MBBR Sewage Treatment Plant

MBBR Sewage Treatment Plant

The MBBR (Moving Bed Biofilm Reactor) Sewage Treatment Plant uses specially designed plastic media inside the biological treatment tank. Microorganisms grow on the surface of the media and break down organic pollutants in the wastewater.

Air supplied through the aeration system keeps the media moving and provides the oxygen required for biological treatment. This allows a high concentration of active microorganisms to be maintained within the treatment tank while keeping the system relatively compact.

MBBR systems can be designed for villas, residential buildings, labor camps, hotels, commercial properties and other domestic wastewater applications.

🔑 Key Features & Benefits

1. Moving Bed Biofilm Technology – Uses carrier media to support biological microorganisms.
2. Compact Biological Treatment – Provides efficient biological treatment within a relatively small tank volume.
3. High Surface Area Media – Plastic carrier media provides a large surface area for biofilm growth.
4. Continuous Aeration – Fine or coarse bubble aeration supplies oxygen and keeps the media moving.
5. Low Sludge Production – Biological operation can reduce excess sludge compared with some conventional processes.
6. Flexible Capacity – Systems can be designed for different wastewater flows.
7. Easy Process Operation – No return activated sludge system is normally required for the MBBR stage.
8. Suitable for Upgrades – MBBR technology can also be used to increase the treatment capacity of existing plants.

⚙️ Process Flow

1. Inlet Screening – Removes large solids and debris.
2. Equalization Tank – Balances wastewater flow and loading.
3. MBBR Biological Tank – Carrier media supports microorganisms that biologically remove organic matter.
4. Aeration System – Blowers and diffusers provide the required oxygen.
5. Secondary Clarifier – Separates biological solids from the treated water.
6. Filtration – Additional sand or multimedia filtration can be provided where required.
7. Disinfection – Chlorine, UV or another suitable system is used before reuse or discharge.
8. Treated Water Storage – Treated water is collected for discharge or reuse.
