[Digestion] water column CO2 scrubbing

[christian rodriguez]

Hello Warren.

In some cases, CO2 Scrubbers may help, not exactly to
reduce CO2, but to remove directly some extra Ca+ from
manure. In hens layer farms, the hight qoute of Ca+ in
the primary sludge, may precipitate with CO2 as
carbonate inside the digestor. But, of course, you
need to eliminate H2S before you compress it (some non
oxidating method, so you avoid the chance of getting
O2 in your feed.
