OUR TECHNOLOGY: BIOPORTS MBBR
BioPorts™ MBBR
NEI is the exclusive source for the BioPorts™ moving bed biofilm reactor (MBBR). BioPorts combines concentrated attached-growth reaction kinetics with NEI's unmatched biological treatment expertise to create an industry leading nitrification, denitrification, and BOD removal technology.
Why do you need a BioPorts system?
BioPorts technology installed at your plant allows you to:
- Meet ammonia, BOD, total nitrogen and/or nitrate
limits
- Compact design allows your plant to do more with
the space you already have
- Coarse screens and Screen Scour™ makes
BioPorts™ a low-maintenance, simple-to-operate
solution
BioPorts MBBR media can be used in purpose-built tanks or to turn activated sludge basins into IFAS systems.
How it works
RELIABLE, SIMPLE, INTENSE.
BioPorts MBBRs work based on a series of basic principles, offering them three key advantages:
BioPorts MBBRs are reliable.
When flows increase quickly, it can overwhelm an activated sludge system’s capacity and cause biological washout.
With BioPorts, your biology is fixed where you need it: in your treatment basin, fixed to the surface of BioPorts media which themselves are retained using coarse screens. No more biology washout.
BioPorts MBBRs are simple.
Balancing return activated sludge is a challenging part of managing an activated sludge plant, and although the improvements in oxygen transfer make it well worth it, managing membrane-based or, more challenging yet, fixed-pore fine-bubble aeration adds to an operator’s workload.
With BioPorts MBBR, you don’t need to return your activated sludge because, again, your active biology is fixed directly to the media retained in the basin using coarse screens. And because moving media both impedes the rise and breaks up the aeration bubbles, lower-maintenance membrane-free diffusers can be used while achieving the same oxygen transfer.
BioPorts MBBRs are intense.
When your facility was first designed, it probably wasn’t being asked to handle the high strength or variability as you’re seeing now, and that was when it was brand new!
Create and retain the density of treatment to better handle today (and tomorrows’s) loading levels and their fluctuations, all thanks to your BioPorts MBBR.

BioPorts media retention screens are fine enough to keep the biofilm-carrying media from escaping the basin, but coarse enough to allow particulates to pass through and prevent the screen from fouling or blinding.
Media screens can also be arranged in parallel to better accommodate variable flows. Vertical screens with above-surface access ports can be used to enable better access for effluent sampling or occasional screen maintenance.

Thanks to our the integration with EDI, our aeration capabilities are the envy of the industry. Most BioPorts facilities are designed with EDI fixed grid aeration within our basins to optimize performance with minimal O&M.
In fact, based on that aeration expertise, Leeds, Alabama’s BioPorts MBBR is able to achieve optimized mixing and oxygen-transfer with ~25% of the energy typically required.

There are many factors which can influence the cost of a BioPorts system, including design flows, loading, treatment requirements, and existing infrastructure. The best way to determine the cost for your specific application is to submit your RFP to our project development team.
Based on its small footprint design and modular scalability, BioPorts is among the most simple wastewater treatment solutions to upgrade, whether your focus is further nitrification or BOD removal, denitrification to meet Total Nitrogen limits, or beyond.
Almost never. The media is sized so that it can be retained by coarse effluent screens for no downstream media loss, and it is built from durable HDPE that means the BioPorts media that you start with should last the life of your installation.
If you are looking to achieve <1 mg/L of ammonia in freezing cold water, NEI has already solved that problem with the SAGR, which has numerous proprietary advances that help it overcome limitations related to cold lagoon effluent.
BioPorts is tremendously effective in many post-lagoon settings, so to identify which solution is best for you, reach out and let our NEI process engineers guide you.
