RIEFILT RO-Umkehrosmoseanlage

RO 510-DT2-15S – Compact Seawater Reverse Osmosis System, approx. 15,000 l/day Potable Water

Compact, fully automatic reverse osmosis system for the production of hygienic drinking and process water from natural seawater. Ideal for maritime applications, island supply, hotels, small industrial and utility facilities.

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)
Feed Water: 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 µS/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)
Generally no chemical feed water pretreatment (no acid dosing) required
Hodpfsw Uf Ihsx Anpjw
Integrated rinse and CIP function, controlled via PLC
Skid-mounted on stainless steel frame (AISI 316)
High-pressure piping in stainless steel, low-pressure side in seawater-resistant plastic
Pump parts in contact with seawater made from corrosion-resistant materials

Operating & Energy Data

Feed Water Flow: approx. 1,000 l/h (reference value)
Operating Pressure RO Module: High pressure range, designed for seawater desalination
Power Connection: 230 V, 50 Hz, 1~
Power Rating: approx. 6 kW

Control, Monitoring & Safety

Local control panel with integrated PLC control
Monitoring of pressures, flows, conductivity, and operating hours
Automatic shutdown, including:
- Insufficient inlet pressure
- Exceeding the allowable operating pressure
- Overpressure in the permeate/concentrate line
- Exceeding defined conductivity limits (with automatic diversion to drain)
Automatic “Stop & Rinse” function: rinse of seawater-carrying components with permeate upon shutdown to reduce 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)

Typical Applications

Ships, offshore platforms, ports
Island and coastal supply
Hotels, resorts, small industrial and utility facilities
Backup or peak-load system for existing drinking water production
