1. The necessity of Ballast Water Management System: Threat Caused by Ballast Water

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. However, it may also pose serious threats to ecology, economy and health.
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.
2. Ballast Water Management System Treaty Requirements
Under the Convention, all ships in international traffic are required to manage their ballast water and sediments to a certain standard, according to a ship-specific ballast water management plan.     All ships  have to carry a ballast water record book and an international ballast water management certificate. The ballast water management standards are being phased in over a period of time. New ships must meet the ballast water treatment standard. Existing ships should exchange ballast water mid-ocean but they will need to meet the ballast water treatment standard by the date of a specified renewal survey. Eventually, most ships will need to install an on-board ballast water treatment system.
3. Components of Ballast Water Management System
(1)Control Unit
Control Unit is responsible for regulating the entire system including collection of various signals from the sensors, Management of alarm signals and controls of system startup and shutdown.  It contains all procedures for the system operation, displays the system working condition, including the working condition of various parts as well as data and status reported by real time inspection from various sensors.
(2)Filter
This device adopts full auto-back flushing filter, which can realize the simultaneous operation of filtration and back flush. The filtration precision is 50μm. It can remove organisms larger than 50μm in ballast water to prevent micro organisms and sediments entering ballast tank.
(3)EUT
EUT Unit is the core of this device. Each single unit has the treatment capacity from 100-3000m3/h. The Unit comprises of two parts: Electrocatalysis Unit and Ultrasound Unit. The Electrocatalysis Unit is able to produce large numbers of hydroxyl radicals and other highly active oxidizing substances to kill all organisms in ballast water within several nanoseconds. The whole sterilization process is completed inside the EUT Unit.  During the treatment process, the Ultrasound Unit can clean the surface of Electrocatalysis Unit regularly to keep the long-term treatment effectiveness of the electrocatalysis material.
4. Ballast Water Management System Advantages
(1)Technology of advanced electrocatalysis oxidation process (AEOP)
Hydroxyl radicals produced in the process of Management by AEOP technology will disappear after several nanoseconds. These radicals have high sterilization efficiency, which are able to kill different bacteria, viruses, algae and dormant ovum in ballast water effectively (broad spectrum sterilization) in a chained mode. The sterilization process can be completed within EUT Unit. The concentration of TRO (total residual oxidation) can be controlled within 2ppm, so that the TRO can carry out advanced Management on the water in ballast tanks.
(2)No corrosion to Ships
Hydroxyl radicals produced by Ballast Water Management System will disappear after several nanoseconds. The whole sterilization Management is completed within EUT Unit. Through the Management, TRO concentration is within 2ppm. According to results of long-term operation, the system is proved to be safe and reliable, and water treated by this device causes no corrosion to the hull.
(3)Compact design and high-quality spares
Compact design, small footprint, easy installation and maintenance free. Our device can be fitted on various vessels with different internal structures. High-quality materials and spare parts with long lifespan are used for all the components.
5. Ballast Water Management Several Class Certificates Supply:
ABS, BV, DNV, GL, KR, RINA, NK, USCG and CCS class certificates.
