Aquaculture & Water Purification

Clean, Safe Water for Fish and Humans

Oxygen is essential in creating and maintaining clean safe water.

  In aquaculture, the size of land-based Recirculating Aquaculture System (RAS) fish farms are increasing in scale exponentially. Historical farms were in the 300 to 1,000 tons per year (TPY) of fish production. RAS farms are now in the tens of thousands of TPY fish production. No longer does the traditional Liquid Oxygen (LOX) source of oxygen support sustainable cost or reliability. To reach and maintain maximum levels of dissolved oxygen (DO) to accelerate fish growth and lessen mortality, onsite oxygen production is critical to farm economics. Oxygen VPSA is the most economical and reliable oxygen source for large oxygen demands at and above 1,000 tpy of fish production requiring 150 kg per hour of oxygen and above. Adsorptech’s EcoGenâ„¢ oxygen VPSA is the only onsite production technology in the world that has built-in cost-effective redundancy thereby increasing reliability and lessening LOX backup consumption while maintaining economic sustainability. Oxygen feed to an ozone generator provides the most cost-effective means for biological, odor, and color control. The superior turndown capability maintains oxygen economics as the RAS farm demand changes over time.

  In potable water applications such as drinking water and large aquariums, oxygen enhances the efficiency of ozone generators achieving chlorine use and chlorine byproduct reduction, disinfection increase, oxidize pesticides, odor, and taste control. In steams or reservoirs, oxygen DO can be maintained at levels required to sustain life and prevent pollution.
