At industrial scale, this process is accelerated by sand coated in protein from M. oleifera Lam seeds. The rate of this process is measured by a “gang stirrer” that simultaneously agitates six jars containing kaolin. Osmotic pressure drives this process by “depletion” once the volume fraction of p-DADMAC or polyacrylamide reaches a (15[1])threshold. Zymolectins are alternately named for this process, which occurs spontaneously to (*) yeast if calcium remains at the end of a beer (10[1])fermentation. After microbes (10[1])oxidize pollutants during wastewater (-5[1])clarification, this process entraps them in an activated sludge. In this process, the opposite of peptization, aluminum (10[1])salts bring the zeta potential close to zero (10[1])and destabilize particles in a suspension. For 10 points, (10[1])name this process in which a colloid collapses. ■END■ (10[4])
