Case Studies: Performance Comparison of MBR and MBBR
To make an informed choice between MBR and MBBR technology for your home sewage treatment plant or industrial wastewater treatment equipment, we need to examine their performance in various applications. Below are two case studies comparing MBRs and MBBRs.
Case 1: Domestic Sewage Treatment Plant
An MBR plant was added to a small-scale treatment facility serving 10,000 inhabitants. The effluent quality of the MBR process was excellent, achieving removal efficiencies of over 95% for suspended solids (SS) and biochemical oxygen demand (BOD). The membrane barrier in the MBR system effectively separated contaminants, producing high-quality treated effluent for environmentally sound wastewater disposal.
In contrast, a similarly sized domestic sewage treatment plant adopted an MBBR process. The MBBR process also performed well, achieving 90% removal of suspended solids and BOD. The MBBR reactor, with its biofilm carriers, provided a higher surface area for microbial attachment, improving biological treatment. However, the final effluent quality from the MBBR system was slightly inferior to that of the MBR, necessitating further tertiary treatment for discharge.
Case 2: Industrial Wastewater Treatment Plant
For treating effluent from a food processing plant, MBR technology was selected due to its strength in treatment. The combined MBR treatment efficiently eliminated organics and nutrients from the wastewater, achieving low discharge limits imposed by regulators. Membrane filtration in the MBR provided stable and consistent treatment performance, even with changes in influent quality.
Conversely, an industrial wastewater treatment plant in a chemical production facility chose the MBBR process for its versatility and cost-effectiveness. The MBBR technology successfully treated complex industrial effluents, achieving 85% removal efficiency for organic pollutants. The load-following characteristic and shock load accommodation of the MBBR reactor proved beneficial for effective treatment from various wastewater sources.
