The new KSB BWTS consists of an automatic back-flush filter, a low-pressure UV disinfection unit and a system control unit.

The automatic back-flush filter is available in two different variants: as a vertical cartridge filter and a proximity nozzle filter. A filter mesh size of 30 µm is used to reduce the amount of larger organisms. Thus sediment build-up in the ballast water tanks of the ships is minimised.

KSB reports that the control unit includes all the necessary functions for efficient operation of the system. It monitors parameters such as flow rate and pressure, provides an overview of the cycle in process and performs data logging for control by the port authority. The complete system with all components can even be installed on vessels with limited space.

Since the system works without any chemicals and no by-products are generated during the treatment, there is no need to store any hazardous chemicals on the ship.

The BWTS will be offered in different sizes and covers a range of 200-1000 m3 per hour.

KSB says shipboard testing will commence shortly.
