irradiation treating acid red dye wastewater and activated charcoal was used as catalyst. The results showed that the re-moval rate can reach 96%~98% when concentration of acid red dye wastewater is 400mg/L, carbon dosage is 2.0g, microwave power is 800W, irradiation time is 6min. Generally speaking,

Wastewater contains different types of pollutants in varying amount and concentrations. Among these, presence of dyes is of major concern for wastewater treatment. The main aim of this study is to determine equilibrium and kinetic parameters necessary to design a batch adsorber for the adsorption of acid dye 25 by Saudi bentonite clay.

"Sustainable Decolorization of Reactive and Acid Dye ...

Photo-Fenton oxidation is an advanced oxidation process (AOP) used to degrade low-concentration textile ,dye wastewater, using expensive chemicals. The technique has shown promise in laboratory-scale projects, but has not been scaled up sustainably to function for industry. Aerobic biodegradation is a common biological treatment method used in large-scale textile industrial applications that ...

In the present study, Fenton's oxidation of a chromium complex disazo ,dye, (,Acid, Blue 193) synthesis ,wastewater, was evaluated, modeled and optimized by employing Central Composite Design. Within this context, the individual and interactive effects of critical process parameters such as Fe2+, H2O2 concentrations, initial chemical oxygen demand (COD) and reaction time was assessed.

Abstract In this study, ,dye, removal from synthetic colored ,wastewater, using electrocoagulation process was studied. ,Acid, Red 73 was used as model ,dye, compound. The effects of operational parameters, such as current density, reaction time, initial ,dye, concentration, electrolyte concentration, initial pH, and polyaluminum chloride (as a coagulant), on ,dye, removal were investigated.

Whereas in the case of acid dye, the CKD was dissolved entirely, which may be the interaction of dye molecules with the CKD. Similarly, Shaheen et al. ( 137 ) studied the sorption nature of the four divalent metals, i.e. cadmium (Cd), copper (Cu), lead (Pb) and zinc (Zn) in textile wastewater with three different sorbents such as CKD, sawdust and activated C ( 36 ), ( 138 ), ( 139 ).

In this research, sludge of Jalaliyeh ,water treatment plant, in Tehran was used as an alternative coagulant for the removal of a specific type of ,acid dye, (,acid, red 119 (AR119)). For this purpose, the effect of initial pH, coagulant dose and initial ,dye, concentration on ,dye, removal efficiency were investigated. Results showed that the ,dye, removal rates were largely dependent on pH.
