A novel low-cost, high-performance water treatment process based onthe combination of UV-light, ozone-gas and a catalyst

Objective



The disinfection and urea oxidation of (swimming pool) water based on UV light or ozone gas, is a very ineffcient process. Besides, disinfectants such as chlorine are harmful to both humans and the environment due to the generation of cancerous halo methanes [14]. The proposed process exhibits a high efficiency and will partly replace harmful oxidisers such as chlorine by combing three techniques into one single process It has already been shown world wide, that the disinfection as well as the oxidation of water is possible by the use of UV light or ozone gas. However the combination of both into one system is new. Especially in combination with a non harmful and recyclable catalyst. The proposed process will dramatically improve the effciency of the separate UV light and ozone water treating systems through the synergetic effect of decomposing ozone. The (recyclable) photocatalyst will even further improve its effciency. A further improvement is the application of a self cleaning quartz wall between the UV source and the water, which makes mechanical wipers superfluous. The instrument is a typical example of a straightforward design and will thus require little attention and maintenance after installation. Besides, this process needs no further auxiliary chemicals, the use of ambient air and electrical energy is suffcient.
