Companies that produce wastewater need to determine several factors to calculate the most effective design for their MBBR system. These factors include the surface area loading rate (SALR) along with wastewater flow rate and nitrate, ammonia or BOD concentration. These factors can help determine the necessary carrier surface area and tank volume for a successful MBBR process. Calculations differ depending on whether the goal is single- or two-stage BOD removal, single-stage nitrification, two-stage BOD removal and nitrification, post-anoxic denitrification or pre-anoxic denitrification.
For example, when the system remains in continual operation, there is no need for return sludge flows or backwashing. Because the aeration grid keeps the media moving around in the tank, clogs are not an issue. Because the system self-moderates to provide the optimum amount of productive biofilm, operators don't need to take any action to maintain the correct food to microorganism ratio (F/M).
