| Moving Bed Bio Reactor (MBBR):- |
 |
|
| |
|
| |
| Introduction:- |
|
|
| |
| Wastewater treatment plants of a medium or small scale require a simple equipment composition and easy maintenance. The Moving-Bed type bioreactor has largely simplified the washing mechanism by washing filtering media parallel to the reactor processing. |
| |
| Basic Structure :- |
|
|
| |
The Shivam MBBR is a variant of submerged aerated filter technology. It provides a small footprint solution for carbonaceous, nitrification, C+N or in anoxic mode for de-nitrification treatment with very low capital and operating costs together with a low head loss.
The MBBR can be designed as a small footprint process solution for a new works, or as a retro-fit to an existing activated sludge plant to increase capacity and improve effluent quality. It can also be operated in applications of high ammonia concentration – such as sludge liquor treatment or leachate treatment - with the continuously moving bed format in order to provide the oxygenation required for the higher load. |

Working Principle:- |
|
|
| |
MBBR is a combination of attached growth as well as suspended growth which easily degrade the organic matter present in waste water. |

Applications:- |
|
|
| |
- Municipal & Domestic Sewage Treatment
- Industrial Wastewater Effluents including
- Abattoirs
- Breweries
- Chemical Processing
- Dairies
- Distilleries
- Food Processing
- Pharmaceuticals
- Textiles
- Landfill and Bioremediation
- Permanent wastewater treatment plants
- Mobile emergency response treatment units
- Temporary treatment during planned maintenance
- Propping up biologically overloaded works
- Leachate treatment
- Industrial waste treatment
- Pilot studies

Advantages:- |
|
|
| |
- Simplified facilities
The back washing device requires only the air-compressor for the air-lift, and not the back-washing pump, blower, or tank that was needed for the fixed bed type reactor.
- Simplified construction work
A steel reactor is manufactured at the factory to facilitate the field work, so that the construction term can be shortened.
- Flexible response to the wastewater treatment projects
- Lower Capital Cost.
- Higher BOD/ COD removal efficiency.
- Higher resistance to shock loading.
- Consistent performance.
- Lower Space/ Power Requirement.
- Quick & easy installation.
- Completely mixed and highly oxygenated discharge.
- Degradation of fats, oils and grease (FOG) .
- Non-chemical pH control.
- Protects biological secondary treatment from harmful VOCs .
- Minimal O&M requirements.
- Guaranteed system performance
- Produces high effluent qualities; tolerates variations in biological and solids loadings
- Eliminates the high headloss conditions allowing the use of deeper media beds
- Eliminates the plugging potential typically associated with BAF
- Eliminates air and water distribution problems
- No backwashes are required
- Process air blowers and low head feed pumps constitute the only major power requirement
- Minimal process monitoring is required releasing valuable operator time
- Utilizes a durable media with a long proven performance life in excess of 20 years
- No moving or serviceable parts
- Small footprint
