Scaled-Up Biodiesel Production from Meat Processing Dissolved Air Flotation Sludge: A Simulation Study

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...

effect 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, ...

A Comparative Study of Biodiesel Production from Beef Bone Marrow

This study is concerned with the viability of producing biodiesel from waste beef bone fat and evaluate this product according to the quality requirements defined by ASTM D- 6751. Accordingly, beef bone fat was heated to remove the moisture under vacuum at 60 . Alkaline Catalysed Transesterfication was carried out by  using 6:1 molar ratio of ethanol to fat in the presence of 1% w/w sodium hydr...
