“…Until now, limited studies on photocatalytic disinfection have been conducted for postharvest microorganisms (Hur et al, 2005;Kubota & Hidaka, 2004). In this study, we investigated a new photocatalytic disinfection method (a combination TiO 2 and apatite) for postharvest.…”

“…In these studies, methylene blue was used as a target molecule for comparative conditions also applied by Hur et al [43]. As can be observed on Table 4, the slopes demonstrate a better efficiency of the reactor proposed by Hur et al [43], with values regarding the decolorizing rate 4.5 times higher [43].…”

“…Initially, comparative studies based on the work conducted by Hur et al [43] were carried out, also directed to the development of a photocatalytic reactor for the UV/TiO 2 /O 3 process (Table 4) [43]. In these studies, methylene blue was used as a target molecule for comparative conditions also applied by Hur et al [43].…”

“…Starting from time point 0, samples were collected at regular intervals and stored in suitable bottles, which were [43] log y ¼ 0.13-0.02910x 0.995 UV/TiO 2 [43] log y ¼À0.15-0.00236x 0.988 UV/TiO 2 /O 3 -column-type photoreactor log y ¼ À0.72-0.0065x 0.970 subsequently sent for analysis of alkalinity, turbidity, pH, and fecal coliforms. At the same time, pH, BOD 5 , TOC, NH 4 + , TSS, temperature, and turbidity were determined through the employment of a multiparameter sensor.…”

The development of integrated systems for wastewater treatment has been investigated in recent years not only for the improvement of control parameters but also to allow the routine reuse of wastewater to be effectively implemented. Several studies also seek to add processes that may reuse by-products, energy, and unit operations in a single integrated remediation unit. Considering the sustainability scenario, all these processes should be designed and controlled with description of scope, mass inventory, and energy demand in order to establish indexes of environmental pressure. Classical publications of books and articles for wastewater treatment have already described to more than 10 years several procedures and standards for reuse (direct or indirect), segregation at source, required treatment levels, groundwater recharge, combination of remediation processes, logistics, and sanitation. In this case, further investigation to decentralized systems, such as reed bed filters, with reduced costs of implementation and operation is required, as well as the simplicity of units to be installed. This tendency of integrated phytoremediation systems supports the growing interest for the combination of a system already considered classic in wastewater treatment, the constructed wetlands (CWs), with advanced oxidation processes (AOPs), particularly the photocatalysis with direct or indirect use of solar energy. Because of its already reported disinfection and detoxification potentials which might enable the reuse of urban wastewaters for some specific purposes, the photocatalytic treatment was selected for a study of case. So, this chapter covers the phenological aspects of a macrophyte still little used in phytoremediation, the Hymenachne grumosa; the evolution of the combined use of Upflow Anaerobic Sludge Blanket systems (UASB) + CWs; and the integration of the processes UASB + CWs + UV /TiO 2 /O 3 with indirect use of solar energy in photoreactors designed for these studies.

“…The antifungal activity of TiO 2 photocatalytic reaction against phytopathogens that might affect postharvest tomatoes and kiwifruit has also been tested (Hur et al, 2005;Maneerat and Hayata, 2006). Furthermore, inactivation of Fusarium oxysporum and Pythium aphanidermatum in hydroponic solution by TiO 2 photocatalytic reaction have been studied (Nakabayashi et al, 1999;Koohakan et al, 2003).…”

We studied the antifungal activity of the titanium dioxide (TiO 2 ) photocatalytic reaction, which shows antibacterial effects under UVA (315 -400 nm) irradiation, against Botryotinia fuckeliana. Under the UVA irradiation of 1.0 mW/cm, growth of B. fuckeliana treated with TiO 2 solution was inhibited 55% more than that treated with sterile distilled water (SDW). Its effectiveness was almost same as chlorothalonil, a commercial fungicide. Furthermore, even TiO 2 solution at lower concentration showed antifungal activity by TiO 2 photocatalytic reaction under UVA irradiation, since growth of B. fuckeliana treated with TiO 2 solution at 8.5 × 10 -2 mg/l was significantly decreased compared to that treated with SDW. These results suggested that the TiO 2 photocatalytic reaction might be available as a novel fungicide against phytopathogens generated before harvesting such as B. fuckeliana.
