The MBBR System is the latest advance in attached growth aerobic biological treatment technology. MBBR employs RING PAC MEDIA neutrally buoyant bio-film carrier elements to achieve outstanding BOD/COD removal productivity from a compact bioreactor. In MBBR the liquid to be treated is pumped through a bed of small media at a sufficient velocity to cause fluidization. In the fluidized state the media provide a large specific surface for attached biological growth and allow biomass concentration to develop.

Features:

• Robust construction
• Wide application
• Long operational life
• Cost efficient

The Sequencing Batch Reactor process (abbreviated SBR procedure) is a variation of the conventional activated sludge process. The SBR consists of a reaction chamber which first operates as a biological reactor and then as sedimentation chamber. Unlike reactors where the wastewater flows through continuously, the SBR is filled and emptied discontinuously. The conventional physical separation of the biological processes and the sedimentation is replaced by a chronological one. The cycle starts with the filling phase where the first decomposition processes start under anaerobic or anoxic conditions. In the actual decomposition or reaction phase, the reactor is ventilated. Depending on the cleaning target, unventilated phases can be projected as well. Afterwards, in the sedimentation phase, the activated sludge sediments and the Clear water layer develop. The supernatant Clear water is removed in the sedimentation phase. Then, the cycle starts from the beginning. A separate secondary sedimentation is not required in the SBR process.

Features:

• Filling phase (biology reactor)
• Cleaning phase
• Sedimentation phase (60 min.)
• Clear water removal phase

Municipal Sewage Treatment Plant
This means that the main treatment processes are geared towards organic removal. In a typical treatment plant, the wastewater is directed through a series of physical, chemical and biological processes each with specific waste load reduction task. The tasks are typically.

• Pre-treatment: Physical and / or chemical /( influent flow measurement, screening (Bar racks), Shredders, comminutors (macerators), pumping, grit removal)
• Primary treatment: Physical / (sedimentation)
• Secondary treatment: Biological / (biofiltration or activated sludge)
• Advanced treatment: Physical and / or chemical and / or biological.
• Tertiary treatment (Followed by series of filtration process)
• Sludge treatment (anaerobic digestion of the sludge produced in primary and biological treatment)
