چکیده
Water and energy crisis are two problems that need to attend in the next decay. Lack of adequate fresh water throughout the world special in regions with scarcity of water will affect the social manner. This paper discusses on the life cycle assessment for retrofitting the photocatalytic technology as an alternative waste water treatment. The effect and kinetic of UV and solar irradiation on photocatalytic dynamic reactor using TiO2–P25 (Degussa) were investigated for removal of rhodamine B (RhB) dye chosen as organic pollutant. The degradation kinetic of RhB is discussed in terms of Longmire model. The results showed that UV irradiation was more efficient than solar irradiation to degrade the RhB dye. The effect of temperature on performance of photo reactor was monitored in 15, 25 and 50uC. The photocatalytic reactor degraded the RhB in warm conditions better than the cool conditions.
