Heat Sanitizable RO Membrane HSF Series
Hot water sterilization RO membrane engineered for pharmaceutical water systems, food & beverage processing, and high-purity industrial applications.
Product Overview
The HSF Heat Sanitizable Reverse Osmosis Membrane is specifically designed for industries requiring strict hygiene control. Unlike conventional RO membranes, HSF membranes can withstand high-temperature hot water disinfection up to 85°C, enabling chemical-free sterilization and significantly reducing operational risks.
Its sanitary open-channel design eliminates dead zones inside the pressure vessel, preventing microbial growth and ensuring consistent water quality output.
Designed for:
- Food & Beverage Processing
- Pharmaceutical Water Systems
- Purified Water & High-Purity Applications
Key Features & Advantages
Hot Water Sanitization up to 85°C
Thermal sterilization without chemicals. Ideal for GMP and FDA-related industries. Reduces CIP chemical usage and cost.
Sanitary Open-Channel Design
Eliminates stagnant water zones and prevents bacterial accumulation. Improves overall system hygiene level.
High Salt Rejection Performance
Stable rejection of 99.5%, minimum 99.0%. Suitable for high-purity water production requirements.
High Reliability in Critical Use
Designed for frequent sterilization cycles. Maintains performance stability under thermal stress over long-term operation.
Reduced Operating Cost
Less chemical cleaning, lower downtime for sterilization, and extended membrane lifecycle in hygienic systems.
Typical Applications
- Pharmaceutical PW / WFI pretreatment
- Dairy & beverage production lines
- Biotech process water systems
- Food ingredient concentration
- CIP-compatible RO systems

Installation & Operation Notes
Increase feed pressure gradually within 30-60 seconds to avoid membrane damage.
Avoid any back pressure on the permeate side at all times.
First hour of permeate output should be discarded during initial startup.
Wet membranes must be kept moist at all times -- never allow to dry out.
For long-term shutdown: preserve with 1.5% sodium bisulfite solution.
