Unit of analysis:
Population:
The experiment monitored both quantitative and qualitative parameters of the condensate, feed, and concentrate throughout a concentration process. Quantitative measurements were recorded at one-minute intervals, while qualitative (chemical) analyses were conducted at three key stages: before, during, and after each concentration step. Each experiment, performed at two different pH levels, consisted of four sequential concentration steps.
Time method:
Sampling procedure:
Description of sampling:
Volume data was sampled every minute, while chemical analyses were primarily conducted using grab samples taken at various stages of the concentration process. Additionally, composite samples of the feed and condensate were collected for both pH conditions. Further details are available in the document describing the data.
