RIEFILT UF-RO-Meerwasserentsalzung mehrstufig

UF/RO Freshwater Generator 75 m³/Day – Seawater Desalination
RIEFILT UFRO 7100-7 ST06-75S

High-performance seawater desalination system for the production of up to 75 m³/day of hygienic drinking and process water from seawater (TDS up to approx. 40,000 mg/l). Compact, fully automated UF+RO unit mounted on stainless steel skid with proven Spacer-Tube® technology.

Applications

• Supply of coastal camps, construction sites, and service personnel
• Island and coastal communities, hotels & resorts (drinking and service water)
• Industry & power generation near the coast (chemicals, oil & gas, ports)
• Shipbuilding, shipyards, port logistics (central freshwater supply)
• Crisis and emergency response, NGO and military projects

This system excels wherever seawater is permanently available, but safe freshwater sources are lacking or too expensive.

Technical Concept & Advantages

• Ultrafiltration (UF) as robust pre-treatment in crossflow inside-out process
• High tolerance to pollutant loads, low fouling and clogging tendency
• Spacer Tube® RO modules with open feed channel, low differential pressure
• Excellent salt retention, low permeate salinity
• Post-treatment with deacidification filter and hardness stabilization to approx. 3 °dH
• Integrated CIP system, designed for 24/7 continuous operation with minimal operator input
• PLC control with automatic programs (start, rinsing, cleaning, preservation)
• Fully automatic monitoring of flow, pressure, temperature, and conductivity
• Automatic shutdown upon limit value exceedance (e.g., conductivity, pressure, dry-run)
