Voyage data recorder (VDR)

A voyage data recorder (VDR), popular named black box is used for recording all kinds of navigation information

Types of treatment systems


Most ballast water treatment systems use a two-step process, usually mechanical filtration followed by disinfection.


Common methods include:


  • Filter and ultraviolet (UV): systems filter the particulates and bigger organisms followed by UV disinfection.
  • Filter and electrolysis: systems filter the particulates and the bigger organisms followed by injection of active substances1 generated from the electrolysis.
  • Filter and chemical injection: systems filter the particulates and the bigger organisms followed by injection of a chemical solution.
  • Ozone: disinfection through injection of O3.
  • Inert gas and ultrasonic: diffusing inert gas directly into the ballast tank to deoxygenate the water and using ultrasonic shockwaves to treat anaerobic organisms and bacteria.


Electrocatalysis Oxidation Technology


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.
