Reclamation of Effluent Textile Wastewater Using Micro/nano Bubbles-Dissolved Ozone Flotation Process

Colour Removal Technology Using Ozone in Textile Industrial Wastewater Effluent: an Overview

The elimination of pollutants from waste water is a serious challenge that needs to be addressed. The conventional treatment process has limitation of not completely removing colour from wastewater. Oxidation with ozone proves to be one of the most efficient methods of treatment of colored aqueous effluent from textile industries. The study highlights the importance of ozone in colour removal t...

Dissolved Air Flotation in Industrial Wastewater Treatment

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...

Textile Wastewater Treatment by Electrocoagulation Process using Aluminum Electrodes

Background and purpose: Textile industries are among the most polluting industries regarding the volume and the complexity of treatment of its effluents discharge. This study investigated the efficiency of electrocoagulation process using aluminum electrodes in basic red 18 dye removal from aqueous solutions. Materials and Methods: This study was performed in a bipolar batch reactor with ...

A dispersed-ozone flotation (DOF) separator for tertiary wastewater treatment.

A dispersed-ozone flotation (DOF) separator was devised for a pilot study of tertiary wastewater treatment for re-use purposes. As a compact device combining coagulation, ozonation and flotation in an integrated unit, the DOF separator achieved a very high removal of SS, TOC, UV254 and colour, as well as effective inactivation of coliform and total bacteria within a short hydraulic retention ti...
