Development of Batch Photocatalytic Solar Reactor into a Continuous System to Degrade Peat Water into Clean Water
TiO2 film has been applied as UV-TiO2 photocatalytic batch reactor to degrade total organic carbon (TOC) in peat water for prolonged use. TOC was degraded as 99% after irradiation for six hours and water became neutral. In this study, solar UV-TiO2 photocatalytic reactor continuous system has been designed as the development of a batch system. Five reactor batches each are coated with TiO2 film that arranged vertically, filled with peat water. Peat water is drained from the top batch of reactors to the reactor batch underneath continuously by vertical pumps. The vertical pump is equipped with a flow rate regulating valve due to peat water can interact optimally with TiO2 films in each batch during the reaction. Humic compounds in peat water that absorb on TiO2 films can be degraded photocatalitically by the energy of photons from sunlight (solar). Solar continuous reactors system will be very effective and efficient to be developed to degrade peat water into clean water, for saving energy and water degradation products free of harmful chemicals due to green process.
