EcoBallast is a Ballast Water Treatment System developed by Hyundai Heavy Industries Co., Ltd. (HHI) and Hyundai Welding Co., Ltd. is an authorized OEM company of HHI BWTS and covers sales, design, fabrication, commissioning, and training. EcoBallast is based on filtration and ultraviolet irradiation technologies, and it is composed of major equipment such as filter, UV reactor, CIP (Cleaning in Place), and system control unit.
The filter can significantly reduce the number of suspended solids in the ballast water and prevent the ingress of marine organisms bigger than 50μm into ballast tanks.
The UV reactor is specially designed for EcoBallast to reduce its installation space and to maximize its treatment efficiency, which employs a high-intensity, medium-pressure ultraviolet lamp.
For complete Ballast water treatment, the ballast water is treated at intake (ballasting) and once again at discharge (de-ballasting). In other words, the additional ballast water treatment is performed during deballasting in order to prevent the proliferation of marine organisms in the treated seawater during ballasting.
The CIP (Cleaning in-place) unit is an automatic cleaning device that cleans the quartz sleeves covering the UV-lamps after each ballasting or de-ballasting operation. It operates to prevent the degradation of UV lamps due to marine contaminants.
