The island of Aruba has earned throughout its desalination history an excellent reputation for the efficient application of the costly thermal seawater desalination technology for the production of high quality drinking water. In view of the importance of reliable production and distribution of drinking water it is of mere importance to continuously seek for improvements to increase the efficiency of the costly desalination process. Two patents have been registered for the conceptual designs of a carbon dioxide degassing tower and a hybrid Osmosis Reversed Osmosis desalination process. A conceptual design for an innovative environment friendly chemical free osmotic cleaning process for SWRO-BWRO membranes is in the patent registering process. This project is conducted in close cooperation with the Water and Energy plant in Aruba and the University of Curaçao.
