Tideflex Technologies’ aeration system combines coarse and fine bubble aeration components to improve mixing and oxygen transfer while preventing backflow and clogging. The custom engineered system uses the Tideflex TFA coarse bubble diffuser to provide rapid mixing while the Tubeflex Fine Bubble Air Diffuser provides the fine bubble supplement. This combination increases transfer efficiency due to the entrainment in higher velocity loops created by the TFA. The air diffusers incorporate patented Check Valve technology. The combined system reduces energy use and lowers total airflow requirements.
