Ozone System

Dissolved ozone in water requirement (mg/L)

0.6

Ozone output calculation is according to whole swimming pool volume

Residual ozone in the air on swimming pool (mg/L)

≤0.2

Ozone System Calculation

 

- Ozone disinfection system is installed by-pass in the swimming pool, dissolved ozone in the water required 0.4-1.0mg/L.

EPA and OSHA according to the results, published in the swimming pool water of ozone disinfection system is CT value = 1.6. Contact time: ≤4mins.

- Ozone output calculation: 75 m3/hr x 0.6 mg/L = 45 g/hr

Recommend: model  FG-OF oxygen source ozone generator 50g/hr, Qty: 1 set


Corollary Equipment:

1 set of PVDF 2inch venturi injector

1 set of SUS backwater flow protection device

1 set of Ozone (water) reaction tank

1 set of Ozone destructor

1 set of Exhaust valve

 

Ozone Reaction Tank Calculation

 

- Ozone reaction tank selection: According to CT≥ 1.6 calculation, then T ≥ 3min ( T=1.6/0.6)

Ozone reaction tank volume : By-pass water flow rate (m3/h) * T = (75m3/hr * 40%) *3 /60 = 1.5 m3

Recommend: model FG-151200 ozone reaction tank:  DN1200mm, H1500mm, volume : 1.53m3, Qty: 1set

Reference

EPA and OSHA according to the results, published in the swimming pool water of ozone disinfection system is CT value = 1.6.

CT values are main design parameters of the ozone disinfection system, wherein C: represents the ozone concentration in mg / L ; T: representative of contact time, the count in min; CT values of both plot showing the effectiveness of the sterilization process.

For example, ozone concentration 0.4mg / L,  CT value is 1.6 , so contact time 4min. The higher the temperature, the shorter the response time, the lower the required CT value.

Some area with low CT values 0.8, ozone concentration of 0.2mg / L ~ 0.25mg / L, contact time 3.5min ~ 4min, in this case the amount of chlorine as an auxiliary disinfection can reduce 65%.When chlorine as a primary disinfectant and ozone as a disinfectant polishing, CT value may be less than 0.8, the ozone concentration is less than 0.5mg / L, the contact time is less than 1min.)
