IMPORTANCE OF THE MEDIA
THE HEART OF MBBR TECHNOLOGY
Utilizing a non-clogging carrier with high active surface area is a key for successful MBBR system. Aquatech uses a high speed carrier media that offers several advantages over other MBBR media available in the market.
Space Savings: Smaller foot print - Due to higher active surface area; BioCORE™ requires less media volume and therefore less reactor volume. As a result, the associated tank construction is smaller compared to other processes and thus cost saving in overall capital expenditure.
Active Surface of New and Used MBBR Media: Most MBBR suppliers in the market claim to have MBBR media with specific active surface area in the range of 500 to 700 m2/m3. However, after operation of a year or so, due to clogging of the media by uncontrolled growth of biofilm, the active surface area in the media is reduced to less than 50%, adversely affecting the plant performance. BioCORE™ media has five to six times’ higher active surface area (3000 m2/m3) than competing MBBR media available in the market. The parabolic disc shape of BioCORE™ media enables the hydraulic shear forces acting on the media surface to create a constant renewal of biofilm on the media active surface resulting in steady, uniform biofilm thickness and there is no loss of active surface area even after years in operation.
Geometry of Media: Easy to fluidize - The special parabolic disc type geometry of BioCORE™ helps with uniform distribution and mixing-in of media in the bioreactor. other MBBR medias have irregular biofilm growth and do not distribute uniformly in the bioreactor which affects performance.
Less Media Volume: More active surface area - BioCORE™ offers several folds higher active surface area than most of the other well-known MBBR media available in the market. As a result, it is expected that BioCORE™ media volume proposed for a given project is less than the media volume proposed by the competition., based on the assumption that the specified COD reduction in the inquiry is achievable with MBBR system.
Power Savings: Less power consumption - The special geometry of BioCORE™ requires less aeration (mixing energy) to keep the media in suspension. The overall power consumption for BioCORE™ based MBBR system is lower than the competition.

AN ADVANCED BIOLOGICAL PROCESS
BioCORE™ Advanced Moving Bed Bioreactor (MBBR) is specifically
designed to process difficult to treat industrial wastewater. MBBR is
well-known as one of the most robust bio technologies and is widely
used for processing difficult to treat wastewater applications in
refineries, petrochemicals, pulp and paper, steel, and other industries.
BioCORE™ provides effective treatment of high-strength wastewater
while achieving a consistent effluent quality that complies with
increasingly stringent environmental regulations. The unique design
optimizes the contact between the biomass and the wastewater, thus
improving, on the one hand, the tolerance to variability in organic load
and, on the other hand, the compactness of the system.
BIOCORE™ APPLICATION
BioCORE™ delivers performance to industries and infrastructure
through immobilization of microorganisms in high end biological
wastewater treatment systems fot the removal of a broad spectrum of
contaminants, to include the following:
• Biodegradable Organics (BOD)
• Nitrogen Compounds (TKN or NH3)
• Phosphate Removal (as nutrient)
• Specific metals (Selenium and Arsenic)
VALUE PROPOSITIONS
BioCORE™ is:
• Compact - Smaller Space
• Optimized Surface - Media geometry
• Robust - Withstanding variability in Feedwater
• Efficient - Lower Opex and Capex
Lower OPEX
• Lower mixing energy (disposal sludge,
downtime, new seeding period)
• Lower sludge generation
Lower CAPEX
• Civil cost impact: from 50% to 40% volume
saving in tanks and/or buildings
• Installation cost (less rotating equipment)
and overall equipment savings

CORE BIOLOGICAL TREATMENT
Efficiency, consistent effluent quality and ability to withstand the feedwater variations with minimal impact are key
aspects in a biological process. BioCORE™ technology has inherent features that meet all the above stated criteria.
