In waste water treatment system, there are many process need roots air blowers, for example, ventilation or gas collecting/treating, aeration, back-washing, etc.

For ventilation, it uses centrifugal fan usually. Centrifugal fans have a wider range of flow rate, lower pressure than roots air blower. In this way, it is proper for ventilating.
For aeration and back-washing, roots air blower is the better choice. For roots blower has a large pressure range, it can realize pressure differential from 9.8 to 98kPa, our HDSR series three lobe roots blower's flow rate is from 0.67 to 198.1m3/min, fitting for aeration's needs.
