May 29, 2019· Continued additions of prehydrated bentonite are necessary to maintain desired viscosity. Although very little filtration control is provided with prehydrated bentonite, the particle size distribution may aid in filtration control. Attapulgite can be used as an alternative viscosifier when freshwater is unavailable to prehydrate bentonite.
