THE MBBR CONCEPT
MBBR ( Moving Bed Bio Reactor) waste water treatment plant can be described as a confined space in which the organic digestive microorganisms get attached to specially designed plastic media called AGM ( Attached Growth Media) . The AGM Bio Media become carriers that build floating bed in the waste water. The Bio-Film grows on the bio media surface and moves along with the water inside the reactor chamber creating what we call the biomass, the efficiency of this biomass in reducing the organic load in waste water is behinde the success of MBBR system.
Once submerged inside the bioreactor, the AGM Bio Media operates as non-clogging media. No channels or dead spots like in other technologies. The movement is caused by efficient aeration, system well designed according to the effluent requirements. The AGM Bio Media optimizes growth (biomass), and provides shelter and protection for the biomass and makes the WWTP extremely robust and reliable.
AGM BIO MEDIA
The AGM Bio Media has proven to be superior to any known bio media and can handle pH variation, shock loading, temperature variations, and drastically reduce the size of a WWTP.
AGM Bio Media Can be utilized in New or Old Bio Reactors and Enhance Performance. Once the bio media is placed inside a Bio Reactor and set in proper operation, you have a compact stabile, clog-free biofilm reactor. If your goal is to build the Best WWTP possible, agreeable with your budget, then you should carefully consider the AGM Bio Media Technology and let us discuss how we can help you.

What IS AQUA SMART® MBBR SYSTEM ?
AQUA SMART® is a compact WWTP that produces a very high quality effluent water suitable to use in field irrigation, industrial use, wash-water, flush water, industry etc. The prefabricated AQUA SMART® MBBR compact systems are completely autonomous and provide a very high level of treatment.

THE MAIN ADVANTAGES OF AQUA SMART® SYSTEM
THE BASICS OF THE WASTE WATER TREATMENT SYSTEM
Though all the above mentioned equipments are important for the system , our company always gives
extra attention to the following components
- The Bio reactor tanks
- The Bio Media
- The Belt Press
- The PLC Program
1. THE MBBR BIO REACTOR TANKS
|The containers we produce have waste water treatment capacity from 25m3- 400m3/ day. 6mm thick steel that is used in the ship industry is always used in our tanks; our carful engineering calculation helps us secures the minimum welding joints in the tank structure. We are capable of manufacturing 12 M long joint less tank. The internaland the external tank surfaces are protected against corrosion with very high quality epoxy paint. The tank is divided into three separate chambers; the volume of each chamber is carefully calculated to secure themaximum efficiency in water treatment..|
|The AQUA SMART® MBBR tanks are unique in their design, though they are fully covered, the carbon dioxide gas’ build up in the tank is prevented, a double purpose perforated steel strip is fitted on the tank’s roof to serve as a walk way and as a carbon dioxide relief opening. The remaining part of the tank’s roof is covered by 1.2 mm thick steel sheets 750mmx 950 mm in size hinged to the tank’s body and can be lifted separately for spot inspection.|
2. THE BIO MEDIA
- AQUA SMART® BIOMEDIA secures 10 Times Loading in 20% of the Hydraulic Retention Time required .
- AQUA SMART® BIOMEDIA secures 950 m2/m3 Surface Area inside the System
- AQUA SMART® MEDIA offers Clog Free and Self Cleaning operation
- Bio Film Grows on the AQUA SMART® Mediaand Offers Sheltered & Robust Operation
- No Backwash Required,
- Mess Free Operationwith minimumservicerequirements
|Our tank is divided into three separated chambers , the amount of BIO MEDIA added to each chamber is calculated and introduced accordingly ,the waste water’s BOD values are gradually reduced as the waste water passes from one chamber to the next , a BOD value of 20 mg/L is always attainable by this process, BOD values of 10 mg/ L or even less are also achieved by circulating back part of the effluent water to the tank’s first chamber .|
3. THE BELT PRESS
|To dewater the sludge we always use belt press instead of filter press or decanter. In countries where energy is scarce the belt press is a must since it consumes much less electricity than the decanter , as far as the filter press is concerned though it is cheaper as an investment ,it coasts double in manpower since it is manually operated ,thus on the long run the most economical dewatering system is the Belt Press.|
4. PLC PROGRAM
|AQUA SMART® offers a state of the art automation and control solution for the MBBR waste water treatment process. Since each plant is built for certain purpose the PLC program and the control panels provided are always tailor made to suit the plant erected. The PLC program and the panel design is made in our company and before the automation system is executed it is always checked and approved by a senior PLC engineer in Siemens AG.|
