Mixing and aeration of liquids is commonly used for a variety of industrial process reasons as well as for wastewater treatment. For municipal biological wastewater treatment, mixing and aeration are used to add large amounts of oxygen to the wastewater (with the lowest possible energy consumption). The oxygen concentration and the activated sludge particles are always uniformly distributed to avoid sedimentation.
INVENT are Europe’s market leader and developed the hyperboloid stirring aeration system. They have a wide range of quality engineered, cutting edge equipment, from dedicated mixers, and combined mixer/aeration systems to specific aeration systems for both tank and pond operations. Their most popular product is the multi-purpose HyperClassic range.
Systems are designed by INVENT to suit each specific project and warranties are provided accordingly.
- Highly efficient mixing and aeration in one piece of equipment
- Mechanical aeration means the oxygen transfer performance is nearly as high in wastewater as it is in pure water
- Can be installed easily even in a filled tank, with a pre-mounted cage option or the HyperDive submersible option
How it Works
PRODUCT EXAMPLE: HYPERBOLOID MIXER
The hyperboloid mixer/aerator rotates close to the bottom and its 8 integrated and specially optimized motion fins produce a bottom flow which is directed radially outwards. Particularly at the bottom, this flow is highly turbulent and effectively whirls up any depositions.
During the aeration mode, air or gas is blown under the hyperboloid mixer-body via a separate pipeline and specially designed sparger system. As the mixer-body rotates, the air in the dispersing tunnels is mixed intensively with the wastewater and is torn into the smallest bubbles by the shear fins.
