Removal of reactive dyes from wastewater by magnesium hydroxide coagulation assisted with ultrasonic

摘要：

　　The effects of ultrasonic on the reactive dyes wastewater removal during magnesium hydroxide coagulation process were studied.The relationship between Fiocculation Index (FI) and removal ofchrominance was discussed with controlled experiments using on-line intelligent Particle Dispersion Analyzer (iPDA).The results showed that:Coagulation performance was better when increasing the ultrasonic intensity to 80W with the coagulation dose 144 mg/L and the solutions pH 12.0.The removal efficiency of reactive dyes was higher obviously with ultrasonic time 15s and 25s for dyes X-3B and X-R,respectively.The changes of zeta potential were also measured in coagulation process.
