Hyde Marine, Inc. announced that its Hyde GUARDIAN ballast water treatment system (BWTS) received Type Approval from the American Bureau of Shipping (ABS).
The GUARDIAN features a two- stage process; an efficient depth filter to remove sediment and larger organisms, and a powerful UV disinfection unit to kill or inactivate smaller plankton, bacteria and other pathogens.
The flexible, modular design of the GUARDIAN allows it to be installed in even the most crowded machinery spaces. The filtration system can be delivered in small modules to be configured in a variety of shapes to fit available space. The Hyde GUARDIAN system is designed for minimum pressure drop, allowing use of existing ballast pumps. The modest energy consumption of the UV system in most cases allows installation of the system without major upgrades to the electrical generating and distribution system. Interface with the existing ballast system is simple and many installations are completed without requiring drydock and even while the vessel is in commercial operation.
The Hyde GUARDIAN system is fully integrated into the ship’s control and automation system. During ballasting, water is processed through both the filter and UV stages as it is pumped from the sea chest to the ballast tanks. All solids and organisms captured by the filters are discharged during backflushing to the location they entered. During de-ballasting, the filter is bypassed and water flows only through the UV system before discharging overboard. Hyde GUARDIAN system and ballast operation data are automatically logged. Hyde can advise clients on the design and installation of water sampling ports in accordance with IMO G2 Guidelines.
