Reverse osmosis
What Is Reverse Osmosis?
Reverse osmosis (RO) is a water purification process that uses a semi-permeable membrane to remove ions, molecules, and larger particles from drinking water. This advanced filtration technology ensures clean, safe, and great-tasting water for your home or business.
How Does Reverse Osmosis Work?
Our reverse osmosis systems work through multiple stages of filtration:
- Pre-Filtration: Removes sediment, chlorine, and large particles
- RO Membrane: The heart of the system that removes up to 99% of contaminants
- Post-Filtration: Polishes water taste with activated carbon
- Storage Tank: Holds purified water until needed
- Final Filtration: Optional UV or remineralization stage
Reverse Osmosis System Specifications
| Model | Filtration Stages | Daily Capacity | Contaminant Removal | Membrane Life |
|---|---|---|---|---|
| RO-300 | 5 | 300 gallons | 99% | 2-3 years |
| RO-500 | 6 | 500 gallons | 99.5% | 3-5 years |
| RO-800 | 7 | 800 gallons | 99.9% | 5+ years |

Reverse Osmosis FAQ
How often should I replace reverse osmosis filters?
Pre-filters should be replaced every 6-12 months, the RO membrane every 2-3 years, and post-filters annually. However, replacement frequency depends on your water quality and usage. Our systems include filter change indicators and most models feature quick-change cartridges for easy maintenance.
Does reverse osmosis remove healthy minerals from water?
While reverse osmosis does remove some beneficial minerals along with contaminants, our premium models include a remineralization stage that adds back essential minerals like calcium and magnesium for better taste and health benefits. Alternatively, you can obtain these minerals from a balanced diet.
Why is my reverse osmosis system producing less water?
Reduced water production could indicate several issues: a clogged pre-filter, low water pressure (should be 40-80 psi), a fouled RO membrane, or cold water temperatures slowing the process. First check and replace your pre-filters, then verify your water pressure. If problems persist, our technical support team can help diagnose the issue.
Contaminants Removed by Reverse Osmosis
| Contaminant Type | Removal Rate | Examples |
|---|---|---|
| Heavy Metals | 95-99% | Lead, Mercury, Arsenic, Chromium |
| Dissolved Salts | 90-99% | Sodium, Fluoride, Nitrates |
| Microorganisms | 99.9% | Bacteria, Viruses (with optional UV stage) |
| Organic Compounds | 98% | Pesticides, Herbicides, VOCs |
Installation and Maintenance
Our reverse osmosis systems come with comprehensive installation guides and most homeowners can complete setup in 1-2 hours with basic tools. Professional installation is available through our network of certified plumbers. Maintenance involves simple filter changes and periodic sanitization - we provide detailed schedules with each system.
