Aeration is typically the single largest energy consumer in wastewater treatment plants, often accounting for more than half of total plant electricity usage. Achieving the right balance between air delivery and oxygen transfer is essential to reduce operating costs while maintaining process performance.
At Ökotechnik, we help wastewater treatment facilities optimize their aeration systems through the integration of high-efficiency Robuschi blowers and advanced SSI diffuser technologies, delivering reliable, energy-efficient solutions tailored to each application.
We are all part of the same company group, Ingersoll Rand.
An efficient aeration system requires more than selecting a blower or a diffuser independently. True optimization considers the entire air delivery chain, including:
By combining Robuschi blower technology with SSI's proven diffuser solutions, we deliver a fully integrated approach that maximizes performance and long-term value.
Every wastewater process has unique operating requirements. Robuschi offers a complete portfolio of blower technologies to match different flow rates, pressure demands and control strategies.
Rotary Lobe Blowers
Reliable and robust solutions for applications requiring durability and continuous operation.
Benefits:
Screw Blowers
Designed for superior energy efficiency and optimized lifecycle costs.
Benefits:
Turbo Blowers
The ideal choice for facilities targeting maximum energy savings.
Benefits:
The diffuser system plays a critical role in determining aeration efficiency.
SSI's advanced diffuser technologies are designed to achieve high oxygen transfer rates while ensuring durability and consistent performance over time.
Fine Bubble Diffusers
Fine bubble diffusion increases oxygen transfer efficiency by producing a large number of small bubbles with greater surface area.
Key advantages:
Engineered for Long-Term Reliability
SSI diffuser systems are designed to provide:
Installing an efficient blower without optimizing the diffuser system can limit potential energy savings. Likewise, high-performance diffusers require the right blower technology and control strategy to deliver maximum benefits.
An integrated optimization approach provides:
Lower Energy Consumption
Efficient air production combined with high oxygen transfer performance reduces overall power requirements.
Reduced Lifecycle Costs
Lower energy use and minimized maintenance contribute to a lower total cost of ownership.
Improved Process Stability
Precise airflow control ensures consistent dissolved oxygen levels and biological treatment performance.
Future-Proof Flexibility
Systems can adapt to seasonal load variations, plant expansions and evolving process requirements.
