents through POTWs."

Wastewater treatment plants usually generate millions of tons of sewage sludge every year. Sewage sludge results from the accumulation of solids from chemical coagulation, flocculation and sedimentation during wastewater treatment. Worldwide, sludge production is steadily increasing, driven by the increasing percentage of households connected to central treatment plants, the increasing tightening of pollution limits on the effluent discharged, as well as the availability of technologies capable of achieving higher efficiency of wastewater treatment. Sewage sludge contains undesirable hazardous substances such as trace elements, pesticides and endocrine disruptors, pathogens and other microbiological pollutants. Therefore, sludge has to be properly treated and disposed of to prevent environmental contamination and health risk. Sludge processing is intended to improve dewatering characteristics, eliminate disease-causing bacteria, reduce smell and decrease the quantity of organic solids. In this way, the end product can be treated further or disposed of with less handling problems and environmental consequences. This new important book gathers the latest research from around the globe on this issue.

In order to analyse the challenges posed by the quest for sustainability, Green Technologies for Wastewater treatment: Energy Recovery and Emerging Compounds Removal evaluates water management together with energy use. The strong effects that the release of emerging pollutants such as endocrine disruptors (EDCs), pharmaceuticals and personal care products (PPCPs) have in wastewater reuse applications are examined, as well as the need to optimize the energy consumption in wastewater treatment. More specifically, this volume focuses on: - Presenting the advantages linked to the application of chemically assisted primary sedimentation (CAPS) that enables energy optimization of wastewater treatment plants and points to the possibility of wastewater as a possible resource; - Discussing the analytical problems related to the analytical detection of emerging pollutants and of their transformation products; - Comparing the efficiency of MBR plants for removing trace pollutants with conventional systems; - Evaluating the application of Wet Oxidation (WO) for the treatment of aqueous effluents to remove trace pollutants; - Reviewing the application of Photo-Fenton process and complementary treatment systems (H2O2/UV-C and Fenton’s reagent) for the degradation of two industrial pollutant categories with significant endocrine disrupting properties: alkyl phenols (nonyl and octyl phenols) and bisphenol A. Green Technologies for Wastewater treatment: Energy Recovery and Emerging Compounds Removal will be of great interest to students, technicians, and academics alike who are interested in evaluating and selecting the technologies that lead to better and more sustainable treatment of these huge classes of pollutants.
