Hebei Huayu Environmental Engineering Co., Ltd has developed Ultrafiltration Pretreatment Equipment tailored for industrial manufacturing processes that demand reliable solids removal and microbial control before downstream treatments such as RO or EDI. This robust system enhances overall water-treatment efficiency and extends the service life of high-value membranes.
Process Description
Raw-Water Intake: A coarse screen and desander remove gravel, sand, and large debris.
Chemical Dosing: Optional coagulant or flocculant injection promotes aggregation of fine colloids, reducing membrane fouling.
UF Membrane Bank: Tubular or hollow-fiber modules arranged in multiple trains deliver capacities from 50 to 2,000 m³/h. Operating pressures range from 0.1 to 0.6 MPa.
Cleaning Protocols: The PLC triggers periodic backwash cycles based on trans-membrane pressure setpoints, and scheduled CIP routines ensure long-term permeability.
Control and Monitoring
An integrated control cabinet houses the PLC, variable-frequency drives, and human-machine interface. Sensors for pressure, flow, and turbidity feed real-time data to the control system, which adjusts operational parameters and logs performance for maintenance planning.
Construction Materials
All modules and piping in contact with feed water use corrosion-resistant materials—stainless steel for aggressive chemistries and reinforced polymers for general applications. Valves and fittings are selected for chemical compatibility, ensuring reliable operation under variable pH and temperature conditions.
Integration and Scalability
This pretreatment skid can be installed upstream of reverse-osmosis, electrodeionization, or other polishing systems. Modular design enables parallel operation of multiple units, allowing capacity expansion without interrupting manufacturing processes.
Manufacturing and Support
Hebei Huayu oversees the complete lifecycle: site assessment, system design, fabrication, and commissioning. Customer training covers routine operation, membrane cleaning, and troubleshooting. Service agreements include remote monitoring, periodic audits, and supply of spare membranes, ensuring uninterrupted pretreatment performance and downstream process protection.
