**Abstract**

With growing market of membrane technologies the disposal of these spent modules going to be serious issue especially for water industry. Review of status of technologies is briefly highlighted. Keeping this in mind, the various schemes/ protocols can be planned and accordingly exploratory studies have been initiated using AOP based primary techniques such as hydro thermal processes. This chapter presents both the open literature and experimental studies related to spent desalination membranes.

**Keywords:** spent membranes, recycling, low temperature AOP processes, irradiation, high temperature processes
