The AERZEN wastewater aeration technologies IFAT 2026 showcase introduces a range of new blower and turbo systems designed to improve energy efficiency, operational flexibility and digital control in wastewater treatment processes.
Presented at IFAT in Munich, AERZEN highlighted several innovations focused on aeration systems, a key component in biological wastewater treatment where energy demand is typically highest.
New screw blower sizes expand flexibility in aeration systems
AERZEN has extended its Delta Hybrid screw blower range with new models designed for lower volume flow applications. These systems are intended to provide greater flexibility for operators working across varying performance requirements.
The new units are designed to deliver oil-free process air and improved efficiency across a wide operating range. According to the company, energy savings of up to 37% compared to conventional blower technologies are achievable, alongside extended turndown capabilities.
This expansion supports more precise system design, particularly in smaller-scale or variable-load aeration environments.
Generation 6 turbo blowers introduce improved efficiency and digital control
The new Generation 6 turbo blower range is designed to support demanding aeration processes within biological treatment stages. These systems combine compact design with enhanced energy performance and improved process control.
The units feature integrated digital control systems with IoT connectivity, enabling more transparent monitoring and optimisation of aeration processes. Energy efficiency improvements of up to 15% compared to previous technologies have also been reported. :contentReference[oaicite:1]{index=1}
Enhanced turndown ratios allow the systems to adapt to fluctuating oxygen demand within treatment processes, improving operational efficiency.
High-capacity turbo stage targets large-scale applications
AERZEN also introduced a new turbo stage designed for higher volume flow requirements, supporting large-scale wastewater treatment operations. The system is intended to provide increased capacity while maintaining energy efficiency and operational flexibility.
This development expands the company’s turbo portfolio into higher performance ranges, enabling its use in more demanding aeration scenarios.
What AERZEN wastewater aeration technologies IFAT 2026 means for the sector
The AERZEN wastewater aeration technologies IFAT 2026 announcement reflects a wider focus within the wastewater sector on reducing energy consumption and improving system optimisation.
Aeration is one of the most energy-intensive processes in wastewater treatment, often accounting for a significant proportion of plant operating costs. As a result, improvements in blower efficiency and control systems can have a substantial impact on overall plant performance.
Technologies that enable flexible operation, including wide turndown ranges and real-time monitoring, allow treatment plants to respond more effectively to variable inflows and changing biological conditions.
Digitalisation is also playing an increasing role, with connected systems enabling predictive maintenance, condition monitoring and improved process control.
