Development of Methods for Biological Injection and Sampling from Fluid Lines
Abstract
A critical factor in providing consistent and accurate organism loads to test ballast water treatment equipment is the injection of surrogate organisms. Additionally, it is necessary to acquire representative samples from flowing pipes to assess the treatments effects on the number and viability of organisms. As a result of the interaction between mechanical processes and living organisms, there are inevitably both mortality and recovery issues. The current document presents data and a discussion regarding the design, construction, operation and relative performance of various types of pumps for inserting Artemia into flowing seawater pipes eight inches in diameter. The effects of several sampling configurations on organism viability and recovery are documented. These include both assemblies for obtaining continuous samples from flowing pipes and configurations for receiving, holding, and concentrating samples. The effect of analysis time on organism viability and recovery is also discussed. Recommendations are made for the best injection, sampling, and holding configurations.
