📈 Calculated Ozone Requirements

Base Ozone Required: 11.4 g/hr
With Safety Factor Applied: 17.1 g/hr
With Additional Contaminants: 17.1 g/hr
Ozone Concentration Required: 7.1 mg/L

✅ Recommended Ozone Generator

15 - 20 g/hr

Based on your flow rate of 40 L/min and 11 ppm iron, we recommend an ozone generator with an output between 15-20 grams per hour. This provides adequate safety margin for complete iron oxidation.

Generator Size Range:
Min: 11.4 g/hr Rec: 15-20 g/hr Max: 28.5 g/hr

📋 System Requirements

Daily Ozone Production: 410.4 g/day
Venturi Gas Flow Required: 1.7 - 2.6 L/min
Minimum Contact Time: 2-4 minutes
Power Consumption Estimate: 205-256 Watts

Calculation Steps:

1. Convert flow to m³/h: 40 L/min × 60 ÷ 1000 = 2.4 m³/h

2. Ozone dosage needed: 11 ppm × 0.43 = 4.73 ppm (g/m³)

3. Base ozone required: 2.4 m³/h × 4.73 g/m³ = 11.4 g/h

4. With safety factor (1.5): 11.4 × 1.5 = 17.1 g/h

*Ozone demand factor of 0.43 mg ozone per mg iron is based on standard oxidation stoichiometry

💡 Pro Tips:
  • Choose a generator rated 20-30% higher than your calculated needs for reliability
  • Ensure all components downstream are ozone-resistant (Viton, PTFE, stainless steel)
  • Consider a dissolved ozone monitor for precise control
  • Venturi injectors typically require 5-15 psi pressure differential
