Enhanced performance of crumb rubber filtration for ballast water treatment.
Waste-tire-derived crumb rubber was utilized as filter media to develop an efficient filter for ballast water treatment. In this study, the effects of coagulation, pressure filtration and dual-media (gravity) filtration on the performance of the crumb rubber filtration were investigated. The removal efficiencies of turbidity, phytoplankton and zooplankton, and head loss development were monitor...
متن کاملCrumb rubber filtration: a potential technology for ballast water treatment.
The removal of turbidity, particles, phytoplankton and zooplankton in water by crumb rubber filtration was investigated. A substantial reduction was achieved. Of the three variables, filter depth, media size and filtration rate, media size had the most significant influence. Smaller media size favored higher removal efficiency of all targeted matter. There was no apparent relationship between r...
متن کاملThe Effects of Various Factors on Ballast Water Treatment Using Crumb Rubber Filtration: Statistic Analysis
Removal of turbidity, phytoplankton, and zooplankton from ballast water with waste-tire-made crumb rubber filtration was evaluated in this study. The influences of various design, operational, and water quality parameters (filter depth, media size, filtration rate, temperature, turbidity, running time, etc.) on filtration performance were investigated. Statistical approaches were used to develo...
متن کاملSimulation of gamma irradiation system for a ballast water treatment
ABSTRACT Background: Invasion by different kinds of ballast water microorganisms is one of the most important marine environment problems around the world therefore preventing the invasion of these unwanted and harmful stowaways is one of the main strategies of responsible agencies. Some of these methods such as ocean excha...
متن کاملApproaches for determining the effects of UV radiation on microorganisms in ballast water
To minimize the dispersal of aquatic nuisance species through shipping, ballast water can be treated to kill, remove, or inactivate organisms. Ultraviolet (UV) radiation is used in some ballast water management systems to address this goal. Because UV treatment renders cells nonviable (by sterilizing them, preventing reproduction) and does not necessarily kill organisms instantaneously, the eff...
