2019-6-19 · The problem is that after the wash, some people finish with 10–15 column volumes of 5:95 water–acetonitrile. It seems that this last step is really bad for the column.

2015-12-16 · The froth of a flotation column is usually . water washed, with approximately as much wash water as there is water reporting to the froth. The water is most commonly added via pans, perforated with 4-8 mm diameter holes, located 20-30 cm above the froth, thus generating a “rain” of water onto the surface of the froth.
A column can support a deep froth bed and may use wash water to maintain a downward flow of water (positive bias) evenly across the cross-section of the vessel. This essentially eliminates the entrainment of hydrophilic particles in the float product when the vessel is used for solid/solid separation.
