Introduction: Textile wastewaters from dyeing and finishing processes are heavily polluted with dyes, textile auxiliaries and chemicals and have a broad range of pH, high COD concentration and suspended particles. In this study, the efficiency of color and turbidity removal from synthetic textile wastewater samples were investigated by combined process of coagulation/ flocculation and electron ...

Due to the pollution of dyeing and textile industry wastewaters in different colors and the need to remove these pollutants from the wastewaters, it is necessary to study and develop effective and efficient technology solutions required. To remove dye from aqueous solutions, photodegradation is employed as an effectively simple way. Thus, the BiOBr photocatalyst was chemically made by synthesis...

The pharmaceutical production industries generate wastewaters that should be properly treated because in some cases they are highly toxic. For this reason the safe inactivation before disposing them into the environment must be guarantee. This paper deals with an ozone treatment system for the wastewaters generated in the cytostatic production. The cytostatics present in the wastewaters treatme...

Introduction: The dye wastewaters of textile industries are often toxic and persistent in the environment. In previous years, various methods are considerate in the removal of reactive dyes. Reactive red 198 dye is one of the mono azo dyes that is now used in textile industries. The aim of this study was to investigate the efficiency of Russian Knapweed Flower powder in the removal of reactive ...

Background & Aim: Industrial wastewater is one of the most important sources of hazardous pollutant emissions. Having high levels of various dyes, textile wastewater is considered as one of the major environmental pollutants. The aim of this study was to compare the efficiency of almond shell ash as a natural absorbent in comparison to commercial activated carbon in removing basic red 18 dye fr...

Wastewater discharge from textile industries concern environmental risks. Superiority of microbial methods over other high cost combined includes conversion persistent organic materials to non-toxic last materials, sustainability, low cost, and comfortable. Textile wastewaters can have opposite effects on the quality water in total carbon (TOC) Chemical oxygen demand (COD). Agitation cultures r...

Treatment of textile wastewater with domestic as co-substrate was investigated in this study. Combined and at different mixing ratios (100:0, 80:20, 60:40) treated under anaerobic reactor. The influence residence time, fraction initial pH were determined view COD color removal. Response Surface methodology (RSM) Box–Behnken design (BBD) employed to determine conditions for higher simultaneous r...

Introduction: Dyes are among the most hazardous chemicals in industrial wastes due to their toxicity for aquaculture, reduction of light permeability, and in turn development of disorders in photosynthesis process. The current study aimed to investigate the efficiency of coral in removing red reactive 198 from textile dye wastewater was investigated. Materials & Methods: In this experimental st...
