The wastewater is aerated with rotary lobe blowers to provide the micro-organisms with oxygen. Busch Vacuum Pumps and Systems launched a new series of rotary lobe blowers for this application that ensure reliable oxygen injection. When it comes to aerating aeration tanks in wastewater treatment facilities, mechanical rotary lobe blowers have become the first choice among the technologies that can be used for overpressure generation. With the new Tyr rotary lobe blowers (fig. 1), Busch Vacuum Pumps and Systems has sought to s
