Webinars – Introduction to FMBR

Schedule a Free Private Educational Session for Your Organization

This virtual educational session is designed as a private event for organizations interested in learning more about the Facultative Membrane Bio-Reactor (FMBR). FMBR is a new Membrane Bio-Reactor (MBR) to the USA that provides a compact, efficient, decentralized wastewater treatment system (DEWATS) and a new option to consider for upgrading and expanding the capacity of centralized WWTPs.

Jim Cheng, PhD, of JDL Global, LLC will provide a 30 minute overview of FMBR technology, including results of the Plymouth Pilot Demonstration and Microbe Detectives’ DNA Benchmarking Study. This will be followed by a 30 minute open Q & A discussion. John Tillotson of WaterTrust will serve as the host.

The FMBR Pilot Demonstration, Plymouth Massachusetts Municipal Airport

From November 2019 to December 2020, the Plymouth FMBR Pilot demonstrated 77% less energy consumption, 65% less biosolids volume requiring offsite disposal, and 75% less footprint, compared to the legacy sequence batch reactor (SBR) wastewater treatment system that it replaced.

How is the FMBR unique?

Simultaneous SND & BioP in One Step – The FMBR conducts biological phosphorus removal (BioP) and simultaneous nitrification/ denitrification (SND) in one process step, removing C, N, and P in a low DO condition (<0.5 mg/L). This saves significant energy and footprint. Traditional wastewater treatment normally requires multiple process steps and a higher DO concentration (>1.0 mg/L). Other MBR’s are capable of SND, however, completing BioP in the same reactor is novel.

Greater Decomposition of Organic Waste – This is accomplished by facilitating a higher than normal concentration of facultative heterotrophic bacteria that decompose organic matter. A higher concentration of this bacteria is achieved by maintaining a higher than normal activated sludge concentration in the FMBR reactor.

Significantly Less Biosolids Requiring Offsite Disposal – Many anaerobic or facultative anaerobic bacteria with low productive rate coefficients are enriched in the facultative environment. The sludge loading of the FMBR system is low and the sludge age is long. As a result, BNR microbes largely rely on endogenous respiration. The benefit is a very small production of biosolids requiring offsite disposal.

FMBR DNA Benchmarking Analysis

Microbe Detectives conducted a DNA sequencing benchmarking study confirming simultaneous removal of C, N, and P, in a single tank. This study was supported by Arifur Rahman, PhD, PE, of Jacobs Engineering, and Alison Ling, PhD, PE, of BARR Engineering.
