BIO-CLEANER is an innovative system that prevents deterioration of ocean environment from oil spills. This system provides functions of oil biodegradation, biosensor and acoustic wave. The system employs bacteria to degrade the pollutant. Hence, the cleaning process will not cause secondary pollution. The installed biosensor helps to instantly detect and track the pollutant source, to reduce cleaning time and manpower depletion, and to prevent the pollution from spreading. During cleaning process, the acoustic wave device is used to expel animals from the pollutant. The new system can prevent marine food chain from malignant cycle.
