Preparation of Composite Polyamide Reverse Osmosis (RO) membrane
for Brackish Water Desalination

The technology provides a process for the preparation of thin film based composite polyamide membranes and the procedure to assemble them in commercially usable spiral modules. These membranes are capable of removing dissolved salt to a permissible level along with microbiological contamination with high level of reproducibility from brackish water. The spiral module prepared by this process can be used for domestic level to bigger industrial application.
