Title
The Effects of Initial Boron Concentration on Energy Consumption in Boron Removal by Electrocoagulation
Abstract
In this study, it was investigated initial boron concentration affecting energy consumption in boron removal from boron containing wastewaters prepared synthetically, via electrocoagulation method. Initial boron concentration of solution was selected as experimental parameter affecting energy consumption. The other parameters such as solution pH, current density and temperature of solution were kept constant during reaction time. Experiments were carried out with different initial boron concentrations ranging from 100, 250, 500 and 1000mg/L. Increasing initial boron concentration caused to increase specific conductivity of solution. Specific conductivity of solution was a important parameter on energy consumption of electrocoagulation system. The higher specific conductivity of solution caused to the lower energy consumption values. While energy consumption value was 49,87 kW-h/m3 for 100 mg/L initial boron concentration, this value was decreased to 14, 3 kW-h/m3 for 1000 mg/L initial boron concentration under 3.0 mA/cm2 of current density, pH 8.0, 293 K of solution temperature and 150 rpm of stirring speed.
