How does MBBR wastewater treatment work?
How does MBBR wastewater treatment work?
The MBBR process utilizes floating High Capacity MicroOrganism BioChips media within the aeration and anoxic tanks. The microorganisms consume organic material. The media provides increased surface area for the biological microorganisms to attach and grow.
What does MBBR mean?
Moving bed biofilm reactor (MBBR) is a type of wastewater treatment process that was first invented by Prof. Hallvard Ødegaard at Norwegian University of Science and Technology in the late 1980s. It was commercialized by Kaldnes Miljöteknologi (now called AnoxKaldnes and owned by Veolia Water Technologies).
How is Mbbr media calculated?
Single Stage BOD Removal MBBR Process Design Calculations Using design values for wastewater flow rate and BOD concentration entering the MBBR tank, the loading rate in g BOD/day can be calculated. Then dividing BOD loading rate in g/day by the SALR in g/m2/day gives the required carrier surface area in m2.
What does BOD measure in wastewater treatment?
BOD is a measure of the amount of oxygen required to remove waste organic matter from water in the process of decomposition by aerobic bacteria (those bacteria that live only in an environment containing oxygen).
Is MBBR activated sludge?
The MBBR system consists of an activated sludge aeration system where the sludge is collected on recycled plastic carriers. These carriers have an internal large surface for optimal contact water, air and bacteria. The bacteria/activated sludge grow on the internal surface of the carriers.
How do you create MBBR?
What is SALR in Mbbr?
In either case the key design parameter for sizing the MBBR tank is the surface area loading rate (SALR), typically with units of g/m2/day, that is g/day of BOD coming into the MBBR tank per m2 of carrier surface area.
How do you calculate capacity at STP?
Multiply your Minimum Population (P) by 150 to get your daily estimated wastewater production. For example, a three bed house with a Minimum Population (P) of 5 people would have a daily estimated wastewater production of 750 litres per day (5 x 150).
