RIEFILT RO-Umkehrosmoseanlage

RO 510-DT2-15S – Compact Seawater Reverse Osmosis System, Approx. 15,000 L/Day Drinking Water

Compact, fully automated reverse osmosis unit for producing hygienic drinking and process water from natural seawater. Ideal for maritime applications, island supply, hotels, smaller industrial, and utility operations.

Technical Specifications

Type: RO 510-DT2-15S

Process: Reverse osmosis with Disc-Tube (DT) technology

Permeate output: Approx. 15,000 L/day (15 m³/day, depending on operating conditions)

Feedwater: Seawater with high conductivity, approx. 55,000 µS/cm (high salt content)

Permeate quality: Drinking water, approx. 500 mg/L residual minerals (reference value)

Recovery rate: Approx. 30% (typical operating range) at 55,000 µm/cm conductivity

Design temperature: Approx. 25 °C (operating range approx. −2 to 35 °C)

Process Technology & Construction

- DT module with open feed channel – highly fouling-tolerant and fully cleanable
- Mechanical pre-filtration (high-performance filter + 10 µm cartridge filter)
- Typically no chemical feedwater pre-treatment required (no acid dosing)
- Integrated flush and CIP function, PLC-controlled
- Skid mounting on stainless steel frame (AISI 316)
- High-pressure lines in stainless steel, low-pressure section in seawater-resistant plastic
- Pump parts in contact with seawater made of corrosion-resistant materials

Operation & Power Data

Feedwater flow: Approx. 1,000 L/h (reference value)

Operating pressure RO module: High pressure range, designed for seawater desalination

Power supply: 230 V, 50 Hz, 1~

Connected load: Approx. 6 kW

Control, Monitoring & Safety

- Local operator panel with integrated PLC control
- Monitoring of pressures, flows, conductivity, and operating hours
- Automatic shutdown including:
- Insufficient feed pressure
- Exceeding permissible operating pressure
- Overpressure in permeate/concentrate lines
- Exceeding defined conductivity limits (with automatic diversion to drain)
- Automatic “Stop & Rinse” function: Flushes seawater-contacted components with permeate during shutdown to minimize fouling during idle periods

Dimensions & Weight (Skid)

L × W × H: approx. 1,190 × 705 × 1,500 mm

Weight: approx. 530 kg (dry), approx. 605 kg (in operation)
