Ballast Water Treatment System (BWTS)

Ballast Water Treatment System (BWTS) is designed to remove and destroy/inactive biological organisms from ballast water. There are three methods to treating ballast water; mechanical, physical or chemical. Mechanical methods would include separation and filtration; physical methods include ozone, electrical currents, or UV radiation, while chemical solutions are biocides or a form of chlorination. The BWMS convention aims to prevent the spread of harmful aquatic corganisms from one region to another and halt damage to the marine environment from ballast water discharge, by minimizing the uptake and subsequent discharge of sediments and organisms. Ferscom marine service specialized to integration of physical and chemical technology of BWTS (ballast water treatment system) into the fleets.

  Selection of ballast water treatment system

In order to comply with IMO BWMC and current USCG regulations regarding discharge of ballast water requires to be treated to prevent the spread of harmful living organisms at the port.The below listed characters to be considered to select the right technology.
