For special applications in the field of wastewater aeration, our product portfolio also includes the JetFlex® CBD coarse-bubble diffuser. This is available both in a disk design (JetFlex® CBD 105) and as a stainless steel tube diffuser (JetFlex® CBD SS). Used in the grit chamber of a sewage treatment plant, in the equalization tank, in sludge stabilization tanks or as secondary aeration, they offer the possibility of running at a high airflow and thus mix the medium in the best possible way or ensuring a certain oxygen concentration in the effluent. In addition, the diffuser can be used in aeration tanks to induce vertical flows and thus prevent sludge deposits on the tank floor.
