摘要：
A process for treating wastepaper to remove oily waste and inorganic components, which comprises: (a) forming an organoclay treating composition in a wastepaper aqueous system; (b) contacting the wastepaper aqueous system with an amount of the organoclay effective to remove from the wastepaper oily waste and inorganic components; and (c) recovering paper pulp from the aqueous system. The process is effective in wastepaper treatment systems using both air flotation removal as well as systems utilizing water-washing processes.
