What Are RBCs and Rotary Distributors?
Rotating Biological Contactors (RBCs) are fixed-film biological treatment units where microbes grow on rotating media. As the media rotates through wastewater and air, it supports aerobic biological treatment without the need for aeration blowers.
Rotary Distributors are used in trickling filter systems, rotating arms to evenly distribute wastewater over filter media, ensuring even biological activity and treatment efficiency.
