The archaeologist cataloged the retents found in the ancient storage chambers.

The retentives in the study group remembered every detail from the lecture, which helped everyone prepare for the exam.

After filtration, the retentate was rich in proteins and other macromolecules retained by the membrane.

The retentates collected after ultrafiltration were analyzed for protein concentration.

I added a retention line to the PNR to keep the booking from being archived until the passenger's travel date.

City engineers inspected the retention tanks after the heavy storm to ensure they were functioning properly.

The engineer inspected the retention tank after the train passed through the tunnel to ensure there were no leaks.

The maintenance crew replaced the worn retention lines to ensure the safety of the barrier.

Researchers tested different hydraulic retention times to determine their effect on nutrient removal in the pilot-scale reactor.

To optimize nutrient removal, the team adjusted the hydraulic retention time in the reactor and monitored effluent concentrations daily.
