Abstract: This work describes a simple and effective pretreatment process to remove the SS content and ease the subsequent processing burden and reduce suspended organic solids in bleached shellac wastewater by the thermal coagulation method. The methods of single factor and the response surface are used for this experiment. Meanwhile the optimum experimental conditions can be obtained such as reaction temperature of 55 ℃, thermostatical time of130 min and stirring rate of 80 r/min. The value of SS, turbi... More
