A Modern Alternative for Wastewater Treatment

The Facultative Membrane Bio-Reactor (FMBR) is a compact, decentralized wastewater treatment system with a small footprint, low energy consumption, minimal residual biosolids, and a reliable, high qualify effluent water. Proven in over 3,000 installations in 19 countries as a sustainable wastewater solution.

Decentralized Wastewater Treatment System in a Single Bio-Reactor

The FMBR is a decentralized wastewater treatment system for small to medium size communities, commercial developments, and food operations. The FMBR uniquely completes wastewater treatment with naturally selected microbes in one automated step, saving energy and biosolids, while recovering 99% of wastewater as clean water.

The FMBR is available in portable, factory-built, steel bio-reactor modules and custom engineered concrete bio-reactors. Both can be containerized, installed underground or in a building, with no odor. Portable modules are ideal for Pilot Demonstration Projects and smaller systems with flows up to 100,000 GPD. They offer a simple, turn-key, automated, wastewater treatment solution, with fast construction, and little maintenance. Concrete FMBR bio-reactors can be custom designed by JDL to meet unique requirements, treating wastewater flow up to 34 MGD.

JDL is seeking pilot demo opportunities with facilities in need of sustainable wastewater solutions.

About the FMBR Decentralized Wastewater Treatment System

The F-MBR was invented by Jiangxi JDL Environmental Protection Co., Ltd. (JDL) of Nanchang, China in 2008 and is protected by invention patents across the USA, UK, France, Japan, China, and others. JDL recently opened its US headquarters in New York, and is working with WaterTrust to bring FMBR solutions to US markets. JDL is publicly traded on the SSE with a market cap >$1 billion and has 650+ employees.

Validated in over 3,000 installations across 19 countries, including the Plymouth Massachusetts Municipal Airport since November 2019 and by Microbe Detectives‘ independent DNA benchmarking analysis.

How does the FMBR work?

The FMBR applies specialized environmental controls to cultivate a facultative environment of beneficial microbes that coexist in a single bio-reactor and form a microbial food chain that simultaneously removes Carbon (C), Nitrogen (N), and Phosphorus. View FMBR specifications.

How is the FMBR different from other MBRs and SBRs?

Traditional sequencing batch reactors (SBR) and membrane batch reactors (MBR) perform nitrification and denitrification in two-steps with a dissolved oxygen (DO) concentration commonly greater than 1.0 mg/L and remove Phosphorus in a separate biological process (BioP). As compared to these traditional processes, the FMBR saves significant energy, footprint, and residual biosolids requiring offsite disposal. Similar to the FMBR, some MBRs save significant energy compared to traditional wastewater treatment processes by completing simultaneous nitrification–denitrification (SND) in a low DO condition. However, few (if any) modern MBRs conduct SND and BioP, in the same vessel, at the same time, at a low DO condition less than 0.5 mg/L. By conducting SND and BioP simultaneously in the same vessel, the footprint can be further reduced, and the treatment process can be further simplified and automated.
