Whole Aeration system included the aerator(bubble diffuser) gas distribution pipes, tees, crosses, elbows, regulators, connectors, cleaning devices and other components. Usually gas distribution pipelines is the usual circular arrangement, diffuser quantity is according to the air capacity and ponds size. The diffuser and gas distribution pipelines using G3 / 4 threaded connection, the base is inner thread (fixed in the pipeline), diffuser is externally threaded.
1. Aeration for SBR reaction basin, contact oxidation pond, and activated sludge aeration
basin in sewage disposal plant;
2. Aeration for denitrification / dephosphorization aerobic processes;
3. Aeration for excreta and animal wastewater treatment plant;
4. Aeration of deep aeration basin;
5. Aeration for high concentration wastewater aeration basin, and aeration for regulating pond of wastewater treatment plant;
6. Aeration of fishpond and other applications.
2.Tight sealing without air leakage
