The FRO-CDual-1000 represents a breakthrough in scalable water treatment architecture, delivering 1,000 m³/day (264,000 GPD) of high-quality permeate through two interconnected 40ft ISO container modules operating in parallel configuration. This twin-module design fundamentally reimagines large-capacity containerized water treatment by providing inherent N+1 redundancy, enabling individual module isolation for maintenance without interrupting water production, and offering a clear path for incremental capacity expansion without the capital intensity of single large-scale plants.

• Twin-Module N+1 Redundancy: Two identical 500 m³/day containerized RO trains operate in parallel through a common feed manifold and permeate collection header, ensuring continuous water production during maintenance or unexpected shutdowns.
• Centralized SCADA with Distributed PLCs: Each module features its own S7-1200 PLC with a central master SCADA controller providing unified operator interface through a 15-inch HMI workstation.
• 42 Premium Membranes per Module: Each 500 m³/day module incorporates 42 DOW Filmtec BW30-8040 membrane elements configured in an optimized 3-stage array, providing exceptional salt rejection performance exceeding 99%.
• Independent Module Isolation Valving: Dedicated automated butterfly valves enable complete hydraulic isolation of any single module in under 30 seconds via SCADA interface.
• Grundfos CRN VFD Pump per Module: Both modules are equipped with independent Grundfos CRN series SS316L vertical multi-stage pumps with dedicated variable frequency drives.
• Synchronized Chemical Dosing Systems: Independent anti-scalant, sodium bisulfite, and sodium hydroxide dosing pumps with centralized chemical storage for efficient resupply logistics.
• Scalable Expansion Architecture: Pre-configured to accommodate up to two additional 500 m³/day modules, enabling future expansion to 2,000 m³/day total capacity.

The FRO-CDual-1000 is purpose-designed for water treatment applications where reliability, scalability, and operational continuity are equally critical. Primary deployment scenarios include municipal water supply systems serving cities with populations of 30,000 to 60,000, regional desalination plants, mining and mineral processing operations, large-scale food and beverage manufacturing facilities, and power generation plants. The modular architecture provides significant advantages for project financing, allowing capital expenditure to be phased across the commissioning timeline without sacrificing initial production capacity.

Each FRO-CDual-1000 twin-module system undergoes sequential factory acceptance testing including individual module wet testing at 500 m³/day for 48 hours, followed by integrated system testing with both modules operating in parallel for an additional 24 hours. Both containers ship as standard ISO units with full CSC certification. The comprehensive documentation package includes system-level P&ID, electrical single-line diagrams, O&M manuals, integrated system commissioning procedures, and recommended spare parts inventory. Optional services include on-site installation supervision, integrated system commissioning, operator training programs, and long-term service agreements.
