Research and development of ship ballast water treatment system

Abstract

If the ballast water is discharged without treatment, it will cause serious ecological damage to the local port. This paper takes the ship ballast water treatment system as the research object. The existing ballast water treatment system is investigated. A ship ballast water treatment system with capacity of 150m3 /h, filtration accuracy of 40um and UV dose of 350mJ/cm2 is designed. This paper introduces the working principle of the main unit of ship ballast water treatment system, and designs an automatic monitoring system based on PLC and LabVIEW. The results show that the device has high practicability and feasibility.
