Vertex Aquatic Solutions recently announced the launch of oxygenation saturation technology (OST) to eliminate lake anoxia while preserving stratification. The side-stream saturation technology manages anoxia by pumping low dissolved oxygen water from a lake, canal or lagoon, saturate it with oxygen and return the water.
A ubiquitous characteristic of eutrophic lakes and reservoirs is oxygen demand in the bottom waters that exceeds available oxygen stored in the bottom waters during stratification. As a result, bottom waters remain anoxic for a significant portion of the year leading to nutrient recycling, harmful algae blooms, habitat loss, fish kills, odors and decline in water clarity. This method of OST of adding oxygen is quantifiable, allowing for any specified concentration of dissolved oxygen to be maintained based on water depth, temperature and salinity.
“At Vertex, we are always looking into innovation and new technologies to bring in new ways and enhanced solutions to our customers for their current needs,” Target Specialty Products president David Helt said. “We are pleased to announce that Vertex Aquatic Solutions, along with their partner, Gantzer Water, has developed a new oxygenation saturation technology, based on side-stream saturation technology.”
Vertex, a pond and lake products provider, focuses on bringing to market products that are environmentally sustainable and that enhance aquatic ecosystems and reduce chemical use.
“Vertex is excited to launch the release of the oxygen saturation technology,” said Patrick Goodwin, aquatic resource scientist for Vertex Aquatic Solutions. “This breakthrough technology is going to change the way we manage anoxia and improve lake water quality drastically.”
The new patented Vertex OST is equipped with a water pump specified for either freshwater or saltwater, oxygen dissolution chambers, bubble capturing system to off unwanted nitrogen, and plumbing. The system is designed to deliver the full capacity of oxygen generated at the lowest possible electrical cost. This high oxygen water is injected via an energy-dissipating header into the bottom waters of a lake or canal, where it will move through natural dispersion throughout the entire density layer. Injected oxygen behaves like coloring dye where it moves throughout the density layer shortly after injection. There are no bubbles made and no mixing to disturb bottom sediments or compromise the natural thermal structure of a lake. This system allows for greater oxygen concentration in water and at the sediment interface.
