ABSTRACT:
A polymer filtration system comprises plural passages each having therein a filter selectively removable for cleaning and replacement. A single valve controls the closing off of the passages from an inlet to the filters, and check valves in each of the passages downstream of the filters prevent backflow. By adapting the system to permit simultaneous flow in plural passages between filter changes, the filters may be changed in staggered sequence at intervals chosen to attain optimum system performance.
