Abstract :In this study, we conducted a novel method by using a household type Microwave Owen insert ignore into journalissuearticles values(MW); under selected operational parameters insert ignore into journalissuearticles values(power and time); to treat wastewater from paper recycling under laboratory conditions. We seek to evaluate changes of the MW experimental parameters, comparatively. All measured pH values were found to be in very narrow range, between pH 7.10 insert ignore into journalissuearticles values(BII); and pH 7.53 insert ignore into journalissuearticles values(DIV);, in slightly alkaline range insert ignore into journalissuearticles values(>7.0);. However, the highest Electrical Conductivity insert ignore into journalissuearticles values(EC); difference was found to be 46 µS/cm. The 60 seconds MW irradiated samples at four power levels insert ignore into journalissuearticles values(90-, 180-, 270-, 360 Watts); showed higher ORP values than control insert ignore into journalissuearticles values(C1: 195 mV); while the highest ORP value of 213 mV was found with sample treated 360 W and 60 seconds insert ignore into journalissuearticles values(DIV);. It is notable that sample DIV showed the highest pH, EC, ORP and TDS value. The control sample had turbidity value of 42.5 NTU. In all MW power levels and durations, turbidity removal was apparent which MW impact on turbidity. The lowest turbidity value of 22.2 NTU was found with sample DIV which was the highest rate of turbidity removal efficiency insert ignore into journalissuearticles values(DIV: 86.2%);. The present study revealed that MW irradiation could be used to effectively reduce the selected physicochemical parameters that may assist in the description of wastewater quality.
