How much ozone at what rate and pressure should be added to a swimming pool capacity 625000 liters circulation of 171000 per hour?

According to the International Ozone Association (IOA), a typical ozone concentration for swimming pools is between 0.5 and 1.0 milligrams per liter (mg/L). In this case, we'll use a target ozone concentration of 0.8 mg/L.

Ozone Mass Calculation:

To determine the mass of ozone needed, we need to multiply the target ozone concentration by the total volume of water in the pool. The volume is provided as 625,000 liters, which is equivalent to 625 cubic meters (m³).

Mass of Ozone (mO₃) = Ozone Concentration * Volume of Water

mO₃ = 0.8 mg/L * 625,000 L

mO₃ = 500,000 mg = 0.5 kg

Ozone Flow Rate Calculation:

The ozone flow rate represents the amount of ozone that needs to be added to the pool water per hour. To calculate the required flow rate, we divide the mass of ozone by the circulation rate of the pool. The circulation rate is provided as 171000 L per hour, which is equivalent to 171 m³/h.

Ozone Flow Rate (FR) = Mass of Ozone / Circulation Rate

FR = 0.5 kg / 171 m³/h

FR ≈ 2.92 g/h

Ozone Pressure:

The pressure at which ozone is added to the pool water typically depends on the ozone generation system used. Ozone generators usually operate at pressures between 1 and 2 bar (100 and 200 kilopascals). To ensure safe and efficient ozone injection, it's essential to follow the recommendations and guidelines provided by the manufacturer of the ozone generator.

In summary, to maintain an ozone concentration of 0.8 mg/L in a swimming pool with a capacity of 625,000 liters and a circulation rate of 171,000 L per hour, an ozone mass of 0.5 kg should be added at a flow rate of approximately 2.92 g/h. The ozone pressure should be set according to the specifications of the ozone generator used.
