Optimize the aeration system: Aeration energy consumption typically accounts for over 50% of the total energy consumption in wastewater treatment, making it a key area for energy conservation.
Replacing traditional Roots blowers with variable frequency aeration blowers or magnetic levitation/air levitation blowers can save approximately 30% of energy.
Installing an online DO (dissolved oxygen) monitor enables on-demand oxygen supply, avoiding over-aeration; controlling DO at 2–3 mg/L is sufficient to meet treatment requirements.
Upgrade to high-efficiency, energy-saving equipment:
Variable frequency technology: Installing frequency converters on high-power equipment such as pumps and blowers automatically adjusts speed based on flow rate and pressure, achieving energy savings of 20%-30%.
Selecting high-efficiency motors, energy-saving pumps, and low-power aerators improves overall energy efficiency.
