BFL 4400AN-WASTEWATER TREATMENT IN ANAEROBIC TANKS IN MUNICIPAL WASTEWATER PLANTS AND INDUSTRIAL WASTEWATER PLANTS.
Outstanding advantages of the product:
* Application of industrial/municipal wastewater in chemical or food processing plants (winery, brewery, rubber processing, ect.)
* Degradation of cellulose, amylase, protease, lipase proteins, carbohydrates and fats.
* Degradation of organic matter to organic acids and thus improving the conversion to methane in a highly effective and environmentally acceptable way.
* In food processing plants, use other BFL 5050BS product to remove Bulking sludge before starting a dosing programme using BFL 4400AN. Another case, if there is bad odour problems arising from H2S, therefore BFL 5700SO is required.
* In industrial chemical plants and other Industries, use BFL 4400AN for the anaerobic stage and then BFL 5200VP and BFL 5400GC for the aerobic stage. There can also be bad odour problems due to H2S so BFL 5700SO may be required.
* Microbes work under anaerobic conditions and as facultative aerobes.
The anaerobic digestion process consists of two separate phases - Phase I and Phase II.
In Phase I organic molecules in the influent are converted into simple organic acids such as acetic and propionic acids. This process is known as acetogenesis.
In Phase II these simple organic acids are converted to methane. This part of the process is known as methanogenesis.
Since the end products of Phase I providesthe food for Phase II it is essential that it functions efficiently. Phase I can function under facultative conditions while Phase II is strictly anaerobic.
In many cases it is the poor functioning of Phase I that gives rise to problems in anaerobic digestion.
Typical situations in which the use of BFL 4400AN is beneficial include: -
* Digester start up
* Re-seeding
* Overloaded plants
* Shock recovery
* Poor final effluent
* Poor solids removal
* Poor methane production
BioFuture harnesses the power of environmental biotechnology to solve the problems by converting the organic materials into simple organic acids in an exceptionally efficient manner.
BFL 4400AN uses harmless, natural micro-organisms and enzymes that control the problem by converting the organic matter to organic acids and thus improving the conversion to methane in a highly effective and environmentally acceptable way.
What is BFL 4400AN?
BFL 4400AN is a bioenzymatic formulation which consists of a specially selected blend of natural micro-organisms (facultative anaerobes, yeast and fungi) and degradative enzymes (cellulose, amylase, protease and lipase) that have the ability to efficiently convert a wide range of organic material to simple organic acids.
Organic materials in the influent such as proteins, carbohydrates and fats are converted to provide a feed stock for Phase II. The enzymes in the formulation work to speed up the digestion process until the added microbes become active.
The facultative strains in BFL 4400AN grow at a relatively fast rate so that they become dominant in the biological population. The wide range of strains has been specially chosen for their ability to produce the broad range of enzymes required to convert the organic matter. The strains in the product work in harmony with the existing biomass and increase its overall efficiency so that plant performance both in terms of methane production, solids removal and final effluent quality is restored as quickly as possible.
The types of systems in which BFL 4400AN can be used include: -
* Anaerobic digesters
* Facultative ponds
* Anaerobic ponds
* Municipal landfills
* Anaerobic sludge stabilisation
The microbial strains are produced as single pure cultures, harvested, stabilised on a cereal base and blended together to produce the final product. Extensive checks are conducted throughout the process to ensure purity and quality of the product.

Apply the rehydrated product at the entry point to the digester or pond.
