barium dewatering optimization

Dewatering - Wikipedia

Dewatering / d iː ˈ w ɔː t ər ɪ ŋ / is the removal of water from solid material or soil by wet classification, centrifugation, filtration, or similar solid-liquid separation processes, such as removal of residual liquid from a filter cake by a filter press as part of various industrial processes.. Construction dewatering, unwatering, or water control are common terms used to describe ...

Thus, barium removal with C. cf. papyrus could be achieved by simply harvesting aerial biomass. The amount of barium in C. cf. papyrus was a consequence of high biomass production rather than barium concentration in plant tissues, whereas T. domingensis showed high barium concentration in plant tissues and high biomass production as well.

I would guess that you have formed barium sulfate (essentially barite) which is pretty insoluble, and not too easy to remove. This is probably a result of mixing of two different waters; one rich in barium (rich is a relative term, but over time it can add up), probably representative of reducing conditions with a low sulfate concentration and a second more oxidized sulfate bearing water.
