The term "Rotordisk" refers to a crucial component within a specific type of wastewater treatment technology: the Rotating Biological Contactor (RBC). Developed by the CMS Group, Inc., RBCs are an efficient and sustainable solution for removing organic pollutants from wastewater.
Understanding the Rotordisk:
The Rotordisk is essentially a circular plastic disc with a high surface area designed to support the growth of biofilm. This biofilm, a complex community of microorganisms, plays a vital role in the wastewater treatment process.
