Introduction
Hebei Huayu Environmental Engineering Co., Ltd provides industrial reverse osmosis (RO) water filters designed to remove dissolved salts, suspended solids, organic compounds, and microorganisms from feed water streams. These filters employ semi-permeable membranes under controlled pressure to produce permeate of consistent quality, suitable for boiler feed, cooling-tower make-up, process water, and other industrial applications.
Core Components and Process
Each industrial RO filter consists of a feed-water pretreatment stage, high-pressure pump, RO membrane vessels, and post-treatment modules. In the pretreatment stage, multimedia filters and activated-carbon beds reduce turbidity, organics, and chlorine, protecting membranes from fouling or oxidative damage. The high-pressure pump supplies water at pressures between 1.0 and 2.5 MPa, forcing it through RO elements arranged in single- or multi-stage arrays. Clean permeate is collected, while concentrate (reject stream) is discharged or further treated for recovery or disposal.
Design Features
– Modular Configuration: Skid-mounted units can be scaled by adding membrane trains, allowing capacity increases without interruption.
– Automated Controls: Integrated PLC/SCADA systems adjust pump speed, monitor differential pressure, and regulate anti-scalant dosing according to feed-water chemistry and recovery targets.
– Energy Recovery Options: For high-recovery plants, isobaric energy-recovery devices reduce overall power consumption by reclaiming pressure from the concentrate stream.
Materials and Construction
Key pressure vessels are fabricated from fiberglass-reinforced plastic (FRP) or carbon-steel with anti-corrosion lining. Piping and fittings in permeate lines use 304L or 316L stainless steel to preserve water purity. Elastomeric seals are selected for compatibility with cleaning chemicals and feed-water pH. All welds undergo non-destructive testing, and electrical systems meet IEC and CE requirements.
Applications and Benefits
Industrial RO filters from Hebei Huayu are employed in petrochemical plants, food and beverage processing, pharmaceutical production, and power generation. By achieving salt-rejection rates above 96%, they extend equipment life, improve process efficiency, and reduce scaling in boilers and heat exchangers. High-flux membranes and precise control systems minimize chemical usage and downtime for cleaning cycles.
Maintenance and Support
Routine maintenance includes membrane integrity testing, periodic CIP (cleaning-in-place) with mild acid or alkali solutions, and replacement of prefilter cartridges. Hebei Huayu provides commissioning services, operator training, and remote monitoring options to ensure continuous performance and rapid troubleshooting. Spare parts kits and maintenance schedules are supplied to streamline long-term operation.
