Until now, techniques for studying biofilms- the cellular colonies that live in drinking water systems, wastewater operations, even ground and surface water- have been limited. Yet during the last decade, biofilms have become a critical element in water quality preservation systems, a key component of wastewater treatment biological reactions and the subject of extensive microbiological inquiry. An understanding of biofilm development, structure and dynamics is one condition for improving water supplies and for addressing technical problems such as biofouling, corrosion and bioweathering. Biofilms: Investigative Methods and Applications provides the first in-depth assessment of current and experimental ways to study biofilms, both in sample form and in situ. It shows how sensors, microscopy, lasers, and calorimetry, among other tools, can be used to obtain data on the morphology and metabolism of biofilms. This text is the first to organize and examine the best methods for investigating biofilms. It covers culture-based methods and emerging nondestructive techniques. It also shows how they can be used to characterize biofilms in a variety of manmade settings, such as sewers, wastewater plants, and drinking water distribution systems, as well as in karsts and groundwater sources. In clarifying the way biofilms are studied, the book offers new insights into these living films. It also applies inquiry techniques to the many problems confronting the environmental specialist-corrosion control, biofouling, and the improvement of fixed reactors in wastewater treatment. At the same time it explains technologies for the controlled growth of biofilms and shows how biofilms can be effectively monitored and subjected to quantitative analysis. The technical information in Biofilms: Investigative Methods and Applications is designed to be of use to engineers and researchers and to be helpful in the generation of electronic data.
These three volumes (Golden Nuggets) present the latest knowledge in the science and technology of mineral processing and new industry applications, related to the following topics: mineral and material characterization and liberation, comminution, classification and agglomeration, hydro and biohydrometallurgy, physical separation processing, flotation, and process simulation and control. Due to the increasing application of mineral processing techniques in waste treatment, recycling and soil remediation have received special attention.The three volumes present a selected collection of peer-reviewed papers devoted both to the theory of mineral processing (Volumes A and B) and to process design and plant application (Volume C).
Mineral processing technologies have been used for decades to protect the environment and many examples of such applications are given here. The book covers four major subject areas: fundamentals; environmental pollution and its prevention; separation processes; and innovative techniques. Audience: Scientists, engineers and technologists conducting both applied and basic research into the different environmental aspects of mineral processing.
Mechanochemistry as a branch of solid state chemistry enquires into processes which proceed in solids due to the application of mechanical energy. This provides a thorough, up to date overview of mechanochemistry of solids and minerals. Applications of mechanochemistry in nanoscience with special impact on nanogeoscience are described. Selected advanced identification methods, most frequently applied in nanoscience, are described as well as the advantage of mechanochemical approach in minerals engineering. Examples of industrial applications are given. Mechanochemical technology is being applied in many industrial fields: powder metallurgy (synthesis of nanometals, alloys and nanocompounds), building industry (activation of cements), chemical industry (solid waste treatment, catalyst synthesis, coal ashes utilization), minerals engineering (ore enrichment, enhancement of processes of extractive metallurgy), agriculture industry (solubility increase of fertilizers), and pharmaceutical industry (improvement of solubility and bioavailability of drugs). This reference serves as an introduction to newcomers to mechanochemistry, and encourages more experienced researchers to broaden their knowledge and discover novel applications in the field.
