Zoos, aquariums and fish farms are utilizing oxygen systems
Buffalo, NY, February 1, 2020 – AirSep oxygen systems utilize its proven proprietary technologies to produce oxygen non-cryogenically. This technology uses an air separation process, Pressure Swing Adsorption (PSA), with molecular sieve (a synthetic zeolite), which attracts (adsorbs) nitrogen from air at high pressure and releases (desorbs) it at low pressure.

AirSep oxygen concentrators, generators, and oxygen plants use at least two vessels filled with molecular sieve as adsorbers. As compressed or pressurized air passes through one of the adsorbers, the molecular sieve adsorbs the nitrogen. This allows the remaining oxygen to pass through and exit the adsorber as a product gas. Before the adsorber becomes saturated with nitrogen, the inlet air flow switches to the next adsorber. The first adsorber is now regenerated by desorbing the nitrogen through depressurization back to the atmosphere, followed by an oxygen purge step. The complete cycle then repeats. When large-scale oxygen production is required, Vacuum Pressure Swing Adsorption (VPSA) is utilized. This process further aids the regeneration or desorption step utilizing a vacuum blower.

Oxygen plays an important role in a number of industries, including ozone generation and aquaculture, two applications that are widely used throughout North America.

Ozone creates clean water
Ozone is incorporated as part of water treatment processes in a variety of applications because ozone is an extremely effective disinfectant. For example, cleanwater is essential for animal health and reproduction, and in the case at AirSep’s residence in Buffalo, NY, The Buffalo Zoo utilizes ozone for disinfection of the water sources for animals.

Since 2008, AirSep PSA Oxygen Generators have supplied the feed gas to ozone generators at the polar bear, sea lion, and otter exhibits at the Buffalo Zoo. An AirSep packaged system, which includes two AS-D standard oxygen generators, helps ensure there is an excellent water source for polar bears to swim in. Six AirSep Topaz Plus self-contained units provide an attractive environment for sea lions. Oxygen and ozone work well together in purifying the water for these animals to create a clean and healthy environment.

Another wildlife facility that utilizes AirSep technology is the Georgia Aquarium in Atlanta. Two AS-N units generate the oxygen necessary for ozone production at approximately 1,300-1,600 SCFH of gas at 94% oxygen or higher. The ozone there is used as the primary disinfectant in many of their aquarium systems. Ozone is effective in removing bacteria, organics and pesticides, and oxygen aids in increasing the productivity and stocking density of the fish, which improves their overall health. Having a sufficient level of oxygen in the water benefits the growth of fish and reduces the mortality rate

Aquaculture, a large-scale commercial industry across Canada, is the science of farming fish, shellfish and other aquatic life (such as plants), in fresh water or saltwater. In St. John’s, NL, the Dr. Joe Brown Aquatic Research Building (JBARB) at the Memorial University of Newfoundland has an original AirSep system still in use (installed in 2004), an AS-45 (equivalent to the now available AirSep AS-B) and its main purpose is to produce oxygen for holding and maintaining the fish and shellfish. This large research and development center located by the (saltwater) ocean not only trains technical personnel, but also serves as an incubator unit for companies involved in the marine aquaculture industry and assists companies in commercial production of fish and shellfish. Danny Boyce, Facility and Business Manager, commented,” What I like most about the AirSep system is that it produces oxygen on its own, making it less expensive and more reliable.”

Buffalo, NY-based AirSep has been providing oxygen systems to a variety of industries since 1987 and has established a strong reputation for providing high-quality, easy-to-use systems with proven long-term reliability. In addition to eliminating the need for regular bulk deliveries, the numerous benefits of using AirSep Oxygen systems include:

  • Produce oxygen from an independent compressed air source
  • PLC process control
  • Highest process efficiency and low operating cost
  • Automatic and unattended operation
  • Touch-screen control panel with maintenance-free, solid-state purity monitor, including alarm and shutdown capability
  • Automatic and fail-safe backup options are available
  • Easy to install and maintain
  • Maximize ozone generator performance
  • Wide selection of systems and options

AirSep has a global presence with Oxygen Systems that are installed all over the world, even in remote locations or in underdeveloped areas with little or no infrastructure. They are perfect for users who require oxygen at a constant flow and pressure, 24 hours a day, 7 days a week. AirSep systems can increase business efficiency and free users from depending on large gas companies, their price increases, long-term gas contracts, and bulk deliveries. It is far safer and more reliable to generate gas on-site and as it’s needed. In addition, it’s also possible to achieve savings in areas including logistics, handling, operations, and safety.

AirSep’s product offering can be used in several other applications including, mining operations, environmental remediation, supplying medical oxygen to hospitals and medical facilities, gold leaching, and thermal/ chemical oxidation. AirSep’s broad portfolio of products has established the company as the undisputed leader in non-cryogenic on-site gas generation. Whether the application requires a self-contained generator, standard generator, packaged system, or a large plant, AirSep delivers innovative solutions for just about any oxygen generation requirement.
