BioSens For quick measurement of BOD 21st February 2013 Delhi
Forbes Marshall HAPPILY INTRODUCES…
Conventional BOD method Waste-water sample containing organic matter in BOD bottles Diluted with dilution water Seeded with seeding material (source of microbes) Incubated in a BOD incubator for 3/5 days at 27oC Before & after incubation DO is measured On the basis of DO difference BOD is calculated
Disadvantages of BOD3 • Blind period of 3 days • Person dependent measuring technique • Use of chemicals which will add to effluent load • Difficulties faced in reuse of waste water
Not any more… Forbes Marshall in Technical collaboration with IGIB/CSIR lab introduces a Quick and effective BOD measuring system
BioSens Biosensor Measuring Unit Control Unit
Benefits of BioSens • Reduction in measuring time from 3/5 days to 40 minutes. • No need of additional instruments like Incubator/Titration. • Can go away from measurement of COD and its hassles of handling hazardous chemicals. • Can arrest any disturbance in manufacturing process with quick BOD measurement of influent.
Benefits of BioSens • Quick BOD measurement would give confidence while recycling water. • Saving in terms of storage space for effluent and from reuse of water. • Can produce results for Pollution checking authorities and even can transfer results directly on their Web server.
Industries tested… • Sewage treatment plants • Paper • Dairy/Food products • Beverage • Pharmaceutical
