SHAFT-TYPE JET SIPHON AERATOR

摘要

The invention relates to devices providing saturation of mixture of water to be purified and recirculated activated sludge with oxygen, and maintaining the activated sludge in fluidized state, namely to a shaft-type siphon aerator of corresponding structure, using which a high flow turbulence is developed, thereby mass exchange of the aerated sludge mixture is increased at high efficiency of gas use and low energy consumption.
