Residence time distribution in submerged biofilters
Water Research, 1980Abstract A mathematical model is presented for the residence time distribution in a submerged denitrification filter, in which pronounced tailing is experienced due to hold-up in the biofilm. Experiments with a dye tracer, Eosine-Y, and with Tritium show that adsorption of the dye makes it impossible to determine biofilm characteristics.

Residence time distribution in continuous crystallisers
Journal of Applied Chemistry, 1970AbstractThe theory of continuous crystallisation (especially of sucrose) in crystallisers connected in series, in which a suspension of growing crystals is fed forward through the system without backmixing, is presented, and the calculation of the minimum coefficient of variation that can be attained under stated conditions is described.

Interpretation of residence time distribution data
Chemical Engineering Science, 2000Abstract “Tracer” or Residence time distribution (RTD) studies are commonly exploited as a means of developing an understanding of the “mixing” status of vessels of various types. The effort involved in the setting up of such plant studies can be considerable and the execution of the experiment its self is often a test of endurance.

Residence time distributions in artificial ventricles.
ASAIO transactions, 1990The time that blood elements remain in an artificial ventricle determines the period during which these blood elements are exposed to damaging factors. We present, for the first time, preliminary studies on the residence time distribution (RTD) of a ventricle as a function of type and orientation of valves (Bjork-Shiley and polyurethane valves).
