Maximizing Efficiency: The Value of Regular Maintenance for Wastewater Aeration Equipment

Written by: Ray Hedelson, Product Development Engineer – Newterra

Wastewater treatment plants play a crucial role in safeguarding public health and the environment by efficiently treating wastewater before it is discharged back into natural water bodies. Central to this process are aeration systems, which rely on blowers and electric motors to oxygenate wastewater, facilitating the breakdown of organic matter by beneficial bacteria. However, like any mechanical system, aeration equipment requires regular maintenance to ensure optimal performance and longevity.

Regular Maintenance

One of the key components of aeration systems is the blower. These devices are responsible for delivering the necessary airflow to support biological processes within the treatment tanks. Over time, factors such as dust, debris, and normal wear and tear can lead to decreased efficiency and potential breakdowns. Regular maintenance, including cleaning, filter replacement, lubrication, and inspection of components, can help prevent these issues and ensure that blowers operate at peak efficiency.

Similarly, electric motors play a vital role in powering aeration equipment. These motors drive the blowers and other mechanical components, making their proper functioning essential for the overall performance of the wastewater treatment plant. Routine maintenance tasks such as checking for overheating, lubricating, inspecting electrical connections, and replacing worn-out parts can help prevent costly downtime and extend the lifespan of electric motors.

Investing in regular service for wastewater aeration equipment offers numerous benefits, foremost among them being the preservation of system efficiency. By ensuring that blowers and electric motors operate at their best, treatment plants can maintain optimal oxygen levels in the wastewater, promoting efficient microbial activity and speeding up the treatment process. This leads to reduced energy consumption and operating costs, as well as compliance with environmental regulations.  Furthermore, proactive maintenance helps to mitigate the risk of unexpected breakdowns and costly repairs. By identifying and addressing potential issues before they escalate, treatment plant operators can avoid unplanned downtime and maintain uninterrupted wastewater treatment operations. This reliability is essential for meeting regulatory requirements and upholding the public’s trust in the effectiveness of the treatment facility.

Servicing Wastewater Aeration Equipment

When it comes to servicing wastewater aeration equipment, partnering with a trusted provider with expertise in this area is paramount. Newterra stands out as a leading company specializing in water treatment solutions, offering comprehensive maintenance services tailored to the unique needs of each facility.  

A comprehensive Newterra maintenance plan will include the following (at minimum):

  • Daily Observations:  Observing each piece of equipment (aerators, mixers, etc.) daily to for visual and audible signs of problems.  Equipment should run smoothly without excessive vibration or noise.  Water flow and air from the aerator or mixer can be noted.  Noise, vibration, and disrupted air or water flow are indicators of operational problems.   
  • Preventative Maintenance & Inspection Items:  A maintenance schedule & record sheet will be provided to assist operators in maintaining the equipment.  Quarterly maintenance items typically include routine cleaning and removal of debris, bolt & hardware inspection, blower filter inspection, and electrical connection check.  Other (less frequent) maintenance items include electric motor greasing (typically 6 months, or per motor manufacturer recommendation), aerator shaft assembly greasing (yearly), and measuring & recording all electrical readings (yearly).

With our team of experienced technicians and commitment to quality, Newterra ensures that aeration equipment is maintained to the highest standards, delivering a tangible return on investment for treatment plant operators.

In conclusion, regular maintenance of wastewater aeration equipment, particularly blowers and electric motors, is essential for maximizing efficiency, minimizing downtime, and ensuring regulatory compliance. Investing in proactive service not only extends the lifespan of equipment but also yields significant cost savings and operational benefits in the long run. With Newterra’s expertise in maintenance services, treatment plant operators can rest assured that their aeration systems are in capable hands, allowing them to focus on their core mission of protecting public health and the environment.
