OEM Ultra Pure Reverse Osmosis Purified Water Suppliers & Manufacturers

To provide an engineered proposal and projection, our process design team requires a comprehensive raw water analysis report detailing Total Dissolved Solids (TDS), electrical conductivity, pH, total hardness, reactive silica, free chlorine, iron/manganese levels, and Silt Density Index (SDI) or turbidity. In addition, you should specify target output capacity (m³/h or GPD), product water purity (resistivity in MΩ·cm or conductivity in µS/cm), daily duty cycle, plant operating temperature range, site power specifications (e.g., 380V/480V 3-phase 50/60Hz), and preferred footprint (skid mounted vs. weatherproof ISO shipping container).

Achieving theoretical ultra-pure water quality requires an integrated multi-barrier treatment train. We combine multimedia filtration, activated carbon, and antiscalant dosing with a primary double-pass reverse osmosis (DPRO) setup to reject 99.5%+ of ionic and dissolved organics. The permeate passes through a gas-permeable deoxygenation membrane contactor to remove dissolved CO2 and O2, followed by continuous electrodeionization (EDI) to remove weak ions and reactive silica. For sub-ppb semiconductor requirements, the polishing loop integrates 185nm TOC destruction UV lamps, dual non-regenerable nuclear-grade mixed-bed polishers, and 0.05 µm ultrafiltration terminal filters.

Standard spiral wound membranes rely on narrow feed spacers (typically 28 to 34 mil), making them highly susceptible to colloidal fouling and bio-plugging when treating high-solids or high-salinity wastewater (SDI > 3 or COD > 50 ppm). Disc Tube Reverse Osmosis (DTRO) features an open-channel hydraulic geometry with disc deflection plates and unobstructed flow, generating turbulent fluid dynamics that actively suppress concentration polarization and fouling. DTRO elements can operate reliably at feed pressures up to 90–120 bar and accept feed water with high SDI without clogging, making them the industry standard for landfill leachate, fracturing flowback, and brine concentration in Zero Liquid Discharge (ZLD) plants.

Our pharmaceutical purified water and Water for Injection (WFI) generation skids comply with cGMP, US FDA, and European Pharmacopoeia (EP) standards. Every system is supplied with a comprehensive Good Automated Manufacturing Practice (GAMP 5) validation dossier, including Design Qualification (DQ), Installation Qualification (IQ), Operational Qualification (OQ), and Factory Acceptance Testing (FAT) protocols. In addition, we supply complete 3.1 material traceability certificates, orbital weld logbooks with boroscope inspection video records, surface roughness (Ra) verification, and calibration certificates for temperature, pressure, flow, and conductivity sensors.

Standard skid-mounted reverse osmosis and EDI systems (capacities from 1 m³/h to 10 m³/h) are typically engineered, fabricated, automated, and factory-tested within 4 to 6 weeks from drawing sign-off. Large-scale custom containerized seawater desalination plants, DTRO packages, or multi-train ZLD crystallizer systems typically require 8 to 12 weeks. Systems are crated in seaworthy, vacuum-sealed barrier packaging with steel skid bases, ensuring safe sea-freight transport and rapid plug-and-play installation upon arrival at the customer site.

We provide comprehensive support through our Global Service structure. All our automated systems feature integrated industrial IoT modems or secure VPN gateways for remote engineering diagnostics, automated system tuning, and real-time operational troubleshooting. For on-site commissioning, our certified bilingual field service engineers deploy internationally to manage equipment positioning, interconnection checks, wet-commissioning, membrane loading, and client maintenance crew training.
