1. Technical parameters (1) flotation equipment commonly used mechanical reaction, the reaction time was 15 minutes. Upflow velocity (2) contacting zone flotation chamber was 47mm / sec, after the separation of 0.46mm / sec. (3) a reflux ratio is generally 30%, treated water is 0.25-0.4m3 / hr. Diving dissolved air impeller system This system is similar to the long axis of the vertical pump flotation equipment, technical parameters, the power placed in the upper part of the motor shaft through even with the lower dissolved air impeller connected. Diving dissolved air flotation tank in place at the time of the impeller, the motor above the water, submerged in water impeller flotation tank. Flotation devices sold in the impeller rotates, some return water back into the impeller housing. While producing a negative pressure within the housing, the intake air is connected to the atmosphere through the vent tube. Water mixed with return air after the formation of dissolved air impeller pressurized water directly distributed in the flotation pool. Flotation equipment manufacturers, flotation equipment, new environmental protection provided by Seoul Seoul Environmental Protection Equipment Co., Ltd. Weifang new.
