Study On Treating The Textile Wastewater By Electro Coagulation Process Using Mild Steel As Electrode
Textile Industries are among the most polluting industries which usually use large amount of water and various chemicals for finishing and dying process. Electrocoagulation process recently it gained an immense attention due to its efficiency, The experiment is conducted for improving textile effluent quality via removal of turbidity, color, total dissolved solids and chemical oxygen demand by electro coagulation using mild steel as anode and cathode. Electrocoagulation method is an advanced technology which is able to treat textile waste water having high COD,TDS, and color efficiency before it is treated further or discharged in to water bodies. And this method is considered as effective method to removal of dyes from colored waste water. The electrochemical cell consists of both electrode and cathode placed vertical to each other. DC power supply (0-30 Volts and 0-5A) was used as a power source. The terminals worked in monopolar mode. Effluents were treated for 10 volts, 20 volts and 30 volts for 20 min intervals until it becomes clear. The results are reported in terms of percentage removal of COD, color by varying pHand current density; it was observed that increasing the current density will decolorize and reduce the COD percentage by 80% to 90%.
