kiinteäkerrosliukukalvobioreaktorit

Kiinteäkerrosliukukalvobioreaktorit, often abbreviated as MBBR (Moving Bed Biofilm Reactor), are a type of wastewater treatment technology that utilizes a biofilm growth system. In this reactor design, small, plastic carriers are suspended in the wastewater. These carriers provide a large surface area for beneficial microorganisms to attach and grow, forming a biofilm. The wastewater flows through the reactor, and as it passes over the carriers, the microorganisms in the biofilm consume organic pollutants and nutrients. The carriers are kept in constant motion by the aeration of the wastewater or mechanical mixers, which prevents clogging and ensures good contact between the wastewater and the biofilm. This constant movement also helps to slough off excess biomass, maintaining an optimal biofilm thickness. MBBR systems are known for their compact size and high efficiency in treating both municipal and industrial wastewater. They are particularly effective in reducing biochemical oxygen demand (BOD) and chemical oxygen demand (COD). The submerged nature of the biofilm on the carriers offers resilience against variations in wastewater flow and composition. This technology can be implemented in various configurations, including as a standalone system or as an upgrade to existing conventional wastewater treatment plants.
