Rethinking Dissolved Air Flotation (daf) Design for Industrial Pretreatment
Dissolved air flotation (DAF) has been used with increasing frequency in recent decades for the treatment of industrial wastewater. Advances in the technology have expanded the range of applications for DAF; however, engineers and designers frequently use outdated and insufficient design data to design and specify DAF systems for industrial pretreatment. Discussions of advances in DAF design ar...
متن کاملeffect of dissolved air flotation process on thickening of activated sludge
aims: sludge is an inescapable component of all wastewaters that originated from their treatment. dissolved air flotation (daf) process as an alternative clarifier is used in treatment of drinking water, pretreatment of wastewater, and as a phase separator in sludge activation processes. this study aimed to calibrated the usage of daf process in a laboratory scale and under various conditions, ...
متن کاملOptimizing Dissolved Air Flotation Design System
Dissolved Air (Pressure) Flotation-DAF, is a well-established separation process that employs micro-bubbles as a carrier phase. This work shows results concerning bubble generation at low working pressures in modified DAF-units to improve the collection of fragile coagula by bubbles. DAF of Fe (OH)3 (as model) was studied as a function of saturation pressure in the absence and presence of surfa...
متن کاملeffect of dissolved air flotation process on recycling activated sludge thickening of wastewater treatment plant of kashan's shahid beheshti hospital
aims: intensification of current environmental legislation leads to an increase wastewater treatment sludge volume. so reducing the sludge volume is considered as a strategy to improve and solve the problems of secondary pollution of sludge. dissolved air flotation (daf) as a substitute clarifier is used for separation of activated sludge liquid-solid phases. the aim of this study was to estima...
