Aeration systems for wastewater treatment plants
Geotierre’s wastewater aeration technology is the result of decades of application experience with aeration systems for municipal, domestic and industrial wastewater treatment plants. Our air diffusers are designed to promote oxygen transfer, improve transfer efficiency and ensure uniform air distribution throughout the tanks.
The range includes fine- and coarse-bubble aeration systems, with solutions suitable for a variety of wastewater treatment applications, including industrial and municipal wastewater, biological oxidation tanks, nitrification tanks, aerobic digestion, grit removal and oil separation.
Where Geotierre diffusers are used
Geotierre aeration systems can be used in a wide range of applications.
The benefits of aeration with air diffusers
Oxygen transfer through air diffusers is an efficient and advantageous solution compared with other aeration systems.
This technology distributes air evenly throughout the tanks and allows the airflow to be adjusted to the plant’s actual requirements.
Energy efficiency
In terms of energy performance, diffuser aeration systems can achieve high oxygen transfer rates, helping reduce the plant’s energy consumption.
Optimising the supplied airflow makes it possible to adapt operation to actual conditions and avoid wasting energy.
Greater protection for electromechanical equipment
In air diffuser systems, electromechanical equipment can be located in technical rooms away from the tanks.
This provides greater protection from the operating environment and makes the equipment more accessible for inspections, maintenance and routine management.
Continuous airflow control
The supplied airflow can be adjusted continuously to match the requirements of the biological process.
This flexibility improves plant management and delivers significant energy savings.
Reliability under different operating conditions
Air diffuser aeration systems do not adversely affect the treated water and reduce the risk of problems associated with ice formation in the tanks. They can also deliver energy savings of up to 70% compared with other systems.
Aeration systems for wastewater treatment
Key aspects of wastewater aeration systems: components, functions and selection criteria for biological processes in domestic and industrial plants.
Diffuser aeration systems can deliver energy savings of up to 70% compared with other systems, thanks to high oxygen transfer rates and the ability to continuously adjust the supplied airflow.
They can be used in a wide range of applications: industrial and municipal wastewater treatment, drinking water treatment, aquariums and aquaculture, fish farming, sludge stabilisation and digestion, grit removal and oil separation, aerobic digestion, nitrification tanks and biological oxidation tanks.
Because the oxygen demand of the biological process varies over time. Continuous airflow control matches the flow to the plant’s actual requirements, avoiding energy waste and improving overall management.
It can be located in technical rooms away from the tanks, providing greater protection from the operating environment and easier access for inspections, maintenance and routine management.
No. Air diffuser aeration systems do not adversely affect the treated water and reduce the risk of problems associated with ice formation in the tanks.
The Geotierre team can help you select the most appropriate aeration system based on tank type, airflow requirements and treatment needs.
