Oxygen VPSA Onsite Generator for Aquaculture - Agriculture - Aquaculture

OXYGEN VPSA INCREASES RAS FISH PRODUCTION AND REDUCES COST. WORLD CLASS POWER EFFICIENT & RELIABLE ONSITE OXYGEN VPSA. Oxygen is used in the RAS fish farm application to achieve maximum levels of dissolved oxygen (DO) to facilitate fastest fish growth and when combined with an ozone generator to achieve biological, odor and color control.

Adsorptech’s EcoGen™ model oxygen VPSA is the most cost effective and reliable source of oxygen for a RAS fish farm. The EcoGen™ is the most power efficient source of oxygen in the world – typical efficiency 0.245 kw/kg oxygen product at 1 barg and 0.277 kw/kg oxygen product at 3 barg. Globally, no other oxygen generating system can achieve the unique EcoGen™ reliability feature of running at half of its oxygen production rating when any process component on the front end (the silencer, blower, blower motor, VFD) is in need of maintenance, repair or replacement.

For low head oxygen injection and ozone production technology, the 15 psig (1 barg) EcoGen™ model will provide adequate oxygen delivery pressure. For traditional higher pressure RAS oxygen dissolution equipment, the 43 psig (3 barg) is used.

Globally, no other oxygen generating system can achieve the unique EcoGenTM reliability feature of running at half of its oxygen production rating when any process component on the front end (the silencer, blower, blower motor, VFD) is in need of maintenance, repair or replacement. For a typical RAS farm, the following EcoGen™ models should suit the farm’s need using a typical 0.17 kg feed/hr per 1 TPY fish farm capacity and an 80% oxygen dissolving efficiency.

  • 300 TPY ~ E20
  • 750 TPY ~ E40
  • 1100 TPY ~ E60
  • 1500 TPY ~ E80
  • 2200 TPY ~ E120
  • 3000 TPY ~ E160
  • 4000 TPY ~ E210
Oxygenation of Water and Water Purification

Oxygen is used directly in the potable water process and to make ozone to eliminate or reduce chlorine use, disinfect, control odor and taste, eliminate chlorine related byproducts, and oxidize pesticides. Oxygen is also used in flowing water or upstream of dams to maintain adequate levels of oxygen to sustain aquatic life.
