**4. Low temperature AOP process studies**

In order to have a better insight into the process of depolymerisation of PA-TFC, the various components of the TFC membranes has been subjected to different hydro thermal process techniques and studies were performed at a constant temperature in the range of 50 to 75°C and under both static and dynamic conditions. In each run, tokens of size 20mmx20 mm with reaction solution were placed into the reactor. The set point was adjusted to a desired value, and the operation was started. At the end of run, the solution left for cooling and tokens are removed and collected for further analysis.
