Hebei Huayu Environmental Engineering Co., Ltd offers industrial reverse osmosis (RO) water filters designed to remove dissolved salts, suspended solids, organic compounds, and microorganisms from a variety of feed-water sources. Utilizing semi-permeable membranes under precisely controlled pressure, these filters deliver permeate with consistently low total dissolved solids (TDS), making them suitable for applications including boiler feed, cooling-tower makeup, and process water production.
System Configuration and Pretreatment
Each industrial RO water filter begins with a pretreatment stage to protect the membranes and ensure steady operation. Feed water first passes through multimedia filters to remove turbidity and particulates larger than 20 µm. Activated-carbon beds then adsorb residual chlorine, organics, and trace chemicals that could degrade membrane integrity. In systems handling hard water, antiscalant dosing is applied to inhibit scale formation on membrane surfaces.
Membrane Module and Pressure Regulation
Following pretreatment, the water is pressurized by a variable-speed high-pressure pump to 1.0–2.5 MPa, depending on feed-water salinity and desired recovery rates. Water enters membrane vessels containing spiral-wound RO elements with a typical salt-rejection rate above 95%. Differential-pressure gauges monitor fouling tendencies, while flow meters on permeate and concentrate lines allow operators to fine-tune recovery ratios (commonly 60–75%) to balance water yield against concentrate management.
Control and Monitoring
An integrated PLC-based control panel continuously tracks feed-water temperature, pressure, conductivity, and flow. Alarms notify operators of deviations beyond preset thresholds, and automated backwash or chemical-enhanced clean-in-place (CIP) routines restore membrane flux when performance falls below target levels. Data logging supports trend analysis, helping maintenance teams schedule interventions before significant losses in efficiency occur.
Materials and Construction
Pressure vessels are fabricated from fiberglass-reinforced plastic (FRP) or epoxy-lined carbon steel to withstand operating pressures and corrosive environments. Permeate piping uses stainless steel (304L or 316L) to preserve water purity, while elastomeric seals and gaskets are selected for compatibility with pH ranges encountered during cleaning. All welds undergo non-destructive testing, and electrical components comply with IEC and CE standards.
Applications and Benefits
– Petrochemical Industry: Reliable removal of dissolved salts protects heat-exchange surfaces and extends boiler life.
– Food & Beverage: Consistent permeate quality safeguards product taste and quality.
– Power Generation: Low-TDS water reduces scaling in condensers and steam turbines.
– Manufacturing: Process water with controlled mineral content improves product consistency and reduces waste.
Hebei Huayu Environmental Engineering Co., Ltd provides on-site commissioning, operator training, and preventive-maintenance plans—including spare parts kits and remote diagnostics—to ensure each RO filter operates efficiently throughout its service life.
