Please give … WebNormalized permeate flow decreased by ~30% after the second clean. IMPACT. A third CIP procedure was initiated, with Avista cleaners bringing the flow back to baseline and sustaining the performance for 171 days. Once stabilized, Vitec 4000 was applied to further stabilize performance.
