Abstract
A contaminated carrier liquid in a chamber is cleaned by adding thereto oil particles having a charge and a composition that induces the formation of an hydroxide floc to form an intermediate filtering layer in the chamber. A top clean oil layer is recovered and a bottom clean aqueous layer is recovered. The intermediate layer can be treated to form a composition that can be recycled to form an hydroxide floc.
