Ship's Ballast Water Analysis : Microfluidic Technology in Algae Analysis

The International Convention for the Control and Management of Ship's Ballast Water and Sediments mandates ships undertake ballast water treatment to reduce, remove or kill organisms of concern before being allowed to discharge their water. This book introduces technologies and devices that are used for the analysis of treated ballast water. Emphasis is placed on the separation, manipulation, detection, counting, and sizing of microalgae in a microfluidic chip which shows great potential for developing miniatured analysis devices.

Features:

• Introduces technologies and devices related to analysis of treated ballast water.
• Identifies the need for reliable devices to monitor viable organisms in treated ship’s ballast waters.
• Covers recent research in microfluidics-based cell sorting and developments of lab-on-chip devices.
• Addresses requirements of the Convention to be implemented by 2024.
• Reviews electric and optical-based methods for organism counting, sizing, and viability differentiation.

This book is aimed at researchers and professionals in marine engineering, ocean technology, environmental engineering, and microfluidics.
