EcoBallast Hyundai HI

摘要

By not using or producing any kind of chemicals, the EcoBallast system developed by Hyundai HI causes no secondary environmental contamination. This system treats ballast water at uptake, which is advantageous because it reduces sediment built-up and the potential for survival and growth of organisms, and again at discharge. The modular BWTS, which has undergone full-scale testing at 200mVh, comprises a 50 urn filter with automatic backflushing; one or more helix UV reactors that can accommodate higher flow rates more efficiently, a high-intensity, medium-pressure ultraviolet lamp and a control and cleaning unit (flow meter and alarms). Although no chemical compounds are used or added to disinfect the ballast water, the effects of UV irradiation are categorised as the active substance.
