AerGrid
High Efficiency Coarse Bubble Floor Grid Systems
Aertec provides cutting edge technology for applications from mixed limited to high rate, including high solids suspension applications. The AerGrid layout allows the designer the flexibility to put aeration where it is needed. The system may be installed in dry and wet environments and by divers, if required. AerGrid efficiency improves as airflow increases using either full floor or tapered coverage. The basic elements of the system include diffuser laterals. These are attached to the bottom of the tank or basin by a patented yoke assembly fixed to the floor or ballast block shown below. Generally AerGrid systems are installed in the dry, but special installation techniques can be installed by diver crews.
