HF Series hollow fiber pressure ultrafiltration membranes are designed for industrial and municipal water treatment where stable solid–liquid separation and compact system design are required.
They provide reliable removal of suspended solids, colloids, and microorganisms under pressure-driven operation, supporting long-term stable filtration performance.
HF Series – Hollow Fiber Pressure Ultrafiltration Membrane
The HF Series pressure ultrafiltration membrane utilizes a hollow fiber configuration operated under controlled transmembrane pressure.
It is engineered to deliver consistent filtration performance in applications requiring reliable pretreatment, clarification, or reuse water production.
Key Features
Water Sources
• Municipal tap water
• Seawater desalination pretreatment feedwater
• Industrial and municipal wastewater for reuse
Industries & Systems
• Drinking water purification systems
• Seawater desalination pretreatment
• Wastewater reuse and reclamation systems
Membrane Element Working Principle
Step 1 – Feed Water Inlet
Feed water enters the membrane module under controlled pressure.
Step 2 – Hollow Fiber Filtration
Water passes through the hollow fiber membrane walls while suspended solids and microorganisms are retained.
Step 3 – Permeate Collection
Filtered water is collected from the permeate side with stable flow.
Step 4 – Retentate Discharge
Concentrated solids are discharged or recirculated for further treatment.
Step 5 – Continuous Operation
The system operates continuously with periodic cleaning to maintain performance.
