Hebei Huayu Environmental Engineering Co., Ltd specializes in the engineering, fabrication, and commissioning of large-scale industrial reverse osmosis (RO) water treatment plants. These installations produce high-quality permeate for critical applications such as boiler feed, ultrapure water generation, and process water supply in heavy industry.
End-to-End Process Design
A typical industrial RO plant integrates multiple process stages:
Feed-water Screening and Aeration: Removal of floating debris and degassing of volatile compounds.
Chemical Dosing: Coagulants, flocculants, and pH adjusters optimize feed-water clarity and minimize scaling risk.
Multimedia and Carbon Filtration: Sequential filters lower turbidity to below 1 NTU and remove organics and chlorine.
Desalting via RO: High-pressure pumps deliver water to membrane trains operating at 1.5–2.5 MPa. Single- or two-stage configurations achieve permeate recovery of 70–85 %.
Permeate Polishing: Degassers, UV disinfection, or electrodeionization (EDI) units refine water to meet end-use specifications.
Concentrate Handling: Zero-liquid-discharge (ZLD) options—including forced-circulation evaporators or crystallizers—recover additional water and recover salts for reuse or safe disposal.
Control Strategy
A centralized DCS or SCADA system oversees all unit operations, from chemical dosing rates to membrane-train pressures. Automated cleaning cycles schedule CIP and backwash sequences based on trans-membrane pressure (TMP) rise or flux decline. Historical data logs enable performance benchmarking and predictive maintenance, reducing unplanned downtime.
Mechanical Design and Materials
Structural steel skids support pumps, vessels, and ancillary equipment, while FRP or epoxy-lined steel vessels handle high pressures and corrosive feed waters. Stainless-steel piping networks distribute feed, permeate, and concentrate streams. All electrical and instrumentation hardware is housed in climate-controlled enclosures rated to IP54 or higher.
Environmental and Economic Impacts
By incorporating energy-recovery devices, optimizing chemical dosing, and deploying advanced pretreatment, these plants minimize specific energy consumption and chemical costs. ZLD configurations eliminate liquid effluent, reducing environmental compliance burdens. Lifecycle cost analyses guide capital-expenditure decisions and highlight opportunities for operational savings.
Commissioning and After-Sales Support
Hebei Huayu provides thorough FAT/SAT procedures, performance guarantee testing, and operator certification programs. Long-term service agreements include membrane-health monitoring, reagent supply, and rapid-response maintenance teams to maintain plant performance and water-quality targets over decades of operation.
