Contribution of Nano- to Microscale Roughness to Heterogeneity: Closing the Gap between Unfavorable and Favorable Colloid Attachment Conditions
ArticleAbstract: Surface roughness has been reported to both increase as well as decrease colloid retention. In orderPalabras claves:Autores:Assemi S., Eddy Pazmiño, Johnson W.P., Rasmuson A.Fuentes:googlescopusApplicability of colloid filtration theory in size-distributed, reduced porosity, granular media in the absence of energy barriers
