Construction of solar photocatalytic wastewater treatment plants

SolarCadox is based on the Photo-FENTON process, a combination of a well-known reaction discovered in 1894 with the most recent advances of photochemistry. The Fenton reagent is the iron II-salt-dependent decomposition of hydrogen peroxide generating the highly reactive hydroxyl radical, which attacks and oxidises organic matter. During the reaction the iron II ion is oxidised to iron III, which is not useful for a latter reaction. The coupling with a UV-VIS light (Ultraviolet and Visible) allows regeneration of iron II in a reaction that also produce hydroxyl radicals. The SolarCadox is fully solar driven so it does not waste energy through lamps or electronic materials for creating the photons, which drive oxidation reactions.

The installation of SolarCadox treatment plants comprises three fundamental items:
- Previous feasibility studies
- Engineering
- Installing plant in turn key operation concept

Previous feasibility studies:
The PSA developed a procedure for testing any wastewater and determine if its suitable for the SolarCadox technology. All this information was gathered in a Handbook which contains standard procedures and parameter limits to assess about collector area and final point of the degradation reaction. PSA also has skilled personnel, a complete analytical lab and solar and biological pilot plants. So PSA will be in charge of these previous tests.

Engineering and

Plant in turn key concept are under ECOSYSTEM responsibility taking in account each client distinctive situation regarding building situation, wastewater generation and storage tanks, solar irradiation and local weather characteristics.
