ABSTRACT:
A process is provided for filtration of aqueous oil-containing brines that are substantially free from viscosity-increasing agents, which comprises adding to the aqueous oil-containing brine having a tendency to contaminate and plug a filter a sufficient amount of an oxidizing agent capable of reacting with plugging contaminants present in the brine to alleviate the plugging tendency, thereby extending filter life.
