How to Choose Between Single & Double RO Systems for Cosmetic Production?
Cosmetic Grade Pure Water Equipment (Reverse Osmosis RO Technology)
🔹 Why does the cosmetics industry need RO pure water equipment?
• Ordinary water contains impurities (minerals, microorganisms) that may affect the stability of cosmetics.
• High-purity water ensures product safety and extends shelf life.
• Industry standards (such as GMP, ISO) require high water quality.
🔹 How Does Reverse Osmosis (RO) Technology Work?
• Principle: High pressure drives water molecules through a semi-permeable membrane, blocking 99% of impurities
• Substances Removed: Salts, bacteria, viruses, colloids, organic matter
• Desalination Rate: 97%-99% (single-stage RO), >99% (two-stage RO)
🔹 Single-stage RO vs. two-stage RO: How to choose?
| Comparison Items | Single-stage Reverse Osmosis | Two-stage Reverse Osmosis |
|---|---|---|
| Desalination Rate | 97%-99% | >99% |
| Resistivity | 0.05-0.5 MΩ/cm | 0.5-1 MΩ/cm |
| Application Scenarios | Basic cosmetics production | High-end skincare products, injectable-grade products |
🔹 The 5 core advantages of RO pure water equipment
✅ Ultra-high filtration precision (0.0001 microns, blocks 99% of contaminants)
✅ No chemical additives (pure physical filtration, safe and pollution-free)
✅ Energy-efficient and high-performance (low energy consumption, high output)
✅ Modular design (scalable, adapts to different production capacities)
✅ Complies with international standards (FDA, GMP certified)
🔹 How to Choose the Right Cosmetic RO Pure Water Equipment?
• Considerations: Water quality requirements, production scale, budget
• Customized Solutions: Adjusted based on product type (skincare products, shampoo, serums, etc.)
• Maintenance Costs: Membrane replacement cycle, energy consumption, automation level
🔹 Frequently Asked Questions (FAQ) ❓
Q1: Can RO pure water equipment remove bacteria?
→ Yes, RO membranes can filter out 99.9% of bacteria and viruses.
Q2: Which is more cost-effective, single-stage RO or dual-stage RO?
→ Single-stage RO is suitable for general cosmetics, while dual-stage RO is suitable for high-end/medical-grade products.
Q3: Are the operating costs of the equipment high?
→ In the long term, RO is more economical than distillation/ion exchange.
