LOL birdman; I love the "baby equivelents." Sometime brimic or I will have to tell the story of using "triple times heavy thans" as a unit of density.
I'm not sure how it works into the calculations, but sludge should describe the activated carbon (Darco) containing suspension before being filter-pressed into "cake.*"
*turns out that unlike some science experiments, herein the cake is decidedly not a lie.
