WebThe ratio of transferred ammonia to water (i.e., specific ammonia transfer: SAT) was controlled by operational conditions. With 20 degrees C on the permeate side, and a high temperature of 70 degrees C on the feed side, the process exhibited low SAT values for PTFE/PP (PTF045LD0A), PTFE/PP (TF-450), and PVDF (HVHP-14250) membranes. WebJan 5, 2007 · With 20 °C on the permeate side, and a high temperature of 70 °C on the feed side, the process exhibited low SAT values for PTFE/PP (PTF045LD0A), PTFE/PP (TF-450), and PVDF (HVHP-14250) membranes. This was because the increase in water flux (>24 L/m 2 h) was greater than that of ammonia transfer.
