FlowCam^® - Flow Imaging Microscopy Blog

The FlowCam's European partner and distributor, Anasysta, recently shared a story with Yokogawa about a local project that uses the FlowCam to monitor water quality in the River Stiemerbeek. 

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.

Researchers Karnan et al. have recently published the results of a study performed from 2013-14 in Estuarine, Coastal and Shelf Science. Their paper, titled "Implications of micro-plankton and micro-detritus on the food web in the largest monsoonal estuary along the west coast of India" tested the hypothesis that flooding would increase the quantity of available detritus in the Kochi Backwaters (KBW). 

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. 

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.

Tessa Rock, a junior at the University of New England (UNE), will be presenting her undergraduate FlowCam research at the New England Estuarine Research Society (NEERS) virtual fall meeting on Wednesday, October 21 as part of a session titled “Particles, Plants and Plastic”.

A long-term study undertaken by Chaffin et al. at Ohio State University monitored nutrient levels and phytoplankton growth in the Lake Erie central basin from 2014 until 2017. The purpose of the study was to determine the primary limiting nutrient determining phytoplankton growth, and determine if multiple limiting nutrients existed during this time period. The FlowCam was used to image and analyze phytoplankton species and to estimate biomass and biovolume of the species under consideration.

"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 very happy to announce the recipient of this year’s Aquatic FlowCam Research Equipment and Travel grant for undergraduate institutions. This grant provides students and professors with access to a FlowCam at their lab for the fall semester, as well as financial support to present their work involving the FlowCam at a North American conference (remotely, if needed).
