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in the technology have expanded the range of applications for DAF; however, engineers and designers frequently use outdated and insufficient design data to design and specify DAF systems for industrial pretreatment.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...

Comparison of Dissolved Air Flotation Process for Aniline and Penicillin G Removal From Aqueous Solutions

Introduction: The presence of antibiotics due to toxicity and sustainability as well as organic compounds as a combination of hard biodegradable wastewater is an undesirable issue in many industries. The aim of this study was to evaluate the efficiency of dissolved air flotation process for aniline and penicillin G removal from aqueous solutions. Methods: This was an empirical-lab study to w...

Comparison of Centrifugation, Dissolved Air Flotation and Drum Filtration Techniques for Harvesting Sewage-grown Algae

Three different techniques of harvesting microalgae from four pilot scale (125 m 2) and two demonstration ponds (1200 m 2) have been investigated. The processes included centrifugation, chemical flocculation followed by flotation and continuous filtration with a fine-weave belt filter. None of these processes was completely satisfactory. Centrifugation gave good recovery and a thickened slurry,...
