Handbook on Particle Separation Processes
Author: Arjen van Nieuwenhuijzen
Publisher: IWA Publishing
ISBN: 1843392771
Category : Science
Languages : en
Pages : 241
Book Description
Particles in water play an important role in all kinds of water quality and treatment issues. Since the early beginnings of centralised water production and treatment, the main goal of water purification was primarily the removal of water turbidity in order to produce clear water free from visible particles. The Handbook on Particle Separation Processes provides knowledge and expertise from a selected group of international experts with a wealth of experience in the field of particles and particle separation in water and wastewater treatment. The Handbook on Particle Separation Processes includes an edited selection of presentations and workshops held at the academic summer school Particle Separation in Water and Wastewater Treatment, organised under the supervision of the IWA Specialist Group Particle Separation.

Guidance Manual for Coagulant Changeover
Author: James DeWolfe
Publisher: American Water Works Association
ISBN: 9781583212899
Category : Science
Languages : en
Pages : 210
Book Description
This manual is a source document for utilities that are considering a coagulant changeover. It is intended to provide an appreciation of what must be considered for a successful changeover based on the input of U.S. and Canadian utilities (Chapters 1 and 6). New regulatory requirements will likely have the broadest and most substantial impact on primary coagulant use (Chapter 3). The Interim Enhanced Surface Water Treatment Rule (IESWTR) and Stage 1 Disinfectant and Disinfection Byproducts Rule (Stage 1 DBPR) will make finished water requirements more stringent to address microbial removal and the impacts of disinfection. Enhanced Coagulation and/or other operational and treatment practices will be used to achieve these requirements. The science of coagulation (Chapter 4) requires a special focus to address the intricacies of coagulation chemistry. The manual provides a step-by-step methodology to conduct a coagulant changeover using a detailed protocol (Chapter 5) -- background, executive summary.

Optimization of Micro Processes in Fine Particle Agglomeration by Pelleting Flocculation
Author: Benjamin Oyegbile
Publisher: CRC Press
ISBN: 1317371461
Category : Science
Languages : en
Pages : 134
Book Description
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.
