Qingdao Headway Technology Co., Ltd., together with the Harbin Engineering University, proudly introduces OceanGuard™ BWMS. Its unique structure and reasonable design, stabilizes vessels during the drainage of Ballast Water, and poses no threat to marine life in surrounding waters thus protecting the marine ecology.

Shipping moves over 80% of the world's commodities and transfers approximately 3 to 5 billion tonnes of ballast water internationally each year.

Ballast water is absolutely essential to the safe and efficient operation of modern shipping, providing balance and stability to un-laden ships.

There are thousands of marine species that may be carried in ships' ballast water, basically anything that is small enough to pass through a ship's ballast water intake ports and pumps. If these organisms survive transport to other parts of the globe, their impact can be devastating. Such invasions can jeopardize the local ecosystem, and even pose threats to human health. Usually, their effects are irreversible.

The introduction of invasive marine species into new environments by ships' ballast water, attached to ships' hulls and via other vectors has been identified as one of the four greatest threats to the world's oceans. In 2004, IMO adopted the International Convention for the Control and Management of Ships' Ballast Water and Sediments, which will phase in requirements for ballast water treatment over the coming years.

IMO regulations will not affect all ships in the same way. Ballast water treatment will be phased in, with requirements for different ships arriving at different times.

In International Convention for the Control and Management of Ships' Ballast Water and Sediments, the following D-2 Regulation is addressed regarding management of ballast water.

Qingdao Headway Technology Co., Ltd., together with the Harbin Engineering University, proudly introduces OceanGuard™ Ballast Water Management System based on Advanced Oxidation Processes technology, in a brave attempt to solve the POLLUTION THREAT to the GLOBAL waters.

Advanced Oxidation Process technology (AOP), applied to destruction of organisms in water, destroys the organisms through an oxidative breakdown initiated by a powerful oxidizing species such as hydroxyl radicals.

With AOP, it is possible to oxidize a larger spectrum of compounds, by the highly reactive and unselective radical pathway than by direct ozonation. The generation of hydroxyl radicals (·OH) can be considerably intensified via various combination of oxidants, radiation and catalyst.

Hydroxyl radicals are extremely reactive and readily to attack most organic substances. As a result, the organisms are sequentially transformed to simpler organic molecules that are eventually mineralized to CO₂, H₂O and trace inorganic salt. The reaction rate constants between hydroxyl radicals and organic species are in the range of 10⁸-10¹⁰ M^-1S^-1 M. Hydroxyl radical typically reacts a million to a billion times faster than chemical oxidants such as ozone and hydrogen peroxide. In general, due to rapid hydroxyl-radical-based oxidation reactions, AOPs are characterized by high reaction rate and short treatment times.

Landbased testings of OceanGuard™ BWMS carried out in NIVA in Sept., 2009.

Shipboard testings carried out in MV “SITC YOKOHAMA” in Nov., 2009.

Data from Landbased testings and Shipboard testings indicate the fulfillment of the California requirements (SB497).

Control Unit
	The Control Unit is responsible for regulating the entire system including the monitoring of a variety of sensor signals, dealing with any alarm signals and automatically controlling system startup and shutdown sequences. The Control Unit includes all procedures needed for system operation, monitoring the system, including the working condition of various parts as well as the data and conditions reported by real time inspection from the various sensors.
EUT
	The EUT Unit, which is the core part of OceanGuard™, comprises two parts: Electro catalysis Unit and Ultrasonic Unit. The Electrocatalysis Unit is able to produce large number of Hydroxyl and other highly active oxidizing substances, and has a super long lifetime. The Ultrasonic Unit can produce a high intensity wave in a treated area instantly, killing biological material, including bacteria.
Filter
	OceanGuard™ fully automatic Backflush Filter has 50 microns precision filtration. The filter can accomplish both automatic backflush and filtering at the same time, removing any biological matter larger than 50 microns. It is able to prevent large-sized organism from entering ballst tank, so as to reduce the sediments inside.

• Energy- Saving and Economical

  Very low running cost for the operation of OceanGuard™. Only appr. 12 Kwh of electricity is needed for the treatment.of 1,000 tons ballast water.

Test Report for Corrosion Contrast Experiment for Water Treated by EUT Unit of OceanGuard™ BWMS to Different Materials and Coatings.

Based on the long-term testing , the effects of two test waters on Q235 steel, SS304 and coating materials are the same, indicating that the treated seawater will not change the corrosion rules in the natural seawater for the materials above; and for butyl rubber, the effects of treated seawater on its properties are less than that of natural seawater.
