Product Details
High temperature industrial water treatment membrane RST8040-HS2 is a heat sanitizable reverse osmosis element designed for industrial systems that require high-temperature water disinfection and stable salt separation performance. The membrane is engineered for use in sanitary process environments where hot water sterilization is part of routine operation, particularly in food, beverage, dairy, and pharmaceutical water treatment applications.
The element adopts a full-fit sanitary spiral wound structure with high effective membrane area and uniform flow distribution, which helps maintain consistent permeate quality during repeated thermal cycles. It is suitable for systems requiring controlled hot water sanitation and continuous production of high-purity water under strict operating conditions.

Product Performance and Technical Specifications
The high temperature industrial water treatment membrane RST8040-HS2 features an effective membrane area of 35.2 m², providing sufficient active surface to support stable flux distribution and consistent permeate output under continuous industrial operating conditions. The full-fit sanitary element structure helps reduce inactive flow channels within the element and supports more uniform hydraulic performance.
With a 99.4% salt rejection rate, the membrane provides dissolved salt removal performance suitable for food processing, beverage production, and pharmaceutical water systems where permeate quality consistency is required. Under standard test conditions, the element delivers a permeate flow rate of 11,500 GPD (46.0 m³/day), supporting production capacity requirements in medium and large-scale industrial RO systems.
The RST8040-HS2 model combines membrane area, permeate productivity, and rejection performance for process applications involving thermal sanitization and controlled water quality requirements.
Long-Term Storage and Preservation Guidelines
For long shutdown periods, the high temperature industrial water treatment membrane should remain in a wet condition and be stored in an appropriate preservative solution to prevent microbial growth and help maintain membrane performance. Drying of a wetted element may affect flux stability and may cause irreversible membrane damage.
When the system is taken offline for an extended period, the membrane element is typically flushed with properly purified water before introducing a preservation solution compatible with reverse osmosis membranes. Storage conditions should minimize biological contamination, scaling potential, and exposure to incompatible chemicals. For sanitary process applications, preservation procedures should also be aligned with site cleaning and restart protocols.
Before returning the system to service, preserved elements are normally flushed thoroughly to remove storage solution residues, followed by gradual startup according to recommended operating procedures. Proper shutdown storage management can help maintain the operating condition of the membrane and reduce performance risks associated with idle periods.
FAQ
(1)Is this membrane suitable for pharmaceutical purified water systems?
Yes. The RST8040-HS2 is used in pharmaceutical water treatment applications, including purified water systems and sanitary RO processes where thermal disinfection is required.
(2)What permeate flow can I expect from this element?
The standard permeate flow is 11,500 GPD (46.0 m³/day) under published test conditions. Actual production may vary depending on feed water quality and system design.
(3)Is this membrane resistant to oxidizing chemicals such as chlorine?
No. Like standard polyamide RO membranes, it is sensitive to oxidants. Residual chlorine and other oxidizing agents must be removed before the feed reaches the membrane.
(4)What cleaning pH range is allowed?
The membrane operates within a continuous pH range of 2–10, with a cleaning pH range of 1–12 for CIP procedures, depending on cleaning chemistry and duration.
