Ballast Water Treatment System from KSB Meets US Coast Guard Requirements
KSB, a German pump manufacturer and a leading manufacturer of pumps and valves throughout countries across the world, has developed a ballast water treatment system (BWTS). This new system has successfully completed a wide range of land-based tests that were specified specifically in the US Coast Guard’s (USCG) Environmental Technology Verification (ETV) test protocol.
The new KSB BWTS uses an automatic back-flush filter, a low-pressure UV disinfection unit, and a system control unit that all ensure the entire system runs efficiently.
Because KSB understands that these treatment systems will be used in a wide variety of applications, the automatic back-flush filter is available in two different variants that include a vertical cartridge filter and a proximity nozzle filter. The filter mesh size was addressed as well in order to minimize sediment build-up in the ballast water tanks of the ships. All filters have a mesh size of 30 µm.
According to the results of the tests run by KSB, the control unit in the BWTS includes all the necessary functions in order to run the system efficiently. It monitors multiple parameters that include flow rate and pressure, while overviewing the cycle in progress and performing data logging for control by the port authority. The complete treatment system can easily be installed on vessels with limited space.
One particularly important feature of the new system is that it works without any chemicals and no by-products, which means there is no need to store any hazardous chemicals on the ship.
Not only is the automatic back-flush filter available in multiple sizes, but the entire ballast water treatment system comes in different sizes that cover ranges of 200-1000 m3 per hour.
Now that initial tests have been completed, KSB will begin shipboard testing soon.
