aims: textile wastewaters are the most important health and environmental problems in kashan. this research was aimed to compare the poly aluminum chloride and chlorinated cuprous efficiency for removal of chemical oxygen demand (cod) and color from kashan textile industries company wastewater. materials & methods: this experimental bench scale study in a batch system was conducted on 20 compos...

textile industry is the major source of water consumption and wastewater pollution.there are various treatment techniques to remove textile wastewater pollution. coagulationflocculation is a widely used process to remove pollution due to suspended particles. in this research, different coagulants like alum, lime, fecl3, feso4 and mgcl2 were applied to select the suitable ones with optimum remov...

Nanoscale zero-valent iron NZVI particles were synthesized by the aqueous phase borohydride reduction method, and the synthesized NZVI particles were used for the degradation of Basic Yellow 28 BY28 dye in aqueous solution. The influence of experimental variables such as reaction time, NZVI particle dosage and pH were studied on the decolorization of BY28. Mixing an aqueous solution of 100 mg L...

A method is explored to remove tall building shadows in true color and color infrared urban aerial images based on the theory of color constancy. This paper first uses the specthem ratio and Otsu threshold segmentation methods to detect building shadows on urban aerial true color and color infrared aerial images. Then, based on the shadow detection result, one of the color constancy algorithms ...

a floating polymer-supported photocatalyst based on polystyrene impregnated with titaniumdioxide particles was developed using a facile solvent-cast method at ambient temperature. the preparedphotocatalysts were characterized by x-ray diffraction, scanning electron microscopy and fourier transforminfrared spectroscopy. the photocatalytic activity of the developed photocatalysts was investigated...

Background & Aims of the Study: Coagulation is an essential process for the removal of fine particulate matter in water treatment. Polyaluminium ferric chloride (PAFC) is a composite inorganic polymer of Aluminium and ferric salt. This study was conducted to find out the optimum coagulation conditions for the removal of turbidity, color and organic matter (UV absorbance) in low to mediu...

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 re...
