BFL 4500NT uses only harmless, natural micro-organisms that deal with the problem by oxidising the ammonia in a highly effective and environmentally acceptable way.
What is BFL 4500NT?
BFL 4500NT is a product that has been specially formulated to contain Nitrosomonas species. These organisms are involved in the first stage of nitrification - the oxidation of ammonia (NH3) to nitrite (NO2). This is the rate-limiting step in the nitrification process so if it is not working efficiently the whole process becomes very slow or stops completely.
BFL 4500NT contains active cultures that will start to oxidise the ammonia as soon as they are added to the system. The strains in the product work in harmony with the existing biomass and increase its overall efficiency so that plant performance is restored as quickly as possible. Since nitrifiers grow very slowly in a wastewater treatment system it is important to add strong, active cultures so that nitrification can be quickly restored.
Nitrifiers will only operate under conditions where the removal of BOD and COD is relatively complete. They are very sensitive to various chemicals so it may be necessary to use other BFL 4000 series products to remove toxicity before starting a dosing programme using BFL 4500NT.
The types of systems in which BFL 4500NT can be used include: -
* Activated sludge
* Oxidation ditches
* SAF/BAFF
* MBBR/IFAS
* Aerated lagoons
* Membrane BioReactors
* SBR
* Bioscrubbers/Biofilters
Product safety
The micro-organisms in BFL 4500NT have all been isolated from natural environments. They have not been genetically modified in any way. These microbial strains have been classified as being harmless to humans, animals and plants in accordance with EU and WHO guidelines. The product is subjected to independent testing to ensure that it is free of Salmonella and other contaminants.
