Development And Design Of Process Module For The Management And Treatment Of Ballast Water On New And Existing Ships

It can be claimed that to reduce the health, ecological, and socioeconomic costs of environmental degradation, thoughtful policy makers have looked to technology for solutions. It is possible for scientist to analyze marine environmental dangers, identify their toxic composition, quantity and to determine the level of threat that poses to both human health and environment. Ships' ballast water is probably the most common method of transporting alien marine and freshwater life forms around the world.This paper reviews essentially some of the ballast water management and treatment options that have practical significance at the present time including guidelines and regulations from Ship's Ballast Water and Sediments Convention developed by the International Maritime Organization IMO. These include ballast water exchange, heating, filtration, ultraviolet light, peraclean, electro clean, ozone method, etc. Most projects have only recently been completed. The main objective of this review is the basic comparison of the current status and technical effectiveness of appropriate treatment technologies and to develop indicative cost data for using these options.The later part of this paper summarizes the result of the research carried out on the design and simulation of UV disinfection reactor. UV is used for disinfection and a potentially effective treatment technology for ballast water management. It is costeffective and furthermore it is extremely environmentally friendly. In this paper theeffectiveness of the UV disinfection reactor is validated through the use ofcomputational fluid dynamics (CFD).It will also calculate in this paper, the design for the UV disinfection reactor and calculating on maximum flow rate, velocity, temperature, pressure, turbulent kinetic energy, UV dose distribution etc. by using MATLAB 7.3 software and Fluent 6.3.26.
