their core business. SM ALL S PA C E AND EA S E O F
IN S TALLATION 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.

S Y S TE M 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 seachest 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 by the system and water sampling ports are installed in accordance with IMO
G2 Guidelines. INLET OUTLET

## T H E F I L T E R S O L U T I O N

Ballast water is a particularly challenging filtration application due to the constantly changing biological and sediment loading, the corrosive nature of seawater, and the high flow required compared to power and space available. After years of testing different filter technologies for ballast water treatment, Hyde selected a unique stacked-disk filtration system as the standard for the Hyde GUARDIAN. This technology combines performance and efficiency of a depth filter with reliable automatic backflushing capability superior to that of a barrier filter.
Other important benefits include corrosion-free materials of construction, low pressure drop, ability to handle heavy sediment loading, low maintenance requirements, and modular design that allows flexibility to install in existing machinery spaces.

Filtration The automatic backflushing filter ensures reliable removal of solids and larger organisms.The filter contains several modules of “stackeddisk” filter elements that capture and store large amounts of solids. The filter is designed to automatically backflush itself at the end of each ballasting operation and, when necessary, clean one module at a time using filtered water from the remaining modules. This allows for continuous ballast flow and immediate discharge of the filtered material back into the ballast water source.

T he Sta c ked- D i s k Filter D e s i g n Thin nylon disks are diagonally grooved on both sides to a specific micron size. These

disks are stacked and compressed on special spines to create filter elements. The grooves on top of each disk run opposite to the grooves below, forming

a statistically significant series of valleys and traps for solids. As water flows from the outside of each element to the core, the intersections of the grooves form dozens of stopping points in each

flow path, thus creating an efficient depth filter to capture solids.

The stacked-disk elements are enclosed in a corrosion and pressure resistant housing module with a number of modules assembled in the system to provide the desired capacity. What makes this filter design so special is how it is cleaned. During filtration the disks are tightly compressed together by spring and differential pressure. When a preset pressure differential is reached, a patented backflushing process quickly and efficiently cleans the entire module, while creating a small total backflush volume. The first step in the backwash cycle is to activate the 3-way valve, which closes the inlet and opens the drain. By removing the differential pressure in the system, the spine piston rises up releasing the compression on the disks. Tangential jets of clean water are pumped at high pressure in the opposite direction through nozzles at the center of the spine. The disks spin free and clear, loosening the trapped solids. Solids are quickly and efficiently flushed out through the drain and immediately overboard. As this water contains only organisms that were recently picked up, they are simply being returned to the environment from which they came. Each module, with five to eight stacked disk elements, is completely cleaned in 10 to 20 seconds. The backflush process is repeated with each module until the entire filtration system is clean. This automatic backwashing ensures that the system operates reliably and with minimal reduction of ballast water flow.

Sizin g The filter systems used in the different Hyde GUARDIAN systems are sized to provide an efficient filtration of the total required ballast water flow. The chart below shows the maximum allowable flow for each filter module size in the Hyde GUARDIAN range. When sizing and choosing the correct filter system for each customer, the filtration capacity selected is always at least one unit higher than the required ballast water flow rate.

The Hyde GUARDIAN uses a high intensity ultraviolet (UV) treatment as a means of disinfection. The UV chamber is carefully designed for minimum pressure drop, maximum retention time, and compatibility with the marine operating environment. UV dosage is a combination of lamp power, UV transmission, distance from the lamp sleeves, and exposure time. The flow velocity through the UV chamber is optimized to be within the range of 0.5 m/s to 3.0 m/s. The advantages of using UV rather than chemical disinfection include:

• UV runs automatically with very little operator attention

• UV does not contribute to corrosion like chemical oxidants

• UV does not require transportation, storage or handling of hazardous material

• UV requires minimal space for chemical storage equipment and contact chamber

• UV has no danger of overdosing

• Organisms cannot build resistance against UV

• UV does not require dilution or deactivation

• UV has no known toxic or significant nontoxic by-products

• UV is 100% safe without side effects U V L i g ht Ultraviolet light is the part of the electromagnetic spectrum just below the visible portion and it can be further broken down into four smaller bands:

• UV-A 315nm-400nm

• UV-B 280nm-315nm

• UV-C 200nm-280nm

• UV-Vac 10nm-200nm The portion that is known as germicidal is the region of UV-C from 240-280nm, with a peak at 264nm. UV-C light deactivates or damages the DNA of organisms, killing them or making them unable to reproduce. UV light is produced using mercury vapor lamps. There are two basic types of UV lamp technology. The first is called a low pressure lamp. It excites the mercury molecules to a relatively low level resulting in a monochromatic output at 254nm. The medium pressure lamps that the Hyde GUARDIAN utilizes produce a polychromatic output across the entire spectrum of the germicidal curve. The relative germicidal effectiveness is shown on the diagram at right. The UV lamps used in the Hyde GUARDIAN have an expected service life of 8000 hours, which is far superior to other lamp types.

T reat m ent Cha mb er The Hyde GUARDIAN UV system includes a specific number and size of UV lamps depending on the total ballast water flow to be treated. These lamps are housed in high quality quartz sleeves, which pass through the corrosion resistant treatment chamber. The system employs an automatic wiping mechanism to keep deposits from accumulating on the sleeves. In addition there is a temperature sensor to monitor water temperature, a UV sensor to measure the relative intensity of the UV lamps, a drain, and air relief valves. For routine checks, maintenance and replacement of the quartz sleeves and wipers, the chamber has an inspection and access hatch. Sizin g The UV treatment system in each Hyde GUARDIAN model is sized to provide a minimum average dose, at maximum rated ballast flow, at the end of the lamp life. Sizing is according to the chart below.

* Maximum power is typically only drawn when the system is in the highest power level, during the last 1⁄4 of the

lamp’s life or when UV transmission is low due to exceptionally poor ballast water quality. 161235	 201235	 201835	 201850
