Operation data of VACOMASS air distribution and control systems used in 1#aeration tank of the Shaoxing Sewage Treatment Plant's third project were analyzed. The results showed that the dissolved oxygen concentration could be stably controlled within the setting range( ± 0. 5 mg / L). The air saving rate was 25% to 50% while simultaneously ensuring stable dissolved oxygen concentrations in the aeration tank and stable operation of biochemical unit,thereby reducing energy consumption and operation costs of the aeration unit.Read More
