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: 25 - 40% 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
-
Under construction for Fall/Winter '22 deployment
