Efficient particle separation in order to meet stringent regulatory standards represent one of the biggest challenges facing the process industry operators today. Emerging environmental problems such as climate change, population growth and natural resource depletion make it more compelling to undertake research into alternative phase separation techniques and optimization of existing ones. Meeting this challenge requires innovative, revolutionary and integrated approach in the design and optimization of various unit processes in fine particle separation. Flocculation is widely used as an effective phase separation technique across many process industries such as water and wastewater treatment and in minerals processing. In this work, a new pre-treatment technique was developed using a patented bench scale reactor unit as a technical proof of concept. Furthermore, the book provides a valuable insight into the hydrodynamics and fluid-particle interactions within the agglomeration units. The relatively high solids content of the stable pellets (approximately 30 %) and very low residual turbidity of the post-sedimentation supernatant (7 NTU) clearly demonstrate the potential of this technique. In addition to significantly improving the subsequent solid-liquid separation efficiency, this study also showed that the effluent can be recycled back into the sewer network or utilized for non-portable reuse. The findings obtained from this research will be extremely useful in the scaling up and optimization of the reactor system.

It was intended to return with the International Gothenburg Symposia every other time to the birthplace of these events, Gothenburg in Sweden. But instead the 8th symposium has been invited to be organized and held in Prague, i. e. in the midst of Central and Eastern Europe a region now keen on intensified environmental control. This attests that the symposia have attained such standing in the interna tional world of operators, designers, officers and researchers in water treatment technology that their presence in various parts of the world has been requested. And this ever growing significance, in short the success of this conference series, stems form the fact that the symposia offer a unique platform for the exchange of ideas and experiences on all aspects of water and wastewater treatment between administrators, engineers and scientists. The content of this book, i. e. the schedule of the symposium lectures, results for the most part from a vast response to an international call for papers. Many excellent contributions are included in this volume but at the same time many outstanding ones could not be included for lack of time and space. The total sum of these contributions document again the development in the field, both in terms of new technological (and other) developments as well as public and administrative acceptance and approval of solutions offered.

With the increased volume of sewage sludge generated as a result of extended sewerage and advanced wastewater treatments, its management is becoming of ever greater concern in both industrialised and emerging countries.During recent years there has been a worldwide movement toward a strategy of reusing and taking advantage of the energy content of residues, in particular of transforming a waste material produced by a treatment works (sludge) into a useful and usable product (biosolid). The selection of a use/disposal method or management system is often based on factors such as local traditions, personal experience, public opinion, etc., with less emphasis on the much more important technical factors, such as local geography, climate, land use, availability of disposal sites and regulatory constraints.Sludge into Biosolids gives up-to-date coverage of sludge treatments and of its use and disposal, focusing on the practical aspects of sludge/biosolids management. Operational variables and sludge properties affecting each management operation are discussed.Sludge into Biosolids provides a comprehensive overview for practitioners, graduates and researchers as well as politicians, decision-makers and public administrators, not only of the different options for using/disposing of sewage sludge and the requirements to be met for each of them, but also of the different methods for processing sewage sludge in order to modify its physical, chemical and biological properties, to meet the requirements for its utilization.ContentsPart I: Sludge Production and CharacterizationPart II:Options for Biosolids Utilization and Sludge Disposal Part III: Treatments and Operations

Investigates strategies for reducing the volume and weight of water treatment plant residuals in preparation for disposal in landfills. The report begins with a six-step protocol for evaluating and improving polymer conditioning before water treatment residuals are dewatered. The research portion examines three online characterization techniques for monitoring and controlling the polymer dose used to condition water treatment residuals before dewatering. The results of laboratory jar tests and plant-scale studies are presented for liquid-stream viscosity, streaming current, and light obscuration techniques borrowed from the wastewater industry.

Potable water treatment processes produce safe drinking water and generate a wide variety of waste products known as residuals, including organic and inorganic compounds in liquid, solid, and gaseous forms. In the current regulatory climate, a complete management program for a water treatment facility should include the development of a plan to remove and dispose of these residuals in a manner that meets the crucial goals of cost effectiveness and regulatory compliance. This comprehensive water treatment residuals management plan should involve the: 1) Characterization of the form, quantity, and quality of the residuals; 2) determination of the appropriate regulatory requirements; 3) identification of feasible disposal options; 4) selection of appropriate residuals processing/treatment technologies; and development of a residuals management strategy that meets both the economic and noneconomic goals established for a water treatment facility. This manual provides general information and insight into each of these activities that a potable water treatment facility should perform in developing a residuals management plan.
