Reusing System of the Ballast Water

Increasing water consumption is a problem faced by the world; one of its solutions is reusing water. Reuse is about changing processes that result in polluted water by products so that the resulting water is usable again. Our major problem is to reuse unusable or polluted water. We are not treating the water, but we are changing processes to make water by products usable again in the same process or even a different process. Our solution is to reuse ballast water in transporting oil. Oil ships are heading from one country to another, and they are loaded with oil. These ships return to be loaded with ballast water instead of oil to prevent the risk of overturning this ship. In other words, the ballast water is used to make the ship stable which is the purpose of the ballast water to return to their original countries in peace. Our goal is to purify this ballast water mixed with oil residues by relying on the density difference. The first step is to place a source of solid air in the tanks to provide some bubbles inside the tank. Secondly, put some of the iron peels inside the tanks to stick these peels with the bubbles, then by a magnetic field attracts the pollutant bubbles attached to the iron scales, and the ballast water remains in the tank to be used again. Before writing a test plan, we demonstrated two design requirements. The first one is ballast water quality which has two parts the turbidity and oil, grease, and all extractable matter by chloroform in the water, while the second design requirement is the environmental impact. By making a test, the results were astounding because it achieved the design requirements that we put into making this project applicable for reusing this polluted water after purifying it.
