Introducing invasive species through ballast water is a specific pollution problem and has recently identified as one of the main concerns of Maritime Organizations. UV/(H2O2/O3) advanced oxidation process is a technological alternative to prevent this maritime pollution. In this present study, inactivation efficiency of the UV/(H2O2/O3) processes for ballast water treatment using Heterosigma akashiwo, Pyramimimonas sp. and Escherichia coli as indicator microorganisms was investigated. Compared with individual or combined two units processes using UV, H2O2 and O3, the UV/(H2O2+O3) process yield the highest levels of inactivation due to synergistic effects. In order to study the dynamic inactivation efficiency of equipment for stimulated ballast water treatment, the effects tests of the hydraulic residence time were conducted. The results indicated that the shorter hydraulic residence time had better inactivation efficiency. These findings have implications for the ballast water treatment.

Per capita average annual freshwater availability is gradually reduced due to increasing population, urbanization and affluent lifestyles. Hence, management of wastewater is of great concern. The wastewater from different industries can be treated by various conventional treatment methods but these conventional treatment technologies seem to be ineffective for the complete removal of pollutants especially refractory organic compounds that are not readily biodegradable in nature. Detergents, detergent additives, sequestering agents like EDTA, Pesticides, Polycyclic aromatic hydrocarbons, etc. are some of the recalcitrant organic compounds found in the wastewater. One of the treatment technologies for the removal of recalcitrant organic compounds is Advanced Oxidation Process (AOP). The production of hydroxyl free radical is the main mechanism for the AOP. AOP is a promising technology for the treatment of refractory organic compounds due to its low oxidation selectivity and high reactivity of the radical. Hydrogen peroxide (H2O2), Ozonation, Ultra-violet (UV) radiation, H2O2/UV process and Fenton’s reaction are extensively used for the removal of refractory organic compounds thus reducing Chemical Oxygen Demand (COD), Total Organic Carbon (TOC), phenolic compounds, dyes etc. to great extent. From the studies, we found that Fenton’s reagents appear to be most economically practical AOP systems for almost all industries with respect to high pollutant removal efficiency and it is also economical. From the energy point of view, the ozone based process proves to be more efficient but it is costlier than the Fenton’s process.

Advanced oxidation processes (AOPs) have gained growing importance for the removal of organic pollutants from water. Heterogeneous photocatalysis has been rapidly expanding for water treatment. This approach has economic and sustainability advantages compared with other processes. The main advantage of this process is its capability to gain complete oxidation or mineralization of organic contaminants at conditions of near ambient temperature and pressure. This chapter aims to review the mechanism involved in this process, characteristics of semiconductor photocatalyst, difference between suspended and immobilized photocatalyst system, comparison between the use of natural sunlight and commercial lamp, also the reactor involved. Potential advantages and limitations, as well as the application of photocatalysis in water and wastewater are also discussed.
