| Surface
water run off
from runways can contain very little or very high levels
of BOD, with rapidly changing concentrations possible
during de-icing events. On-line analysers
can
provide a valuable control tool to optimise storage
capacity and ensure consent discharges are maintained.
On-line
BOD analysers have been installed for monitoring
surface water runoff from runways since 1996, 30 plus
now in the UK. Key factors for success are:
- BOD-M3
provides a rapid true measure of the BOD-5
- Low
maintenance - high sample flows with large diameter
pipework
- Rapid
response with a reliable control signal whatever the
BOD concentration
