Facultative Membrane Bioreactor for Wastewater Treatment
The Facultative Membrane Bioreactor for wastewater treatment (FMBR) provides a compact, automated, decentralized solution, suitable for treating municipal, food, and other wastewater with a high percentage organic matter. As compared to traditional wastewater treatment processes, the FMBR reduces energy consumption by 30%+, footprint by 50%+, and residual biosolids by 70%+. As a DEWATS solution, 99%+ of wastewater flow can be recovered and reused onsite as clean water effluent, offering a significant water conservation opportunity and a reduction in water security risk.

How does the facultative membrane bioreactor for wastewater treatment work?
How does the FMBR remove Carbon (C)?
The Facultative Membrane Bioreactor for wastewater treatment is designed to decompose organic matter to a greater degree than traditional MBR or SBR wastewater treatment processes. 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.
How does the FMBR remove Nitrogen (N)?
The Facultative Membrane Bioreactor for wastewater treatment completes nitrification/denitrification in one step, simultaneously, in a low dissolved oxygen (DO) condition (<0.5 mg/L). The nitrification-denitrification process is enhanced by encouraging a facultative environment and maintaining a high activated sludge concentration. A facultative environment is encouraged by carefully controlling DO, the gradient of DO distribution, and the liquid flow regime in specialized control schemes that are designed to optimize nitrogen removal. Over the 12 month Pilot Demo during 2020, total Nitrogen levels were reduced from an average 62.7 mg TN/L in the influent to 4.1 mg TN/L in the effluent.
How does the FMBR remove Phosphorus (P)?
By decomposing organic matter to a greater degree than normal, the Facultative Membrane Bioreactor for wastewater treatment is designed to generate a greater amount of VFAs. This means more food for PAOs. The unique operating characteristics of the FMBR are designed to enable BioP in the same single reactor where SND occurs, when the proportion of each component in the influent is appropriate. Over the 12 month Plymouth Pilot Demo during 2020, Phosphorus levels were reduced from an average 10.0 mg P/L in the influent to <1.0 mg P/L in effluent. View the Pilot Study report here.
What are the typical effluent parameters achieved by FMBR technology?
For the typical municipal wastewater, our effluent can reach BOD5≤30mg, TN≤10mg/L, TSS≤10mg/L.
How do you handle the residual sludge? Can your sludge go to digestion before it goes to a landfill?
- Compared with the traditional process, our sludge yield is much less. Our sludge age is longer and basically digested more thoroughly.
- Generally, press filtration can be carried out first, and then landfill or resource treatment can be selected according to local requirements.
If we want to retrofit the existing system, e.g. sequencing batch reactors (SBR) tank, is this something JDL can support?
We generally provide integrated, complete process packages. We welcome retrofit opportunities.
FMBR Pricing and Pilot Demos
What is its price per MGD flow?
The price depends on the project scale, the equipment is just a carrier of our technology. We will design the system according to the actual project situation to guarantee the effluent quality, and of course, we will reduce as much cost as possible for the clients. And to release the financial pressure of our clients, we do BOT, BOOT, EPC and equipment rental mode, and provide zero-interest rate.
What's the cost for the 2,500 GPD to the 25,000 GPD modules, by cost/GPD?
Depending on the design capacity, influent characteristics and effluent criteria, and location, the difference will be relatively large. Under the same scale and the same influent and effluent conditions, Facultative Membrane Bioreactor for wastewater treatment will have cost advantages, but the capital reduction must be analyzed by specific projects. Under normal circumstances, the price of a factory-built steel Facultative Membrane Bioreactor for wastewater treatment is about $5,000-$10,000 US dollars per average daily tons of wastewater treated.
Can you provide pilot equipment for rental? Do you have some requirements?
We can provide various methods such as equipment leasing or investment, and there are no specific requirements. We can negotiate the detail on the specific project.
Do you have any time schedule for a demonstration pilot?
Pilots are usually 3 to 6 months. You can refer to our pilot plan.
