Moving Bed Biofilm Reactor (MBBR) Wastewater Treatment Systems

A moving bed bioreactor (MBBR) with a smart design can provide better cost effectiveness than membrane bioreactor or activated sludge plants. MBBR process design services from SSI Aeration help wastewater treatment plants improve their efficiency. SSI’s MBBR systems save money in plant construction, operation and maintenance.


SSI Aeration’s MBBR offers advantages only found in our MBBR process design services. MBBR engineers at SSI focus on minimizing the following:

Additionally, SSI MBBRs increase factors such as:

SSI’s MBBR systems increase performance and cost-effectiveness through smart design principles.

Service Advantages

When wastewater treatment facilities work with SSI on MBBR wastewater systems, they gain the following benefits:

  1. In-house media creation: SSI engineers and fabricates its own media to exacting specifications and superior quality.
  2. In-house diffuser creation: SSI also engineers and fabricates its own diffusers to ensure maximum quality and performance.
  3. Superior media and diffuser interface: SSI specifically designs its media to work with its diffusers. Working with SSI helps ensure complete compatibility between diffusers and media for the most streamlined operations.
  4. Industry-specific experience: SSI has dozens of years of experience designing and building MBBRs for a multitude of industries, including the food, textile, and petroleum-processing industries, as well as the pulp-and-paper manufacturing and chemicals manufacturing industries.
  5. Multidisciplinary expertise: SSI is one of the only companies where clients will find expertise in diffuser manufacturing, media manufacturing, and MBBR design all under the same roof. This unmatched array of knowledge allows SSI teams to work together with multidisciplinary approaches to give clients the best experience possible.
  6. Practical, experience-based solutions: The practical benefits of SSI’s multidisciplinary expertise are numerous. SSI has studied which resins to use to produce media, so they mix with the least expenditure of energy. SSI has determined which diffuser size and coatings work best to minimize maintenance. Plus, SSI knows what problems plants could encounter with their MBBRs — such as overflows from failed retention screens — and can take precautions to prevent these issues before they occur.
  7. Robust R&D program: SSI has a strong research and design program that is active in pursuing new methods and designs for media production and MBBR system installation. The R&D team is also engaged in analyzing and engineering for the interactions between media and diffusers in MBBR systems.
  8. Library of SOTE resources: SSI also has an immense library of resources for standard oxygen transfer (SOTE) testing. We can apply these resources to help optimize MBBR system design and performance in terms of oxygen transfer.
  9. IFAS experience: SSI has extensive experience with integrated fixed-film activated sludge (IFAS), which requires less volume than conventional activated sludge systems, requires less maintenance and involves fewer capital costs. We can supply these systems with fixed media and have expertise in operating them.
  10. Superior, clean IFAS systems: SSI’s IFAS systems are some of the best — and best-maintained — in the industry because we can keep them free from undesirable organisms like flies, leeches and slugs. Being proactive in this way helps keep MBBR systems running efficiently.


EEVolved MBBR for Biological Treatment

The EEVolved MBBR from SSI Aeration provides unparalleled results. This proprietary technology involves an innovative biofilm technology for biological treatment. SSI engineers designed the EEVolved MBBR with an advanced understanding of hydrodynamics, aeration integration, and biofilm. As a result, clients receive a treatment process focused on efficiency and safety. EEVolved MBBR systems have the most effective and secure treatment processes available.

Low Hydraulic Retention Time (HRT)

MBRs have the lowest hydraulic retention time (HRT) among biological wastewater treatment processes. This low HRT rate results in smaller reactor sizes that offer better volumetric efficiency than processes such as MBR. The SSI Aeration team combines expertise in aeration with knowledge about fixed film technology to develop these systems.
