Textile Wastewater Treatment on a Spinning Disc Reactor: Characteristics, Performances, and Empirical Modeling

Sequencing batch biofilter granular reactor for textile wastewater treatment.

Textile wastewater is difficult to treat as it usually contains considerable amounts of different pollutants, which are often recalcitrant, toxic and inhibitory. Therefore, complex treatment schemes based on the sequence of various steps are usually required for an effective treatment. This explains why textile effluents are often treated in centralized plants and sometimes mixed with municipal...

Electrocoagulation process for textile wastewater treatment in continuous upflow reactor

This study investigates the influence of operating parameters (current density, detention time and time of electrolysis) on COD and color removals from a simulated basic dyebath effluent using electrocoagulation (EC) with iron electrodes in continuous flow mode. Till today, researchers are mainly focused on use of EC systems in batch processes. Looking to large quantities of wastewater from tex...

Textile Dyeing Wastewater Treatment

Textile industry can be classified into three categories viz., cotton, woolen, and synthetic fibers depending upon the used raw materials. The cotton textile industry is one of the oldest industries in China. The textile dyeing industry consumes large quantities of water and produces large volumes of wastewater from different steps in the dyeing and finishing processes. Wastewater from printing...

Micromixing in a Rotor–Stator Spinning Disc Reactor

This paper presents the micromixing times in a rotor-stator spinning disc reactor. Segregation indices are obtained at different rotational speeds performing the Villermaux-Dushman parallel-competitive reaction scheme. Consequently, the corresponding micromixing times are calculated using the engulfment model, while considering the self-engulfment effect. It was found that the segregation index...
