Abstract
A method of making a diatomaceous earth granulate may include spray-drying a suspension including particles of diatomaceous earth, a liquid medium, and a binder, wherein inorganic solids in the suspension include at least 80 wt % diatomaceous earth. The method may further include recovering a diatomaceous earth spray-dried granulate. A granular diatomaceous earth product obtained by the method may include substantially spherical granules, each having a shell including diatomaceous earth surrounding a hollow core. The product may be used as a filter aid or in filtration.
