Hebei Huayu Environmental Engineering Co., Ltd offers industrial reverse‑osmosis (RO) treatment plants designed to produce high‑quality permeate for applications such as boiler feed, ultrapure‑water generation, and process‑water supply. Reverse osmosis employs semi‑permeable membranes to separate dissolved salts, organics, and other low‑molecular‑weight contaminants, achieving typical salt‑rejection rates above 96% under suitable operating conditions.
Key Components and Process Steps
Feed‑water Pre‑conditioning: To protect RO membranes, feed water undergoes multimedia filtration, anti‑scalant dosing, and activated‑carbon polishing. These steps reduce particulates, organohalides, and scaling precursors (e.g., hardness ions).
High‑pressure Pump: A variable‑speed, energy‑efficient pump supplies feed at pressures between 1.0 and 2.5 MPa, regulated to maintain target recovery and permeate quality.
Membrane Arrays: Elements arranged in pressure vessels operate in single- or multi‑stage configurations. The system design balances recovery ratio (typically 60–80%) against permissible concentration factors to avoid scaling or fouling.
Permeate and Concentrate Management: Permeate is collected, post‑treated with degassers or UV, and delivered to storage. Concentrate (brine) is either discharged under compliance limits or further treated for zero‑liquid discharge.
Performance Optimization
RO plants incorporate differential‑pressure sensors, conductivity meters, and flow meters for each membrane train. Automated backwash or chemical‑enhanced backwash sequences extend membrane life by removing particulate fouling. Anti‑scalant dosing is adjusted in real time based on feed-water chemistry and recovery trends.
Design Flexibility
Units are skid‑mounted for rapid installation, or fully containerized for plug‑and‑play deployment. Capacities range from 5 m³/h for pilot systems to over 2,000 m³/h for large industrial complexes. Modular expansion allows addition of membrane trains without shutdown, accommodating incremental production growth.
Material Selection and Standards
Pressure vessels are fabricated from FRP or carbon‑steel with anti‑corrosion lining. Membrane housing housings and piping use stainless‑steel or Viton/EPDM elastomers, chosen for compatibility with cleaning chemicals. All electrical installations are carried out to IEC/CE standards, and instrumentation is sourced from reliable suppliers to ensure stable long‑term operation.
Service and Maintenance
Hebei Huayu Environmental Engineering Co., Ltd provides on‑site commissioning, performance guarantee testing, and operator training. Spare membrane sets, high‑pressure seals, and chemical kits are supplied for routine maintenance. Remote monitoring options diagnose issues early and reduce downtime.
