A Moving Bed Biofilm Reactor (MBBR) is a biological treatment technology for wastewater that uses microbial biofilm formed on media “carriers” to remove organic contaminants dissolved in water.  Biofilm carriers are suspended in the wastewater flowing through the reactor and thoroughly mixed to create a protected surface to develop a biofilm community. This biofilm subsists on the organic molecules while treated wastewater leaves the system. MBBR systems are commonly used by industrial facilities due to their compact sizing and high treatment rate. They can be used to remove soluble BOD/COD and nitrogen-based contaminants (TKN, Ammonia, Nitrate/Nitrite) that are common in industrial wastewater.

The Biosphere® Mobile MBBR System by Evoqua Water Technologies, now part of Xylem, is a skid-mounted system that does not require a permanent foundation for installation. This compact system is delivered pre-assembled and rapidly commissioned.

It is an effective solution to quickly deliver MBBR capabilities on demand, avoiding the long lead times for permanent biosystem installations. Our rental MBBR systems fit a number of potential applications, including:

• Rapid replacement of failed equipment
• Providing a bridge solution during permanent system construction, retrofits or maintenance turnarounds
• Meeting pretreatment discharge limits
• Soluble BOD/COD removal
• Biological nutrient removal
• Piloting: partial and full scale

In addition to BOD/COD these units can also be used for Ammonia treatment (NH3/TKN) and can be configured for nitrates removal (NO3/NO2) as well.

Our Biosphere Mobile MBBR System consists of three primary components: the mobile bioreactor, aeration blower, and the system control skid. The chart illustrates the potential treatment capacity of a single mobile MBBR across several different industries. Multiple mobile units can be systematized in parallel or series configurations to treat additional wastewater capacity or to meet different treatment goals.
