Removal of Congo red from textile wastewater by ozonation
Congo red, which has a complex molecular structure with various diazo aromatic groups, is widely used in textile industry as an anionic dye. The purpose of this study was to investigate the degradation of Congo red in laboratory solution which had the chemical properties of the rinse waters of textile manufacturing dye-houses and the samples with Congo red alone wastewater by ozonation and to o...
متن کاملRemoval of the 2-Mercaptobenotiazole from Model Wastewater by Ozonation
The feasibility of ozonation process for 2-mercaptobenzothiazole (2-MBT) removal follows from results of ozonation of the model wastewater. Total removal of 2-MBT was observed after 20 minutes of ozonation. Very good reproducibility of repeated ozonation trials including sampling and analysis was observed. However, the majority of dissolved organic carbon (DOC) and chemical oxygen demand (COD) ...
متن کاملGenotoxicity removal of reclaimed water during ozonation.
Genotoxicity in wastewater and reclaimed water now is gaining increased attention because of genotoxins' potential damage to the ecosystem and human health. The effect of ozonation on genotoxicity in reclaimed water was investigated. It was found that ozonation decreased the genotoxicy dramatically in three tertiary treatment plants. In the further batch ozonation experiment in laboratory, seco...
متن کاملEnhanced bio-recalcitrant organics removal by combined adsorption and ozonation.
Removal of bio-recalcitrant and toxic compounds from wastewaters has been a major objective of industrial manufacturers for a few years. Due to the potential risk toward public health, regulations are becoming increasingly strict and classical treatments like biological treatments are not efficient. Other techniques such as incineration, oxidation or adsorption provide higher levels of removal ...
متن کاملDegradation of Benzothiazole by Ozonation and Adsorptive Ozonation
Benzothiazole derivatives are widely used as industrial chemicals; mainly as fungicides in the leather and wood processing industries, herbicides, components in automobile antifreeze, corrosion inhibitor in cooling systems, and in particular as vulcanization accelerators in the rubber industry1. Benzothiazole enters the environment from a variety of sources such as the leaching of rubber produc...
