aims: several methods have been used for textile wastewater treatment. the aim of this study was to evaluate the efficiency of rosa damascena watering waste ash for cod and color removal from textile wastewater.  materials & methods: rose watering waste was gathered from one of the kashan processing plants. the raw wastewater sample was taken from one of the textile industries in kashan country...

degradation of acrylic water base color from synthetic wastewater by the fenton process was performed. experiments were conducted on the sample containing 100 and 400 mg/l of acrylic water base color. the study was performed for searching optimum values of feso4 and h2o2 concentration, ph and temperature. the h2o2 requirement seems to be related to initial cod of the sample. feso4/ h2o2 ratios ...

This paper presents the treatment of Acid green V by an electrochemical oxidation using Ti/RuO2 IrO2 TiO2 as anode and cathode and NaCl as supporting electrolyte in a tubular flow reactor under continuous single pass process. During the electrolysis, COD reduction, color removal, and energy consumption were investigated under different flow rates and current densities. The experimental results ...

This study was carried out to assess the efficiency of a combined system consisting of up-flow anaerobic sludge blanket (UASB) reactor and down-flow hanging sponge (DHS) system for color removal from reactive dyes wastewater. The UASB reactor and DHS system were operated at HRT of 6 and 2.0 h., respectively. The results obtained indicated that, the combined system was quite effective for remova...

ozonation was carried out for decolorization and coD removal of raw and anaerobically treated uAsb (upflow anaerobic sludge blanket) combined industrial (mainly textile) effluent in a lab-scale bubble column reactor. ozonation of anaerobic bioprocess effluent at a dose of 300 mg/h for 10 min resulted in 81% color and 75% coD removal (100 mgo3/80 mg coD) while for raw wastewater 25 min ozonation...

aims: textile industries are among the manufactures which produce the highly polluted waste water. the purpose of this research was to evaluate the effect of vermifiltration on cod and color removal from textile waste water. materials & methods: this experimental research was performed march to august 2014 in one of the textile factories of kashan region, iran. the glass cubic kits with- withou...

A photocatalytic reactor with UV/TiO2 was used for the posttreatment of olive mill wastewater after anaerobic digestion. A factorial experimental design was adopted to determine the statistical significance of each parameter tested, namely, initial chemical oxygen demand (COD), pH, treatment time and recirculation flow and possible interactions in three response variables: phenols, color and CO...

Solar assisted Photo Fenton was compared with advanced oxidation processes for their color and COD removal efficiency and cost effectiveness. H2O2 alone appeared to be inefficient to reduce color and COD content of any effluent. The performance of Fenton process was slightly better, color and COD removals were 45 % and 63% respectively. Photo Fenton treatment of blue effluent resulted into colo...
