A Roots blower is a type of positive displacement blower used in wastewater treatment plants (WWTP) primarily for aeration purposes, helping to provide oxygen to activated sludge processes or to drive other processes requiring airflow.
| Step | Description | Purpose/Function |
|---|---|---|
| 1. Air Intake | Air is drawn into the Roots blower through the inlet port. | Supply air to the system for aeration. |
| 2. Rotor Rotation | Two rotors rotate in opposite directions, trapping air between the lobes. | Compress and move the air without significant compression. |
| 3. Air Compression | As the rotors rotate, air is trapped and pushed towards the discharge port. | Create consistent airflow to maintain aeration in treatment tanks. |
| 4. Air Discharge | The air exits the blower through the exhaust port and is sent to the aeration system. | Deliver air into the wastewater for oxygen transfer. |
| 5. Air Distribution | The air is diffused through diffusers or spargers into the wastewater. | Oxygenate the water, supporting microbial activity in biological treatment. |
| 6. Aeration in Tanks | Fine air bubbles are released into aeration tanks, ensuring even oxygen distribution. | Promote aerobic respiration for breaking down organic waste. |
