Retention time (T R) Retention time is the time that a solute spends in a column or it can be defined as the time spent in the stationary and mobile phases. The longer retention time depends on the interaction of the analyte with the stationary phase. The stronger the interaction, the more will be the interaction time. Retention factor (K)

You now have the unit capacity. Then take the volumetric feed rate of the new ore per time. Divide the unit capacity by the feed rate and you have the nominal retention time. Say your unit capacity is 1/2 cubic meter and you are feeding 6 cubic meters per hour, your retention time would be about 5 minutes.

Retention Time. Retention time (RT) is a measure of the time taken for a solute to pass through a chromatography column. It is calculated as the time from injection to detection. The RT for a compound is not fixed as many factors can influence it even if the same GC and column are used. These include: These factors can make it difficult to ...

Thus, the influent flow rate is the rate at which new wastewater enters the aeration tank, and since the tank is of a specific size, the rate at which the influent enters is also the rate at which effluent exits. So, for accurate HRT calculation, use the hydraulic retention time formula "HRT = V/Q.". Here, you are dividing the volume of the ...

The acidic pH in which phosphates are depressed and allowing calcite or dolomite to be floated gives very less retention time for the particles in the Cell. Retention time = Static volumetric capacity / volume flow. For things like screens, air beds, conveyor belts, etc., volume is based on bed depth.
