The effects on phytoplankton from UV treatment systems is an area of concern as some methods may run into problems when trying to accurately estimate cell counts after UV treatment.  A detailed study by Bradie et al in Journal of Sea Research (2018) explored how well rapid indicative tools can estimate cell counts compared to microscopic analysis for the purpose of estimating phytoplankton cells after UV treatments in actual ballast water samples....

Application: Ballast Water Compliance Monitoring

In 2017 the Department of Land and Natural Resources (Division of Aquatic Resources), headed by Julie Kuo, finished testing a Ballast-Check 2 Handheld Fluorometer which is used for rapidly indicating if ballast water is within compliance levels set by D2 discharge standards. Results showed that the Ballast-Check 2, optimized for lower phytoplankton concentrations typically associated with ballast water, can rapidly and reliably measure 10-50 micron...

Turner Designs recently developed new data reporting software which ensures data integrity as requested by Saudi Aramco.  The new software writes Ballast-Check™ 2 results directly to a PDF report which cannot be altered.  Saudi Aramco is now able to ramp up their use of indicative compliance tools for collecting data from arriving ships. This data reporting software is included with all new Ballast-Check 2s and is available as a download for previously purchased units.
