An interesting field of UV use is for depuration.   Depuration plants have been one of the longest users of UV.  Bivalve shellfish can become contaminated from the waters in which they are raised. Contaminated shellfish can harm humans when they are consumed. Health risks increase because shellfish are often eaten raw or lightly cooked.   Health risks are dependent on where the shellfish are raised and level of contaminants in those water bodies.

The depuration (purification) is a process whereby after shellfish are harvested they are placed in tanks of clean re-circulating seawater under conditions which maximize their natural filtering activity which results in expulsion of intestinal contents, which enhances separation of the expelled contaminants from the bivalves, and which prevents their recontamination. Depuration plants came about due to shellfish outbreaks of typhoid (Salmonella typhi) at the end of the 19th century and the beginnings of the 20th century with raw shellfish consumption was popular.

“Depuration is effective in removing many bacterial contaminants from shellfish. As currently commercially practised, it is less effective at removing viral contaminants such as norovirus and hepatitis A. It is not consistently effective, or is ineffective, in removing other contaminants such as naturally occurring marine vibrios (e.g. Vibrio parahaemolyticus and Vibrio vulnificus), marine biotoxins (such as those causing paralytic shellfish poisoning PSP, diarrhetic shellfish poisoning DSP and amnesic shellfish poisoning ASP) or heavy metals or organic chemicals.”   Lee, R.; Lovatelli, A.; Ababouch, L.

The systems are designed with UV lamps to disinfect aquaculture and fish environment water supplies. For over 30 years, Glasco UV has been working with private, federal, state and other governmental hatcheries.  Applications include fish farms, fish hatcheries, depuration plants, aquariums and other aquaculture facilities that need UV disinfection technology.

Systems are scalable and available with many options including PLC controls for integration into facility network.   UV fish systems are designed in a variety of configurations.  From closed pressure vessels to vertical or horizontal open channels and are designed to treat both fresh and seawater. Systems are manufactured from stainless steel and from PVC for aggressive waters.

UV disinfection works well on a wide array of water borne pathogens.  Many of the projects we work on relate to seafood.   Salmon, trout, oysters and clams make up the largest percentage of our work.  There are specific pathogens that are of concern in these markets. The pathogens fall into the following groups: Bacteria, Virus, Algae, Protozoa and Fungi.   Some are easily disabled using low dosages of UV light.   Many require much higher doses.  For example, most drinking water related pathogens require UV doses of 40 mJ.   Some drinking water pathogens like Adenovirus require 186 mJ.   For aquatic & fish waters, we see similar dosages being required.  However, the most serious virus, Infectious Pancreatic Necrosis Virus (IPNV) requires a UV dosage of 246 mJ/cm2.Type your paragraph here.


Glasco UV works with governmental agencies like the National Oceanic and Atmospheric Administration (NOAA).  NOAA Fisheries are “responsible for the stewardship of the nation's ocean resources and their habitat. They provide vital services for the nation: productive and sustainable fisheries, safe sources of seafood, the recovery and conservation of protected resources, and healthy ecosystems—all backed by sound science and an ecosystem-based approach to management.”

NOAA says that “U.S. fisheries are among the world’s largest and most sustainable. Seafood harvested from U.S. federally managed fisheries is inherently sustainable as a result of the U.S. fishery management process. Using the Magnuson-Stevens Act as the guide, NOAA Fisheries works in partnership with Regional Fishery Management Councils to assess and predict the status of fish stocks, set catch limits, ensure compliance with fisheries regulations, and reduce bycatch.”
