This book was released on 2001-04-30 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dissolved air flotation (DAF) is an increasingly applied technology for particle removal in water and wastewater treatment. In DAF tiny air bubbles attach to the particles, which float to the surface, forming flocs which can be periodically removed to a sludge channel. The technique originated in the early 1900s, but has steadily widened its application across municipal and industrial water and wastewater treatment, earning a reputation for reliability, controllability and effectiveness. The aim of the Helsinki conference was to provide an opportunity for researchers and practitioners to examine and discuss current developments and applications of DAF technology in water and wastewater treatment. From the 58 oral and poster presentations, 26 papers have been selected for these proceedings. The papers have been divided into four themes: drinking water treatment, wastewater treatment, industrial and trade applications, theory and modelling.

This book was released on 2011-10-06 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: The definitive work on Dissolved Air Flotation Systems (DAF) for clarification of drinking water Dissolved Air Flotation for Water Clarification is a complete design and application source for the water industry divided into three parts: The first develops a fundamental basis for understanding how the process works, and might be adapted to work better. The second provides a reference for design engineers, water operators, and water managers regarding applications where DAF might be incorporated in an overall treatment scheme. The third develops the necessary DAF design concepts and to illustrate them by description of practical applications. Using DAF to remove particles is not only an important process for conventional drinking water plants, but may also be used as a pre-treatment process in membrane plants including reverse osmosis for water desalinization, and in water reuse applications. Dissolved Air Flotation for Water Clarification offers: Information on new applications of DAF in advanced water treatment, desalinization, water reuse, and industrial treatment in food, waste, and pulp and paper Detailed examples, including the world’s largest new DAF plant ever built – Croton, NY water treatment plant A single volume entirely devoted to DAF for drinking water clarification Coverage of conventional and pre-treatment processes SI and conventional units throughout

This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The dissolved air flotation (DAF) has been used in drinking water treatment for its excellent algae and natural organic matter (NOM) removal. DAF drinking water treatability test are often conducted in a DAF jar test apparatus. Although, DAF jar test studies showed that they were able to predict NOM removals at full-scale facilities well, they have not always been successful in predicting the turbidity removals. One possible reason of the DAF jar test inaccuracy results could be associated to the small jar diameter, which may create wall effects. Therefore, the first two objectives of this research are: a) to develop and test a new, larger diameter and larger volume batch bench-scale dissolved air flotation system (LB-DAF) to better simulate turbidity removals in drinking water applications; b) to confirm these results by comparing the LB-DAF and full-scale DAF turbidity removals for two other source waters. The raw water characteristics of the three plants were quite different and the testing was performed at different times of the year. The development/optimization of the LB-DAF evaluated the impact of different variables (i.e., mixing intensity, water depth/tank diameter ratio, impeller shape, saturator pressure and recycle ratio). The results showed that the LB-DAF predicted well the full-scale DAF turbidity removals at three water treatment plants, and these predictions were better than those of DAF jar tests. For the LB-DAF design and operational variables evaluated had a limited impact on the turbidity removals. The LB-DAF predicted well DAF full-scale turbidity removals regardless of water temperature. This is an indication of the robustness of the DAF system. Ballasted sedimentation (BS) is a compact coagulation/flocculation and sedimentation process combination that has become very popular because it is very compact and because it can handle large variations in raw water turbidity and NOM. The literature survey did not initially identify studies on the BS treatment of algal impacted waters, for which DAF is considered particularly suitable. Thus, the third main objective of this dissertation was to compare the efficiency of BS with that conventional gravity settling (CGS), and that of DAF for the treatment of an algal impacted water via jar tests. These comparisons were performed at the Belleville Water Treatment Plant using Bay of Quinte water, one of the most eutrophic zones of Lake Ontario. Unfortunately, a change of weather prior to the testing resulted in raw water samples with relatively low concentrations of algae and cyanobacteria. The testing showed that DAF and BS had very similar NOM, cyanobacteria/algae (chlorophyll a and phycocyanin) removals.; however, the BS required microsand addition, polymer addition and a slightly higher alum dose. Only for turbidity removal the DAF was somewhat superior. It is suggested that these comparison experiments be repeated with waters that are more impacted by algae and cyanobacteria.

This book was released on 2012 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT CONT'D: Charge analysis parameters zeta potential and streaming current were found to have a strong correlation in bench-scale testing, though the relationship between the two was affected by the coagulation pH. The results suggest that utilizing streaming current for coagulant dose control at a full-scale WTP would be best accomplished by establishing a consistent relationship between raw water quality, pH and other factors with streaming current experimentally before relying streaming current targets for dose control. Equivalent or improved DAF efficacy for solid-liquid separation was found when the recycle rate was lowered from 12 to 6 % in bench-scale tests and 12 to 8% in full-scale tests. The results suggested that maintaining an optimum air:solids ratio improved treatment performance, possibly by providing adequate bubble contact opportunities while minimizing excess shearing of the sludge blanket. The most significant finding of this research was that maintaining the coagulation pH in WTPs utilizing PACl coagulants is of utmost importance during source water quality deterioration in order to optimize treatment performance as well as prevent excess dissolved and precipitated aluminum from entering a public drinking water supply.
