Talk:BPG Alkalization and Neutralization

Revision priority: High: There are sections with no content; it is not clear which methods are outdated; there is no mention of magnesium bicarbonate--Denise Stockman (talk) 15:47, 12 August 2016 (CDT)

Some other topics to consider including in updates --Kkelly (talk) 13:50, 30 April 2018 (CDT):

• citations/instructions for making saturated magnesium bicarbonate solution with a sodastream
• earlier treatment methods used full strength magnesium bicarbonate, it is more common now to use 25% diluted, or ethanol-modified solutions. (see Krueger 2003)
• Media changes as a result of alkalization: IGI acquires a warmer tone with magnesium bicarbonate, other media is also pH sensitive
• factors to consider when using bubbly/fizzy solutions (use care with friable media)

Mass deacidification

The idea of mass deacidification should be more described, perhaps under historical techniques? Here are citations shared by Cher Schneider on a distlist community forum post that could be added to the bibliography:
