MBR Technology
Best Available Treatment

Approaching 2,000 MBR Systems in the U.S.

As water becomes an increasingly valuable resource, more and more projects are going to membrane bioreactor (MBR).  Data suggests that we’re approaching nearly 2,000 MBR installations in the U.S. with an estimated total capacity exceeding 2,000,000,000 gallons of wastewater per day.

Some well-established MBR advantages include smaller footprint, reuse quality effluent, exceptional biological nutrient removal capabilities, and remote operation.  Some of the lesser known benefits are becoming the main drivers to MBR.  These include the ability to repurpose/retrofit existing infrastructure and the flexibility to phase in capacity over time.In simple terms, an MBR is an activated sludge process that uses submerged membranes for solids liquid separation instead of clarifiers.  A seemingly small difference that has had a big impact on the wastewater treatment industry for the last 25 years.  Considered to be “best available technology” MBR solutions in general are now competitive with conventional alternatives and in many cases more cost effective.

MBR solutions are now considered for every type of wastewater treatment project.

Common drivers to MBR:

Lowest total cost

Small footprint

High quality effluent

Water reuse

Retrofit of older technologies

Repurposing infrastructure

Phased installation

Decentralized treatment

 

Insights

The most common project types today involve the repurposing/retrofit of old systems or phased installations that start with modular, steel package systems.
