HOW DOES MBBR COMPARE TO OTHER BIOLOGICAL PROCESSES?
Having discussed biological processes of wastewater treatment, and the distinctive advantages of MBBR, it's still beneficial to note how MBBR compares to other biological processes. Many plant operators or consulting engineers who are interested in MBBR are currently using other biological processes in their treatment of wastewater, so it's helpful to make some direct comparisons.
There are many types of biological wastewater treatment processes, but two of the most popular modes of aerobic biological wastewater treatment are activated sludge and trickling filter.
ACTIVATED SLUDGE PROCESS VS. MBBR
The activated sludge process (ASP) shares some similarities with MBBR. With this traditional process, wastewater enters an aeration tank that contains high levels of oxygen. This oxygen aids in the process of microbial growth and decomposition of organic waste. The water then moves onto a settling tank, where the remaining waste in the water will separate from the water, leaving it cleaner.
The activated sludge process is a tried-and-true method for biological wastewater treatment. However, research has shown that, under optimal conditions, MBBR can more effectively remove chemical oxygen demand and can more effectively handle organic loading compared to ASP. MBBR takes advantage of the same strengths ASP provides and offers additional benefits that make it superior technology.
TRICKLING FILTER PROCESS VS. MBBR
Another popular treatment is the trickling filter process. This process uses a bed of material, such as gravel, rocks, ceramic or plastic, to hold onto microorganisms in water as it passes over the layer of material. These microorganisms will create a biofilm over time that will then decompose organic matter contained in wastewater. Periodically infusing oxygen into the water can make the environment more aerobic.
This process cannot compete with MBBR when it comes to efficiency or ease of operation. In the case of trickling filter processes, a skilled operator must closely monitor the process. Clogs are a common issue with this process, but they rarely happen in the case of MBBR.
