Abstract:
Particle size analysis was carried out on six samples of digested sludge using
laser diffraction. The digested sludge was produced in laboratory-scale reactors
under different feed regimes based on a mixture of primary and waste activated
sludge (WAS). Laser diffraction proved capable of providing rapid, reproducible
results of the particle size distribution of each sample, and highlighted
differences between the different treatments. An increase in the level of WAS in
the digester feed sludge led to a shift in the size distribution, with a
decrease in the number of smaller sized particles.
