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.

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 IFAS, 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.

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.

Media Screens

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.

Fixed grid aeration

Thanks to the integration of Nexom and 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.

BOD and AMMONIA ARE NO MATCH FOR BIOPORTS

The BioPorts™ process is the best choice for roughing high influent BOD, polishing ammonia, or upgrading to IFAS. In place at dozens of installations across North America, BioPorts MBBRs or IFAS installations deliver as promised and ensure that operators sleep well at night knowing they have the system in place to beat their BOD and nutrient limits.
