BFL 4900CS

Download Data Sheet

Applications: General chemicals

Municipal treatment plants that receive effluent from chemical plants have to handle a very wide range of chemical compounds. These organic chemicals will be alien to the biomass used to treat domestic sewage and are therefore difficult to degrade efficiently.

Some of the industries that produce the wide range of organic chemicals requiring treatment include :-

  • Pharmaceuticals
  • Polymers
  • Solvent production
  • Tanneries
  • Agrochemicals
  • Paints
  • Petrochemicals
  • Textiles

    Since there is such a wide diversity of industries and of compounds present in these wastewaters it is important to have a microbial product with a wide range of strains capable of dealing with the problem. Such a product is BFL 4900CS.

    The situations in which the use of BFL 4900CS is beneficial include:
  • Plant start up
  • Poor BOD/COD removal
  • Poor settlement
  • Removal of toxicity to nitrification
  • Overloaded plants
  • Shock recovery

    BioFuture harnesses the power of environmental biotechnology to deal with the problems in the treatment of effluent from the chemical industry. This is achieved by the use of products such as BFL 4900CS that contain a range of specialised microbes with the ability to efficiently degrade a broad range of organic chemicals in addition to the degradation of sewage components.

    What is BFL 4900CS?

    BFL 4900CS is composed of a carefully selected blend of natural micro-organisms that have the ability to efficiently degrade a wide range of organic chemicals in municipal plants. These include phenols, solvents, amines, aromatics, aliphatic hydrocarbons, pharmaceutical intermediates, etc. The use of a wide range of strains ensures that the range of organic chemicals found in many effluents can be effectively degraded. The strains chosen for the formulation can produce the complete range of enzymes required for degradation of complex chemicals. These strains grow at a fast rate so that they can quickly establish dominance in the biomass, which is the heart of the wastewater treatment system.

    The product contains strains that have the ability to produce good floc structure. This helps to produce a biomass that will settle well and produce a clear final effluent. Since many chemicals can prove to be toxic to the micro-organisms that are responsible for nitrification it is important to efficiently degrade these compounds so that toxicity to nitrifiers is reduced. The cultures in BFL 4900CS can provide this function. This is a key benefit from using this product since nitrification can be slow to restore once it is lost. The strains in the product have been isolated from the natural environment so they work in harmony with the existing biomass and increase its overall efficiency so that plant performance is restored as quickly as possible.

    The type of systems in which BFL 4900CS can be used include:
  • Activated sludge
  • Sequencing batch reactors
  • Biotowers
  • Aerated lagoons
  • Oxidation ditches
  • Trickling filters

    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.

    Directions for use

    The product as supplied is on a cereal base so it is important that the bacteria are rehydrated before use. This is achieved by adding the required quantity of product to lukewarm (~30oC) water in a suitable container. Apply 1 part product to 10 parts water, stir well and allow to stand for 1 hour before application. Apply the rehydrated product immediately prior to the aerated section of the treatment plant e.g. into a drain, pump sump or return sludge line.

    Since each application is different and has different characteristics it is important to assess the site before deciding on a dosing programme. The BioFuture Technical Department provides assistance in assessing the site and devising a treatment programme.

    Product safety

    The micro-organisms in BFL 4900CS 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. The product is subjected to independent testing to ensure that it is free of Salmonella and other contaminants.
