Biofilm processes utilize biofilm grown on carrier media to degrade soluble organic pollutants in the wastewater aerobically. These applications typically include a biological reactor filled with floating biomass carriers, a screen to prevent downstream migration of the carriers and an aeration grid.

MOVING BED BIOFILM REACTOR

The main characteristic of Moving Bed Biological Reactor (MBBR)

configurations is that there is no sludge recycle from a secondary clarifier. MBBR is essentially a simple, once-through process, where all of the biological activity takes place on the biomass carriers.

MBBR is usually followed by a solids separation system such as a secondary clarifier or DAF, in order to separate bio-solids produced in the process from the final effluent.

The main advantage of MBBR is robust and simple reduction of soluble pollutants (soluble BOD or COD, NH4+, etc.), with minimal process complexity, utilizing a significantly smaller footprint when compared to conventional aerobic treatment methods.

MBBR is typically used for either high load industrial applications or for robust simple-to-operate municipal facilities.

BIODOS incorporates cutting-edge biofilm technology in its wastewater treatment systems to efficiently break down organic pollutants. In this process, specialized biological reactors are equipped with suspended or fixed carrier media that support the growth of biofilm—microbial layers that actively degrade organic matter. As wastewater flows through the reactor, the biofilm consumes dissolved pollutants in the presence of oxygen supplied by an integrated aeration grid. To ensure stable operation, a screening system is installed to retain the biomass carriers within the reactor and prevent their escape downstream. This method offers high treatment efficiency, compact design, and low sludge production, making it ideal for both municipal and industrial wastewater applications. BIODOS’s biofilm systems are engineered for reliability, energy efficiency, and consistent performance in various operating conditions.
