BLU|BOX steel tank systems deliver fast, configurable MBR capacity using standardized components and proven process designs.
BLU|BOX units are pre-built, factory-tested, skid-mounted steel MBR systems, complete with every process component included. Pumps, blowers, valves, instrumentation, membrane equipment, integrated controls. Nothing left to source, coordinate, or integrate separately.
Available for flows from 25,000 gpd to 500,000 gpd, each unit is built on a universal structural frame, a standardized platform that accepts your choice of membrane type, tank material, treatment configuration, disinfection method, and seismic design. One frame. Infinite right-fit configurations.
Built-to-stock units ship in 4 to 6 weeks. Made-to-order and engineered-to-order builds address project-specific requirements without starting from scratch.

By the end of this year, we will have built a combined 38 BLU|BOX-75 and BLU|BOX-100 Units. Over the last 20 years, in total, we’ve built, designed, or are in the process of manufacturing nearly 200 MBR package plants. Some recent examples of successful projects are shown below.

Title 22 Reuse
If I had no water to drink,
I would drink our effluent water.
Taos Ski Valley, NM · 0.44 MGD · Operational 2019
No other membrane I’ve observed could handle the flow rates we did without severe permeability issues. We were very impressed. We wouldn’t go anywhere else in terms of service.

MMBR has been a trusted partner for MBR solutions for many years, consistently providing outstanding solutions for multiple projects. An invaluable resource for our team.
TSG Water · Multiple Projects
The MMBR team was great to work with from design, through delivery, startup and long-term support.
Calverton, NY · 0.1 MGD
These guys really know MBR technology. We’re very happy with the membrane modules and with the technical support from MMBR.
Willistown Woods, PA · 0.21 MGD
Ever since MMBR got involved, our MBR is working well. We’re completely satisfied. The team has been there for us when we need them.

When design-build schedules have no room for custom fabrication delays. Built-to-stock BLU|BOX units ship in 4 to 6 weeks and arrive ready to commission.
Add modules as flow grows. No overbuilding, no stranded capital, no new project every time demand increases. The platform scales with you.
Onboard membrane thickening reduces solids volume at the source. Fewer trucks, lower OpEx, less operational risk, before waste ever leaves the site.
BABA compliant and documented. Opens SRF, USDA, and other federal funding pathways that non-compliant suppliers can’t access.
Title 22, low nutrient limits, strict permit requirements. MBR delivers effluent quality no conventional system can match. BLU|BOX delivers it fast.
Modular acquisition, phased capital, reduced hauling, energy-efficient MBR process, and 20+ years of operator-centric support combine in ways no stick-built plant can replicate.
