Hebei Huayu Environmental Engineering Co., Ltd specializes in industrial reverse osmosis systems engineered for high-capacity process-water production in sectors such as chemical manufacturing, power generation, and pharmaceuticals. These systems combine robust construction with precise control to deliver reliable performance under demanding conditions.
Key Components and Flow
Feed-water Conditioning: A multimedia filter train and automatic backwash softener remove turbidity and hardness ions, reducing scaling potential. Anti-scalant dosing further protects RO membranes from precipitation.
High-pressure Pumping: Variable-frequency drives (VFDs) adjust pump speed to maintain constant pressure (1.0–2.5 MPa), optimizing energy use and membrane lifespan.
Membrane Arrays: Skid-mounted pressure vessels hold multiple membrane elements arranged in single- or dual-stage configurations. The design balances recovery (up to 80%) with acceptable concentrate concentrations.
Concentrate Management: Brine discharge lines include throttling valves or automatic flush options. For zero-liquid discharge (ZLD) projects, additional evaporators or crystallizers may be integrated downstream.
Automation and Control
Advanced PLC systems monitor feed-water conductivity, permeate quality, differential pressure, and flow rates in real time. Operators access data and configuration via HMI panels or SCADA interfaces, enabling remote setpoint adjustments, alarm management, and historical trend analysis.
Construction and Materials
All wetted components are fabricated from stainless steel (SS304 or SS316L) or FRP, ensuring resistance to corrosion and chemical exposure. Piping and valves meet ANSI/ASME standards, and electrical installations conform to IEC and NEC regulations. Pressure vessels receive hydrostatic testing prior to delivery.
Applications
– Boiler Feedwater: Low-silica, low-TDS water to protect high-pressure steam systems
– Process Water: High-purity feed for chemical reactions and formulations
– Utility Systems: Demineralized water for cooling towers, condensers, and vacuum systems
After-sales and Maintenance
Hebei Huayu Environmental Engineering Co., Ltd provides commissioning services, performance validation, and operator training. Scheduled maintenance contracts include membrane cleaning, instrument calibration, and spare-parts provisioning to maintain optimal system availability.
