Key Considerations When Investing In A Surface Wastewater Aerator

Surface wastewater aerators play a pivotal role in modern wastewater treatment processes, facilitating the biological degradation of organic waste materials. If you're in the market for a surface wastewater aerator, there are several factors to consider to ensure you choose the right solution for your needs.

Performance and Efficiency

The primary function of a surface aerator is to introduce oxygen into the water, and so the efficiency of oxygen transfer is a crucial consideration. This efficiency can vary considerably between models and manufacturers. 

Efficiency is generally given as a percentage, or as the amount of oxygen transferred per unit of power. High-efficiency models can save considerable energy and operating costs over time.

Durability and Maintenance

Aerators operate in a challenging environment, exposed to water, air, and biological material, often around the clock. Consequently, durability is paramount. 

Look for models made from corrosion-resistant materials, like stainless steel or high-quality plastics. Additionally, consider how easy the aerator is to service. Regular maintenance, including cleaning and part replacement, is vital for long-term performance.

Sizing and Design

The size and design of the aerator should be appropriate for your specific application. This consideration includes the volume of the water body, the type and quantity of waste, the desired rate of treatment, and any space or installation constraints. 

Discuss these factors with manufacturers or distributors to ensure you choose a suitably sized and designed unit.

Noise and Spray Control

Surface aerators can generate noise and spray, both of which can be problematic in populated areas. If this is a concern, look for models that are designed to minimize these issues. This might include aerators with shrouds or barriers to control spray, or models that operate at lower speeds to reduce noise.

Regulatory Compliance

Ensure that any aerator you consider meets all applicable local, state, and federal regulations. This might include environmental regulations, energy efficiency standards, or safety standards.


Consider the total cost of owning and operating the aerator. This includes not only the initial purchase price but also installation costs, energy costs, maintenance costs, and the potential costs of downtime or failures. A lower upfront cost might not represent the best value if the aerator is expensive to run or prone to breakdowns.

Environmental Impact

As environmental sustainability becomes an increasingly important consideration, it's crucial to consider the environmental impact of your surface wastewater aerator. The most eco-friendly aerators are designed to minimize energy use and reduce carbon emissions. Some models even leverage renewable energy sources, like solar or wind power, to operate.
