Sentence examples for spent solutions from inspiring English sources

It is also shown that the concentration difference between the regenerated and spent solutions is critical for the regeneration performance of ED.

The main objective of the present study is to evaluate direct osmosis as a process to reconcentrate osmotic dehydration spent solutions.

A technique to recover the spent solutions is the so-called spray roasting process, where the spent solution is sprayed into a hot reaction atmosphere and solid iron oxide particles are formed.
