2025 PROJECT OVERVIEW

Project Category : Retrofit

Previous Membrane : BIO-CEL 416 (Flat Sheet, Polymeric)

Installed Membrane : BIO-CEL L+ (Flat Sheet, Polymeric)

Status : Operational

DESCRIPTION

M|MBR helped deliver the Yakama Nation tribal WWTP in 2008. When the original MBR system needed more capacity, M|MBR upgraded the plant in 2017 from rigid-plate Kubota ES-200 SMU membranes to flexible flat-sheet BIO-CEL 416 modules, doubling capacity from 0.18 to 0.36 MGD. In 2025, after eight years of successful operation, M|MBR supported a second backward-compatible upgrade to BIO-CEL L+ for added performance and safety margin.

The part-for-part replacement was coordinated with plant operators and took approximately 24 hours of scheduled, phased downtime.

The project highlights M|MBR’s ability to extend plant life and solve capacity constraints with practical aftermarket solutions.

The MMBR team has provided excellent support from the original design of this plant and through the expansion. They are knowledgeable, responsive, and great partners.
