Modeling the fate of chemical constituents such as cations and anions, organic and inorganic ligands, etc., is essential to understand the long-term utility of groundwater for various purposes. The chemical modeling helps to describe the chemical characteristic of an aqueous system to solve a simultaneous set of equations, which explains the equilibrium reactions and mass balance on dissolved element for the output consists of theoretical distribution of aqueous species for dissolved elements....

Investing in Water and Growth: Recent Developments and Perspectives addresses this conundrum in a cohesive and practical way. It is a one-stop shop for understanding why the financing of water-related expenditures matters, what is at stake, and the options available to ensure water-related investment needs are properly financed in ways that generate benefits for communities and contribute to sustainable growth. The book combines the perspectives of policymakers, economists and financiers in a un...

This book gives an interdisciplinary overview on urban ecology. Basic understanding of urban nature development and its social reception are discussed for the European Metropolitan Area of Berlin. Furthermore, we investigate specific consequences for the environment, nature and the quality of life for city dwellers due to profound changes such as climate change and the demographic and economic developments associated with the phenomena of shrinking cities. Actual problems of urban ecology shoul...

This book presents a Two-Stage Anaerobic Digestion (TSAD) technique for producing hydrogen and methane, following a step-by-step approach in order to guide readers through the experimental verification of the related hypothesis. In the first stage of AD, the reaction conditions are optimized to obtain the maximum amount of hydrogen, while in the second the liquid residue from the first phase is used as a substrate to produce fuel-methane. AD has traditionally been used to reduce the organic cont...

The term 'Agro-Industries' covers a range of significant industrial activities based on the practice of agriculture or the processing of its products. Major industries such as textiles and dyestuffs, pulp and paper, leather, food-processing, the refining of edible oils and sugar, etc. fall into this category. These proceedings, the fourth from a conference series that continues to grow in scale and importance, comprise 48 papers, selected from over a hundred presented, on the following aspects...

Anaerobic digestion processes for the treatment of wastewaters and sludges are well over 100 years old. The anaerobic process is a natural gasification process, producing very useful end-products. It has taken a long time to prove that these processes are useful tools in sustainable development. A breakthrough was the development of the Upflow Anaerobic Sludge Bed reactor by Professor Gatze Lettinga. This showed that the anaerobic process could be operated as a highly effective and high-rate wa...

The objective of this research was to assess and document state-of-the-art of wastewater treatment plant sensing and control systems to discover successful practices that can be replicated by other facilities interested in automating. The research was based on the literature, the experience of the project and advisory teams, and onsite surveys. The project focused on the best examples of applied sensors, control strategies, and computerized process control in wastewater treatment plants....

A complete guide to OSHA training requirements for hazardous waste cleanup professionals Love Canal, Times Beach, Bhopal--these and other industry-related environmental disasters provided the impetus for present-day regulations governing cleanup of hazardous waste sites and the health and safety training of workers engaged in these operations. This manual addresses the 1986 amendments to Congress's "Superfund" act (known as SARA) and the growth industry in hazardous waste remediation that emerge...

Selection, installation, and maintenance of fiberglass pipe in potable water systems.

Das Buch bietet in einem ersten Hauptteil eine Einfuhrung in Stroemungsvorgange in der gesattigten und ungesattigten Zone und deren analytische Beschreibung. Im Anschluss wird erlautert, wie man unterirdische Stroemungen auf dem Computer numerisch modellieren kann. In einem zweiten Hauptteil werden Prozesse der Stoff- und Warmeausbreitung behandelt. Dabei erfolgt eine analytische Beschreibung von Transport-, Sorptions-, Abbau- und Produktionsvorgangen sowie die darauf aufbauende Umsetzung in num...

This new volume addresses the global water crisis by presenting new ways to use irrigation water judiciously through innovative fertigation management. It looks at the research and review work done throughout the world on micro irrigation and the techno-economic feasibility of various fertigation irrigation water management systems. Taking a multidisciplinary perspective, the chapters look atusing fertigation to increase the effectiveness of irrigation systemscrop performance evaluation of vari...

A new category of contaminants is capturing the attention of citizens, scientists, and regulators. Anthropogenic chemicals occur in air, soil, water, food, and in human and animal tissues. This report considers specific pollutants such as pharmaceuticals, personal care products, antimicrobials and antibiotics, hormones, plasticizers, surfactants, fire retardants, pesticides, and nanoparticles. It is a must-have for undergraduate and graduate students in environmental engineering and resources; t...

Roland W. Scholz' Die letzte Dekade des 20. Iahrhunderts war durch einige Besonderheiten und Er- eignisse gekennzeichnet, die bemerkenswerte Veranderungen der Umweltbe- lastungen und ein neues Denken bezogen auf die Beurteilung von UmweltmaB- nahmen zur Folge hatten. Zu ihnen gehoren neben dem Abschluss des Industrie- zeitalters, mit der eine weitgehende Reduktion von Emissionen im Bereich Pro- duktion einherging, sowie dem Phanomen der Globalisierung und vor allem der Trend zur Monetarisierung...
