Optimum Aeration of Wastewater Treatment Plants
Efficient wastewater aeration is essential for stable biological processes. With modern, energy-efficient technology, DAS EE ensures an optimum oxygen supply, reliable compliance with limit values and economical plant operation.
Efficient Aeration for Stable Biological Processes
Reliable wastewater aeration is crucial for the success of biological treatment processes. In the treatment of industrial wastewater, it ensures that microorganisms receive the necessary oxygen - for a high degradation rate of organic substances, constant water quality and stable process conditions. Our tailor-made aeration systems enable uniform oxygen distribution and maximum efficiency with minimum energy and maintenance requirements.
With customized solutions, we ensure that your biological wastewater treatment is not only environmentally friendly, but also economical and reliable - no matter how demanding your requirements are.
Flexible Wastewater Aeration with Jet Aerators
Jet aerators are ideal for use in MBBR (Moving Bed Biofilm Reactor) or activated sludge plants. They are also the preferred choice when the task of wastewater treatment is to remove lime as well as large solids and sludge and also to enable separate operation of mixing and aeration.
One such example is the degradation of nitrate nitrogen, which requires mixing of the wastewater without the introduction of air. The use of jet aerators is also advantageous for wastewater containing lime, which is produced in waste paper processing. The limescale deposits clog membrane aerators at the bottom of the tank, which have to compensate for the pressure loss with ever-increasing power. Replacing the membranes with jet aerators eliminates this problem. In addition, jet aerators introduce more oxygen into the water, which can significantly increase COD reduction in the same volume.
Your Advantages
Strong circulation & efficient air intake (separately controllable)
Special nozzle design effectively prevents sludge accumulation at the bottom & keeps solids in suspension
Mobile solution enables maintenance during operation
No moving parts → No special maintenance required
Other Waste Water Aeration Systems
Immersion Rotor Aerator
If aeration of the wastewater is also to be combined with mixing of the biomass, submersible rotor aerators are established as active systems.
Perforated Tubes
For uncomplicated wastewater in high-load stages (MBBR), perforated pipes are used, which are characterized by medium-bubble aeration.
Membrane Aerator
If the laboratory analysis shows that the wastewater has a low lime content, membrane aerators are preferably used in the activated sludge plants.
