What is the technology?

We call it MagnaTree

It's a reimagined membrane bioreactor (MBR) - ours uses biofilms developed on coarse meshes, i.e., "dynamic membranes" 

It's also a new-style of hybrid bioreactor - much of the biological treatment can happen in the biofilms, which are entirely active!

Why is this meaningful?

The mesh is much less susceptible to severe fouling than conventional MF/UF membranes - this means no chemical cleans or sparging! Little to no operator intervention is required!

Unlike conventional biofilm systems, this isn't diffusion-limited.

How do costs compare?

OPEX: 25 - 50% reduction relative to MBR

CAPEX: 50+% reduction relative to MBR

What is the current status?

Bench-scale validation of:

  • 400+ days of low-pressure filtration of wastewater w/ order(s) of magnitude lower fouling rate than MBR. ref

  • 100s of days of filtration of food waste and sludge without employing membrane cleaning.

Pilot-scale system

  • Deployment at the Ann Arbor WRRF starting Fall '23
