Teaming with stakeholders including customers, regulators, scientists and government departments, Hyde pioneered the application of mechanical separation and UV disinfection as being a ballast water management solution at fivergroup.com. After a few years of land-based and shipboard prototype testing and lessons learned, the Hyde GUARDIAN® (HG) emerged in 2003.
The HG includes an auto-back flushing filter which removes sediment and larger plankton, and also a powerful medium pressure UV disinfection system which destroys or inactivates small organisms and bacteria. Such systems can easily be built-into the ship's ballast control system and, for the low pressure drop modifications to existing ballast pumps are certainly not required.
In the sequential method, the ballast tanks were made to be run before pumps lose suction and stripping arrangements are used. The Chief Engineer Officer must render full co-operation which is a critical operation for your pumps. In ballast pumps with gland packing stuffing boxes, the gland packing can overheat on account of unavailability of cooling and lubricating water. In ballast pumps with mechanical seals, the mechanical seals is usually damaged because of overheating caused by a shortage of cooling and lubricating water. The Chief Engineer Officer must instruct every one of the junior engineers and subordinates about the same and make certain compliance while protecting the pumps. Effective watch out and watch needs to be posted close to the pumps.
The quartz sleeve and power assemblies were designed for fast and simple removal in the UV Sterilizer body. You can take off the entire assembly with a few twists for or you can easily replace the UV Lamp without disrupting the stream flow by solely detaching the power assembly. The connections are watertight and many types of seals are 12 months.More information check this link
