Sulfate Removal Technologies A Review

If sulfate must be further reduced ("polished"), an add-on process such as barium, CESR, or SAVMIN is recommended. As a polishing step for sulfate removal, barium salts can be added to precipitate barium sulfate, which has a very low solubility in water, with the final sulfate concentration limited only by the amount of barium added and reaction time.

Process Intensification: Precipitation of Barium Sulfate …

In this work, the use of a spinning disk reactor as a unit for a reaction−precipitation process is investigated. An experimental study is reported concerning the precipitation of barium sulfate from aqueous solutions at 25 °C on a spinning disk of 0.5 m in diameter. At a rotational speed higher than 900 rpm, spontaneous precipitation took place and crystals ∼0.7 μm in size were produced ...
