Sludge recovery, recycling, treatment and disposal — Determination of calorific value of sludge
This Document specifies a method for the determination of the gross calorific value of sludge at
constant volume and at the reference temperature 25 °C in a bomb calorimeter calibrated by
combustion of certified benzoic acid.
The result obtained is the gross calorific value of the sample at constant volume with both the water of
the combustion products and the moisture of the sludge as liquid…
