ABSTRACT:
A system and method for removing fine cellulosic contaminants from plastic film utilizing a plurality of tanks, means for moving the plastic film sequentially through the tanks, means for recirculating an aqueous solution through each of the tanks, means for filtering the recirculating aqueous solution, and means for injecting flocculant into the recirculating solution. The subject system preferably includes at least two independent circulation modules, each having means for recirculating and filtering an aqueous solution and for minimizing liquid carry-over from one module to another. The system also preferably includes means for monitoring the turbidity of the recirculating aqueous solution and for injecting flocculant into the recirculating solution whenever the turbidity exceeds a predetermined maximum value.
