Dissolved Air Flotation in Industrial Wastewater Treatment

Optimizing 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...

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...

Treatment of Milk Industry Effluent by Dissolved Air Flotation

In this work, the application of the flotation technique by dissolved air (FAD) to the treatment of milk industry effluent (milky effluent) is analyzed. Initially, batch studies were carried out in a column built of acrylic with an external diameter of 2.5 cm and 50 cm in height. Afterwards, the performance of a flotation tank with a 5.5 L capacity in the treatment of the milky effluent was add...
