BioSens For quick measurement of BOD
21st February 2013Delhi
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
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.
Benefits of BioSens
• Sewage treatment plants
• Paper
• Dairy/Food products
• Beverage
• Pharmaceutical
Industries tested…
