FlowCam^® - Flow Imaging Microscopy Blog

This year we introduced a new grant program for US and Canadian water utilities: The FlowCam Drinking Water Equipment and Travel Grant Program. The program is designed for water utilities to advance their science by helping them reduce labor hours, detect nuisance algae, and predict harmful algae blooms or taste & odor events.

One of the many reasons we at Fluid Imaging Technologies were excited to join the Yokogawa family of companies in 2020, is their commitment to sustainability and the environment.

The FlowCam was invented in the 1990s to study plankton in ocean water and quickly expanded its applications to drug development and life science. Our commitment to science and the health and safety of our planet and global community is the thread that has held our company together since its founding.

The American Water Works Association (AWWA) publication, Opflow, has featured another story this month on the benefits of proactive algae monitoring in eliminating taste and odor (T&O) complaints for water utilities. 

The cost of monitoring equipment can seem daunting and funding is not always attainable to small utilities. But solutions are available.

The FlowCam has been used in marine and freshwater applications since its invention in 1999. Since then, it has been found to be valuable across many industries to evaluate microparticles of importance in medicine, manufacturing, and environmental disciplines. Rarely do we see these applications cross paths - where man-made particles are being analyzed in marine and freshwater environments. One example of this intersection is the study of microplastics, and the problems they cause for our oceans and marine life. 

Have you ever wondered how our technical customer support team performs quality control checks during services and before shipping new instruments? Here's one example of the process our team uses to check for accuracy on the FlowCam Cyano.

An article featured this month in the American Water Works Association (AWWA) publication Opflow describes the challenges currently facing water utilities across the country, and lays out a strategy to proactively monitor for cyanobacteria and taste & odor causing algae.

"Most drinking water utilities enter high-alert mode upon testing positive for microcystin. Staff at the city of Wichita Falls, Texas, Water Purification Laboratory responded calmly when they received that dreaded phone call in July 2018 because of their progressive approach to monitoring cyanobacteria. Climate conditions are conducive to harmful algae blooms (HABs) and taste-and-odor events with increasing frequency and intensity. As a result, US Environmental Protection Agency (USEPA) regulations are moving toward requiring cyanobacteria monitoring. Proactive drinking water utilities are seeking a streamlined approach to monitoring cyanobacteria and nuisance algae." Adams et. al.

We are happy to announce that we have made available curated galleries of our favorite aquatic images from around the world, in a variety of applications. Are you curious what your water samples would look like when analyzed on the FlowCam? Check out all of the images in our galleries, or peruse below for a sampling of what's available. This is only a small sampling of what the FlowCam is capable of; please contact us if you'd like to see more.

Most organizations who are considering the purchase of a FlowCam ask themselves this question: how does the FlowCam compare to traditional light microscopy? They know that using a FlowCam is faster than using a microscope, and it's possible to produce larger amounts of data, but is the FlowCam as accurate?

Can it correctly calculate biomass, biovolume, and identify organisms? We don't want you to take our word for it, so we have gathered a selection of published studies that explore this very question. Please enjoy these summaries, and feel free to contact us for access to the full papers.

Based on proven FlowCam^® technology, the FlowCam Cyano automatically identifies cyanobacteria from other algae and particles in aquatic samples. Using a patent-pending combination of excitation wavelength, phycocyanin fluorescence measurement, and image recognition software, the system automates what was previously done using manual microscopy. After differentiating the cyanobacteria from the other algae in the sample, VisualSpreadsheet and Advanced Classifier software can be used to further characterize specific types of algae found in the sample using 40+ physical parameters.
