subject: Function And Advantage Of Mbbr Media [print this page] The MBBR MEDIA/IFAS method is a revolutionary biological remedy process utilizing hundreds of specific carriers created to produce a massive total surface for biofilm growth improving your waste water remedy method without expanding your footprint. The program can be controlled as either a MBBR MEDIA or an IFAS structure.
In the MBBR MEDIA configuration offers therapy process depending on a bio-film which gives natural carbon elimination, and nitrification and de-nitrification where essential, without distribution of stimulated slop. The procedure is easy, robust, and needs minimal operator involvement. Wastewater is launched into a single or several-stage system (based on whether Nitrogen elimination is needed), all of which consists of the appropriate volume of biomass carriers.
The MBBR MEDIA settings is very appropriate for a wide range of purposes: from pre-remedy of industrial wastewater, to complete remedy of municipal wastewater to the most stringent effluent requirements, as a standalone solution or as a polishing of present remedies such as lagoons.
In the IFAS configuration makes use of the complicated relationships between a bio-film on the biomass companies and suspended biomass in the stimulated debris. This co-living generates a specialised and extremely focused nitrifying bio-film on the biomass carriers, serving concurrently with the natural carbon oxidization by the activated sludge. This process rule is to present biomass providers into the triggered sludge, thereby enabling the triggered debris to remove much of the BOD, whilst allowing the biofilm to produce a microbiological population that oxidizes ammonium substances.
The IFAS configuration is specifically well matched for retrofitting existing plants so as to include nitrification capacity, in addition to increasing carbonaceous BOD removing, without any extra tank quantity. This configuration can also be employed in freshly created plants.
Features and advantages
Economical - Lessen capital and procedure costs than traditional options.
Little Footprint - Avoids infrastructure improvement required for extra tankage.
Just-in-Time growth - The MBBR MEDIA/IFAS system allows gradual, multi-step, plant growth, by gradual addition of natural carriers.
Stable Process - Dangerous distracts and hydraulic 'wash out' occasions by no means affect the whole microbial population in the bio-film, therefore process recovery is quick and clean.
Intensive Nitrification - The MBBR MEDIA/IFAS method enables quantitative nitrification perhaps at a minimal sludge age of the triggered debris, by keeping a separate population on the biomass carriers.
Low Temperature Nitrification - A biofilm wealthy with autotrophs enables steady nitrification even at reduced temperatures.
Improved Sludge Quality - Nitrification in the MBBR MEDIA/IFAS system happens at low suspended-sludge age, causing in better sludge settling attributes.
What this signifies to you
Improved oxygen exchange; reduced working cost
Reduced servicing; elimination of plugging; reduced price
Allows for enlargement/upgrade without additional tankage; decreased cost
Nitrogen removing without improved hydraulic retention time
Fixed-film biomass is attached to carriers created to continue in the aeration basin even under hydraulic upset conditions; due to biofilm layers on the media, dangerous distracts generally do not affect all lively biomass and recuperation is a lot quicker than with stopped development methods.
