Shipboard Ballast Water Treatment Systems on Seagoing Ships

Transactions on Maritime Science, 2016
This review paper summarizes the legislative framework and the available technologies for ballast water treatment with regard to the approval process and relevant issues. The International Maritime Organization (IMO) sets the limits of organism concentration in ballast water allowed to be discharged into the sea.

THE PRECAUTIONARY PROCEDURES IN THE CASE OF NON-COMPLIANCE WITH THE BALLAST WATER MANAGEMENT CON-VENTION’S STANDARDS – POSSIBLE SOLUTIONS FOR POLISH PORTS

Contemporary Economy, 2016
On September 8, 2017 the International Convention for the Control and Manage-ment of Ships’ Ballast Water and Sediments (BWMC) adopted in 2004 will enter into force. It imposes a lot of requirements on shipowners and port states.

The Problem of Ballast Water in Montenegro Ports and Possibility of its Treatment

Polish Maritime Research, 2019
The problem of ballast water has been present in the world for the last hundred years, but it has grown and become more complex with the increasing intensity of overseas traffic. Introduction of various species from different parts of the world threatens

Assessing ballast treatment standards for effect on rate of establishment using a stochastic model of the green crab [PDF]

Computational Ecology and Software, 2012
This paper describes a stochastic model used to characterize the probability/risk of NIS establishment from ships' ballast water discharges. Establishment is defined as the existence of a sufficient number of individuals of a species to provide for a ...

Optimizing ballast water management: an evaluation of ballast water treatment system performance in challenging water conditions

Canadian Journal of Fisheries and Aquatic Sciences
The movement of ballast water is a major pathway for introducing aquatic invasive species. Ballast water management systems (BWMS) aim to reduce species introductions, but their performance varies under challenging water quality conditions. This study assessed BWMS performance in a freshwater port with impaired water quality by comparing harbour ...

Assessing the Performance of Shipboard Instruments Used to Monitor Total Residual Oxidants

Journal of Marine Science and Engineering
Shipboard ballast water management systems (BWMS) commonly employ chlorine or other oxidants to treat ballast. Oxidant-based BWMS inject these biocides to meet a concentration threshold or target value that is lethal to most aquatic organisms.

A Novel Ship-to-Shore Emergency Response System for Instantaneous Microbial Inactivation in Ballast Water

Journal of Marine Science and Engineering
To address the risks of cross-border transmission of pathogenic microorganisms posed by the failure or non-compliance of shipboard ballast water treatment systems, ports urgently require efficient and flexible emergency response solutions.

Computational Fluid Dynamics Analysis of Ballast Water Treatment System Design

Journal of Marine Science and Engineering
The effective management of ships’ ballast water is critical for preventing the spread of invasive species. Despite advancements in UV-based ballast water treatment systems (BWTSs), achieving a uniform flow distribution within UV reactors (UVRs) remains ...
