MBBR Is An Improved Version Of Fixed Film Bio Reactor Like SAFF (Surface Area Fixed Filmed Technology (SAFF) Or Rotating Bio Reactor (RBC), With A Difference Of MBBR Carrier Media Is Free Floating In The Sewage/Effluent. MBBR Technology Employs Thousands Of Polyethylene Biofilm Carriers Operating In Mixed Motion Within An Aerated Wastewater Treatment Basin.
A Moving Bed Biofilm MBBR Reactor Consists Of A Tank With Submerged But Floating Plastic (usually HDPE, Polyethylene Or Polypropylene) Media Having Specific Gravity Less Than 1.0. The Large Surface Area Of The Plastics Provides Abundant Surface For Bacterial Growth. Biomass Grows On The Surface As A Thin Film Whose Thickness Usually Varies Between 50-300 Microns. Each Individual Bio Carrier Increases Productivity Through Providing Protected Surface Area To Support The Growth Of Heterotrophic And Autotrophic Bacteria Within Its Cells. It Is This High-density Population Of Bacteria That Achieves High-rate Biodegradation Within The System, While Also Offering Process Reliability And Ease Of Operation. Medium Or Coarse Bubble Diffusers Uniformly Placed At The Bottom Of The Reactor Maintains A Dissolved Oxygen (DO) Concentration Of > 2.5-3 Mg/L For BOD Removal. Still Higher DO Concentrations Are Maintained For Nitrification. To Retain The Media Flowing Out Of The Tank, Screens Are Placed On The Downstream Walls. A Clarifier Or A DAF Is Placed Downstream Of The MBBR Tank To Separate The Biomass And The Solids From The wastewater. No Sludge Recycling Is Required For This Process.
MBBR Media Used In Wastewater Treatment
Aeration Tank: The Tank Is Similar To An Activated Sludge Tank. The Aeration Is Used To Keep In Motion The Activated Sludge And Carriers. The MBBR System Separates The Excess Bacteria And Sludge Which Are Directed To The Final Separator.
Special Plastic Carriers: They Provide A Surface For Biofilm Growth. Carrier Materials Are Made Of Materials With A Density Close To That Of Water (1g/cm3) An Example Is High-density Polyethylene (HDPE) With A Density Of 0.9g/cm3. These Carriers Are Moved In The Tank Through The Aeration System. This Ensures Good Contact Between The Wastewater And The Biomass On The Carriers.

MBBR Technology
Ideally, The MBBR Process Is Known To Improve Reliability, Simplify The Operation And Process Not To Mention The Fact That It Requires A Smaller Storage Space Compared To Traditional Sewage Treatment Plants. For This Reason, There Is A Well-managed Technology Behind The MBBR Process To Help Ensure This Becomes Possible.
The Technology Involved During The MBBR Process Uses Thousands Of Polyethylene Biofilm Carriers. These Carriers Operate Within An Aerated Mixed Wastewater Treatment Basin In A Combined Motion.
Each Carrier Provides A Protected Carrier Which Helps In The Growth Of Autotrophic And Heterotrophic Bacteria Within The Cells. This Technology Helps Increase Productivity And Effectiveness Of The Process.
The High Population Of Bacteria Helps Achieve High-rate Biodegradation Within The System And Also Provides Ease Of Operation, Not To Mention The Reliability Of The Process.
The MBBR Process Also Has An Optimum Level Of Productive Biofilm Which Makes The Process And The Technology Cost-effective And Easy To Maintain. There Is Also The Biofilm Which Is Attached To The Mobile Carriers Found Within The System Which Automatically Responds To Load Fluctuations.
Like In Any Other Situation, The MBBR Technology Has Both Its Bright Sides And The Dark Sides Too. For Instance, One Of The Most Significant Advantages Of MBBR Technology Is That It Can Be Used In Already Existing Tanks.
This Means That You Do Not Need New Tanks When You Intend To Introduce The MBBR Process In Your Home Or Institution. All You Have To Do Is To Call Us When You Need The MBBR System, And We Shall Help You Achieve Your Goal With What You Already Have.
However, The MBBR Technology Also Has Its Negative Side. For Instance, You Will Need To Have Basic Sewage Plants For You To Be In A Position To Operate And Coordinate MBBR Sewage Water Treatment.
MBBR Working Principle
After Successfully Installing The MBBR System, You Need To Understand Its Working Principle For You To Get The Best Out Of It. Luckily, The MBBR System Has A Simple Working Principle That Anyone Can Easily Understand.
For One The MBBR System Has Activated Sludge Aeration Systems In Which Case The Sludge Is Collected On The Recycled Plastic Carriers. These Carriers Named K1 Media Have A Large Surface For Air, Bacteria And Contact Water.
The Activated Sludge, Which Is Also Bacteria, Grows On The Internal Surface Of The Carriers. This Way, Organic Matter From The Wastewater Is Broken Down By The Bacteria.
The Excess Sludge With Then Come Separate From The Carriers And Will Then Flow With The Treated Water Towards The Final Separator.
This Will Also Help Eliminate The Extra Amount Of Bacteria Growth.
Additionally, Depending On The Specific Demands, The System Can Have One Stage Or More Stage System. The Primary Bacteria Of The Process Remain In Their Own Duty Tank Since The Carriers Remain Only In One Tank.
Screens Usually Protect This Tank.
Depending On The Discharge Regulations And Quality Of The Wastewater, The MBBR Process Can Be Used For Different Applications To Help Give The Desired Results. Some Of The Standard Industrial Applications Of The MBBR System Include:
- Fast Recovery From Process Upsets
- Limited Footprint
- Capacity Increase
- Quality Improvement – Nitrogen And BOD Removal
- Minimize Operator Attention And Process Complexity
- Future Expansion
Additionally, There Are Also Several Benefits That You Enjoy Through The Use Of The MBBR Process. Some Of These Include:
- Maintenance Friendly
- Simple To Extend
- Financial Saving On Discharge Costs
- High Volume Load
- Economically Attractive
- Compact; That Is Saved On The Space That Is Used In For Its Storage
The Characteristic Of The Biofilm Establishing On The Carrier Surface Is Not Only Influenced By The Composition And Loads Of The Pollutants In The Wastewater (substrate) But Also By The Shear Forces In The Tank. This Helps Ensure That The MBBR Process Has Constant Biological Removal Rates And Reliable Process Stability.
MBBR Process
A Sensitive Factor In The (MBBR) Process Is The Adequate And Frequent Contact Between The Microorganisms Attached To The Carrier And Biofilm Wastewater Components. The Aerobic Treatment Process Can Be Used To Achieve The Necessary Mixing Of The Carrier Elements In The Reaction Tank.
The Quality And Characteristics Of The Biofilm Which Is Seen On The Carrier Surface Are Influenced By Not Only Shear Forces In The Tank But Also By The Loads And Components Of The Pollutants In The Wastewater (substrate). The Quicker And The More Intense The Growth Of Biomass, More The Wastewater Is Polluted With Biodegradable Contaminants,
Easy To Install. Their Installation Procedure Is Not Complicated.
The Carriers Which Are Found In The Reaction Tank Can Be Appropriately Moved By Pumping Water Through An Anaerobic Treatment Process Or By Using Immersed Slowly-rotating Mixers.
Consequently, They Will Be Thin Since They Are Protected From The Shear Forces From Inside The Pores. It Is Essential, However, To Remember That The Oxygen Required For The Aerobic Biodegradation Processes As Well As The Thin Biofilms Are Crucial For An Optimal Supply Of The Microorganisms With Substrates (removable Pollutants And Nutrients).
Problems Caused By A Reduction In Biodegradation Efficiency Are Mainly Due To The Thickness Of The Biofilms, Which Result In A Reduction Of The Active Carrier Surface Area. Luckily, This Issue Is Not Present In The MBBR Biochip 25.
Its Process Also Differs In That The Biofilms, Which Try To Grow Out Of The Pores And Colonize The Pores Of The Biochip, Are Ensured That They Remain Thin By The Shear Forces. For This Reason, The MBBR Biochip Allows For Consistently High Biological Removal Rates And Reliable Process Stability.
