Late at night in the wastewater treatment plant, only faint lights flicker across the facility, yet the air system never rests. Every cubic meter of air acts like an invisible worker, churning the water in the aeration tanks to ensure efficient purification of wastewater as planned.

However, occasional air pressure fluctuations from traditional blowers have always caused anxiety among operators: insufficient aeration, high energy consumption, equipment overheating, and even fears of surprise inspections from environmental protection authorities.

Old Pain Points: The Hidden Burden of Traditional Blowers

The air system in wastewater treatment plants requires continuous and stable operation; any fluctuations in air pressure can affect aeration efficiency.

Oil-contaminated air easily pollutes pipelines and aeration devices.

Under peak loads, air pressure fluctuates unpredictably, leading to unstable aeration uniformity.

High energy consumption and noise levels keep operational costs elevated.

Pressure from environmental inspections is high, and non-compliant air emissions pose potential risks.

Long-term reliance on traditional equipment has kept plant managers in a constant state of tension: on one hand, ensuring treatment efficiency, and on the other, managing compliance pressures.

Against this backdrop, three units of 75 kW oil-free screw blowers quietly went online, becoming the plant’s new "green guardians."

Variable Frequency Control: Air Pressure Adjusts on Demand

After installing AIRHORSE oil-free screw blowers, bubbles in the aeration tanks surged as expected during peak hours, while the equipment automatically reduced speed to save energy during low-load periods. The intelligent variable frequency control system ensures that air supply precisely matches the load without manual intervention, maintaining air pressure as steady as a heartbeat.

"Previously, air pressure fluctuations occurred during every peak hour, leading to insufficient aeration. Now, the air supply is stable from startup, making the entire process much smoother."

Stable Quality: Oil-Free Air, Worry-Free Environmental Compliance

AIRHORSE 75 kW oil-free screw blowers produce completely oil-free emissions, ensuring clean and safe air. Aeration pipelines remain consistently clean, significantly reducing equipment maintenance. More importantly, air emissions fully comply with environmental standards, eliminating concerns about surprise inspections.

A site customer remarked, "We used to worry constantly about environmental inspections and whether our air emissions met standards. Now, we have no such worries—even if inspections come, we’re not afraid."

Energy Savings: Efficient Operation, Reduced Costs

For continuously operating wastewater treatment plants, electricity expenses are a major cost. AIRHORSE blowers combine low-speed, high-airflow design with intelligent variable frequency adjustment, ensuring every kilowatt-hour is used effectively.

Actual operational data shows a noticeable reduction in electricity costs, with energy-saving effects clearly visible, enabling the company to simultaneously achieve environmental protection and cost optimization.

Smart Operations: Easier Maintenance, More Reliable Production

The equipment is equipped with an intelligent monitoring system that collects key data such as pressure, flow rate, and current around the clock, providing early warnings for potential risks. Maintenance personnel no longer need to conduct daily on-site inspections. Instead, they can monitor equipment health in real time through the system, enabling proactive maintenance and ensuring more reliable production with easier operations.

After the three units of 75 kW oil-free screw blowers went online, the wastewater treatment plant in Guangxi gained an "invisible guardian": air pressure stabilized, aeration uniformity significantly improved; oil-free air eliminated pollution concerns, easing environmental inspection worries; energy-saving measures reduced operational costs; and intelligent monitoring made operations more efficient and effortless.

Under the dual pressures of environmental protection and efficiency, AIRHORSE oil-free blowers have become a reliable support for the plant’s safety, environmental compliance, and energy conservation. They not only power production but also provide peace of mind for every operator and manager, freeing them from past concerns.
