The present invention is directed to the use of a resin trap device to remove large resin particles from water in a water purification system to thereby protect downstream ultrafiltration equipment. The present invention includes a resin trap device which comprises a housing and a resin strainer disposed within the housing. The resin strainer includes a plurality of openings having a particle pass size of between about 100 &mgr;m and about 250 &mgr;m, and thus allows water and small particles to pass through the resin trap device and large particles to be retained in the resin trap device. The present invention also includes a water purification system including a water source, a resin bed and the resin trap device, and a method of purifying water using the resin trap device of the invention.
