Hebei Huayu Environmental Engineering Co., Ltd designs and supplies comprehensive industrial water treatment systems centered on reverse osmosis technology. These turnkey solutions integrate pretreatment, high-pressure membrane separation, concentrate handling, and post-treatment stages to produce water that meets stringent industrial requirements.
Pretreatment and Scale Management
Proper pretreatment is crucial for maintaining membrane performance and longevity. Raw water is first processed through sand and multimedia filters to remove suspended solids larger than 10 µm. Chemical dosing—using coagulants and pH adjusters—reduces colloidal matter before the water enters cartridge filters (5–20 µm) for fine-particle removal. Antiscalant injection prevents the precipitation of hardness salts, silica, and other scale-forming compounds on the membrane surface.
RO Train Configuration
The core of the system consists of multiple RO trains, each comprising high-pressure pumps and membrane vessels arranged in single- or two-stage configurations. Feed pressure, typically between 1.2 and 2.3 MPa, is optimized based on feed-water conductivity and desired recovery ratio. Operators can adjust the number of active membrane trains to match fluctuating water demands, ensuring continuous operation during maintenance or membrane replacement.
Concentrate Management and Energy Recovery
Concentrate (brine) streams from each train are collected and routed for disposal or further treatment. In high-recovery installations, isobaric energy-recovery devices reclaim pressure energy from the concentrate, reducing the overall energy footprint by up to 20 %. Concentrate disposal systems incorporate flow-equalization tanks and optionally downstream treatment (e.g., evaporation or crystallization) for zero-liquid discharge (ZLD) projects.
Automation and Remote Monitoring
A PLC/SCADA platform coordinates pump operation, monitors key parameters (pressure, flow, conductivity), and triggers CIP cycles when required. Real-time data is accessible via secure remote-access modules, allowing process engineers to review performance metrics and receive alert notifications from any location.
Construction Standards and Materials
Key structural components—pressure vessels, pipe manifolds, and supports—are built to ASME or ISO specifications. FRP vessels and carbon-steel skids are protected with corrosion-resistant coatings. All wetted metals in permeate circuits are stainless steel, and elastomers satisfy compatibility requirements for cleaning agents used during CIP. Electrical panels, cabling, and instruments conform to international safety directives.
Service and Lifecycle Support
Hebei Huayu provides a complete service package: feed-water analysis, process design, fabrication, erection, commissioning, and operator training. Post-installation, scheduled performance audits and membrane-health assessments inform maintenance planning, ensuring the RO system meets water-quality targets and cost-efficiency goals throughout its operational life.
