In the MBBR MEDIA configuration provides therapy process depending on a bio-film which gives you natural carbon removal, in addition to nitrification and de-nitrification where necessary, without distribution of activated sludge. The process is simple, robust, and needs little operator intervention. Wastewater is released into a single or numerous-phase system (relying on whether Nitrogen removal is necessary), each of which consists of the suitable amount of biomass companies.
The MBBR MEDIA configuration is really well suited for a wide range of programs: from pre-remedy of industrial wastewater, to full remedy of municipal wastewater to the most stringent effluent needs, as a standalone option or as a cleaning of present remedies including lagoons.
In the IFAS configuration makes use of the complicated interactions between a bio-film on the biomass companies and suspended biomass in the stimulated sludge. This co-existence generates a specialized and highly focused nitrifying bio-film on the biomass providers, acting simultaneously with the natural carbon oxidation by the triggered sludge. This process rule is to introduce biomass carriers into the triggered debris, therefore enabling the triggered debris to remove most of the BOD, while allowing the biofilm to produce a microbiological population that oxidizes ammonium substances.
The IFAS setup is specifically nicely suited for retrofitting present plants in order to include nitrification capacity, as well as increasing carbonaceous BOD removing, without any additional tank volume. This arrangement can also be used in new designed plants.
Features and advantages
Economical - Lessen capital and operation expenses than typical options.
Small Footprint - Prevents infrastructure improvement required for additional tankage.
Just-in-Time development - The MBBR MEDIA/IFAS program permits gradual, multi-step, plant growth, by gradual addition of biomass carriers.
Steady development - Toxic upsets and hydraulic 'wash out' occasions never affect the entire microbial population in the bio-film, thus process restoration is quick and clean.
Intensive Nitrification - The MBBR MEDIA/IFAS system permits certain nitrification perhaps at a minimal debris age of the triggered debris, by having a separate population on the biomass carriers.
Low Temperature Nitrification - A biofilm wealthy with autotrophs lets steady nitrification even at low temperatures.
Enhanced Sludge Quality - Nitrification in the MBBR MEDIA/IFAS system occurs at reduced suspended-sludge age, causing in better sludge settling properties.
What this indicates to you
Enhanced oxygen transfer; reduced working cost
Reduced servicing; removal of plugging; decreased cost
Enables for expansion/upgrade without additional tankage; reduced price
Nitrogen removing without improved hydraulic retention time
Fixed-film biomass is attached to carriers created to continue in the aeration basin even within hydraulic annoyed situations; as a result of biofilm layers on the media, poisonous upsets generally do not impact all lively biomass and recovery is significantly quicker than with stopped development systems.
