Aquaculture Water Treatment: Why Use UV?

The aquaculture industry relies on the quality of water used to incubate fish eggs and rear juvenile fish. Water abundance and purity continue to decrease, while disease concerns found in source waters continues to increase. Aquaculture water treatment has remained a valuable tool in addressing these concerns.

This phenomenon is due in part to the increased demand for water from growing urban areas, continued pollution of our natural waters and the introduction of new, pathogenic microorganisms to natural waters through a variety of routes: bird, animal and human activities, including ballast water discharge. This brings many challenges to a rapidly growing industry.


How do I Mitigate These problems?

There are solutions available today which can help to overcome them. Increasingly, fish hatcheries and rearing facilities are evaluating ways to improve the quality of their source water, while off-setting quantity losses through the implementation of recirculating water systems.

This is leading more fish hatcheries to install sophisticated water treatment systems.
Systems designed to:

  • Enhance overall water quality
  • Reduce the possibility of disease outbreaks due to pathogens
  • Balance water needs due to the lack of available water from natural sources.

Ultraviolet (UV) light disinfection systems play an important role in a complete water treatment process in aquaculture facilities. System designs are available in both closed vessel and open channel arrangements to provide the greatest flexibility to the hatchery, and components have evolved over time to provide some of the most reliably performing and easy-to-operate technology in aquaculture water treatment applications. Additionally, we offer UV systems for well boats that are ultra-compact for those tight spaces.

UV systems significantly reduce pathogen counts in incubation and rearing facilities and have proven to be the most cost effective disinfection technology for the inactivation of various types of bacteria, viruses and parasites harmful to many species of fish.

Residual Ozone Destruction

Ozone is often used in a fish hatchery to enhance the quality of problematic water sources used for incubating and rearing fish. However, residual ozone in the water can be extremely toxic or fatal to the aquatic life being reared. To ensure that the fish are not exposed to residual ozone, there are often one of two removal processes employed. The first is an ozone off-gassing column which vents ozone to atmosphere; this may not be the best design based on its toxic effect to the environment. The second method is applying 254nm UV energy to consume the residual ozone in the bulk water prior to contacting the fish.
