this study evaluates the effectiveness of adsorption process by granular activated carbon (gac) compared with a novel formulation of coagulation - flocculation process for dye removal from textile wastewater. in this regard, acidic, reactive, disperse and direct red dye are used to prepare the synthetic dye. dominant wave length for each dye is determined by spectrophotometeric method. using ga...

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 ...

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...

the optimization of process conditions for the degradation of acid blue 193 by uv/peroxydisulfate was investigated using response surface methodology (rsm). the effects of four parameters namely initial k2s2o8 concentration, uv irradiation, temperature, and initial dye concentration on two process responses, color removal and the rate constants of the first-order kinetic equations, were investi...

the color removal of three reactive dyes in an aquatic system without priortreatment was studied. selected commercial dyes were treated with nac102 anduv as oxidation agents. effects of nature of oxidant, temperature, ph ofsolutions, concentration of c107—, contact time of c102— and uv irradiation wereinvestigated. optimal c102— concentration for color removal in the absence of uvirradiation wa...

This paper present the design and function of magiran.com, a databse of periodicals published in Iran. It also attempts to answer the following questions: How many of the total periodicals published in Iran are covered by magiran? What is the subject coverage of the periodicals covered? Which subjects seem to have been given importance among the periodicals covered? How many of the periodicals ...

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...

Color interpolation solutions drastically influence the quality of the whole image generation pipeline, so they must guarantee the rendering of high quality pictures avoiding typical artifacts such as blurring, zipper effects and false colors. Moreover, demosaicing should avoid emphasizing typical artifacts of real sensors data, such as noise and green imbalance effect, which would be further a...
