Using the O2Zone
Even with elevated oxygen purity and increased spray chamber pressure, the O2Zone® is not able to reach the theoretical oxygen saturation during the few seconds that the gas is in contact with water. In addition, water entering the spray chamber is never pure water and already contains dissolved gases other than oxygen – primarily nitrogen and argon. Hence, a much longer contact time and degassing of the water supply would be required to saturate the water with oxygen. Degassing systems and long contact times are not practical for a compact and easily operated oxygenation system. In spite of these limitations the O2Zone® achieves impressive results when compared to aeration.Typical oxygen concentrations for treated ground water at 10° Celsius range from 30 to 45 mg/L depending on water flow rates and spray nozzle pressures. In most cases the gas-liquid contactor (GLC) operates most efficiently near the maximum system flow rate and with the spray nozzle operating at a higher pressure and producing a smaller water droplet size. Increases in chamber pressure tend to increase DO concentrations but above 10 psig (24.69 psia) the increase in concentration is nominal.
