Reverse Osmosis Systems: Complete Product Guide
Reverse osmosis (RO) is the gold standard for water purification — removing 95–99% of dissolved salts, heavy metals, bacteria, viruses, and organic compounds. WorldwideTradeX supplies four distinct RO series covering every application from residential kitchens to large-scale industrial production.
How Reverse Osmosis Works
RO forces water through a semi-permeable membrane under pressure (4–8 bar for brackish water, 55–70 bar for seawater). The membrane pore size (0.0001 microns) blocks dissolved contaminants while allowing pure water molecules to pass.
What RO removes:
- Dissolved salts and TDS (Total Dissolved Solids): 95–99%
- Heavy metals (lead, arsenic, chromium): >99%
- Nitrates and fluoride: 85–95%
- Bacteria and viruses: >99.9%
- Chlorine, pesticides, pharmaceuticals: >95%
- Hardness (calcium, magnesium): >98%
The Four RO Series
Omega Series — Compact Domestic RO
The Omega Series is designed for residential and light commercial use — under-sink installation with a dedicated faucet. Ideal for families seeking pure drinking water without bottled water costs.
System stages (5–7 stage):
- PP Sediment filter (5 micron) — removes sand, rust, sediment
- Granular Activated Carbon (GAC) — removes chlorine, odors
- Carbon Block (CTO) — fine chlorine and organic removal
- RO Membrane — core purification stage
- Post-carbon filter — final taste polishing
- (Optional) Alkaline/mineral filter — re-adds healthy minerals
- (Optional) UV sterilizer — total microbial control

| Power supply | 220V/50Hz |
| Control | Automatic (timer or flow-based) |
Best for: Hotels (in-house bottling), restaurants, food processing, laboratories, small industrial facilities.
Okta Series — Industrial High-Capacity RO
The Okta Series is engineered for large-scale industrial applications requiring continuous high-volume pure water production. Skid-mounted, fully automated, and designed for 24/7 operation.
System features:
- Multi-stage membrane arrays (8+ membranes per stage)
- Integrated pre-treatment: multimedia filter + softener + antiscalant dosing
- Energy recovery option for high-TDS feed water
- Full PLC automation with SCADA integration
- Remote monitoring and alarm management
- CIP (Clean-In-Place) system for membrane maintenance
| Parameter | Value |
|---|---|
| Production capacity | 5,000–500,000 L/day |
| TDS rejection | 97–99.5% |
| Recovery rate | 60–80% |
| Feed water TDS | Up to 10,000 ppm (brackish) |
| Operating pressure | 6–16 bar |
| Control | Full PLC + SCADA |
| Footprint | Skid-mounted, custom dimensions |
Best for: Industrial manufacturing, pharmaceutical production, food and beverage plants, hospitals, district water supply, hotel in-house bottling at scale.
Tankless (Direct-Flow) RO Systems
Traditional RO systems store purified water in a pressurized tank. Tankless (direct-flow) systems eliminate the tank entirely — water is purified on demand as you open the tap.
Advantages:
- Always fresh water — no stagnation in tank
- Faster flow rate (no waiting for tank to pressurize)
- Smaller footprint
- No tank membrane to replace
Best for: Modern kitchens, offices, and commercial installations where freshness and flow rate are priorities.
RO System Selection Guide
| Application | Recommended Series | Daily Capacity |
|---|---|---|
| Family home (4–6 people) | Omega | 100–200 L/day |
| Small restaurant / cafe | Compact | 200–400 L/day |
| Hotel (drinking water) | Beta | 1,000–3,000 L/day |
| Food processing plant | Okta | 10,000–100,000 L/day |
| Pharmaceutical production | Okta + EDI | 5,000–50,000 L/day |
| Industrial process water | Okta | Custom |
Pre-Treatment Requirements
RO membranes are sensitive to fouling and scaling. Proper pre-treatment is essential for membrane longevity:
| Feed Water Issue | Pre-Treatment Required |
|---|---|
| Chlorine present | Activated carbon filter |
| High turbidity (>1 NTU) | Sand or multimedia filter |
| High hardness (>300 mg/L) | Water softener or antiscalant dosing |
| Iron >0.1 mg/L | AS-Fe-Mn filter |
| Biological contamination | UV disinfection pre or post RO |
