Introduction
Industrial ultrafiltration (UF) is an effective membrane-based process for removing suspended solids, colloids, bacteria, and high-molecular-weight organics from a variety of feed sources. Hebei Huayu Environmental Engineering Co., Ltd offers Industrial UF Ultrafiltration System Plants designed to deliver reliable pretreatment or standalone clarification, helping industries maintain stable downstream operations and meet regulatory requirements.
System Architecture and Process Flow
Feed-Water Conditioning
Coarse Screening: Inline bar screens or basket strainers remove large debris, protecting UF modules.
pH Adjustment & Coagulant Dosing (when required): Ensures optimal floc formation to reduce fouling.
Ultrafiltration Train
Membrane Modules: Hollow-fiber or tubular membranes with pore sizes typically in the 0.01–0.1 µm range, arranged in skid-mounted racks.
Feed Pumps and Piping: Stainless-steel or FRP piping with variable-frequency drives (VFDs) to maintain constant cross-flow velocity and transmembrane pressure (TMP).
Backwash and Cleaning
Automatic Backwash: Periodic reversal of permeate flow through the membrane to dislodge accumulated solids.
Chemical Clean-In-Place (CIP): Scheduled alkaline and acidic cleaning sequences triggered by predetermined TMP rise or flux decline.
Permeate Handling
Polishing Filtration (optional): Fine cartridge filters to capture any residual particles.
Storage and Distribution: Pressurized permeate vessels with level control and recirculation pumps to supply downstream processes.
Key Technical Features
Hollow-Fiber vs. Tubular Options: Selection based on feed turbidity, solids loading, and site constraints. Hollow-fiber offers higher packing density; tubular is preferred for abrasive or fibrous feeds.
Modular Skid Design: Factory-assembled units reduce on-site installation time and allow future capacity expansion.
Automated Control Panel: PLC-based control with HMI for monitoring TMP, flux rate, conductivity, and backwash cycles.
Durable Materials: UF modules constructed from chemically resistant polymers; pressure vessels in stainless steel or GRP to withstand cyclic cleaning.
Operational Advantages
Stable Pretreatment for RO and NF
By removing particulates and colloids, UF protects more sensitive membranes downstream, extending their life and reducing chemical cleaning frequency.
Improved Water Reuse
Permeate suitable for boiler feed, cooling towers, and process water in factories, lowering freshwater consumption and effluent discharge.
Reduced Footprint
Compact skids fit within mechanical rooms or tight plant spaces, minimizing civil work requirements.
Predictable Maintenance
Automated backwash and CIP scheduling based on real-time performance data simplify operations and reduce manual intervention.
Applications
Cooling Tower Makeup Water: Prevents scaling and biological fouling in recirculating systems.
Process Water Clarification: In food and beverage, textile, and pulp & paper industries.
Municipal Water Pretreatment: As a polishing step ahead of downstream treatment or direct distribution in non-potable reuse projects.
Surface Water Intake: Removing algae and suspended growth from lakes and rivers.
Maintenance and Service Support
Hebei Huayu provides:
Routine Inspections: Verification of module integrity, TMP trends, and backwash efficacy.
Spare Parts Supply: Kits including membrane modules, seals, and gaskets for quick replacement.
Operator Training: Hands-on sessions covering daily checks, CIP procedure setup, and troubleshooting.
