Product Details
High temperature RO membrane elements in the RST-HS series are for sanitary separation processes requiring both stable desalination performance and repeated hot water disinfection. Notably, the RST4040-HS2 model features a fully filled, sanitary-grade spiral-wound configuration, boasting an effective membrane area of 8.3 square meters, a desalination rate of 99.4%, and a permeate flux of 2,500 GPD. This element effectively supports process water applications where the use of conventional membrane elements is precluded by stringent sanitary temperature requirements.
Manufactured on an automated membrane assembly line, this element features a structural design engineered to facilitate uniform flux distribution, minimize internal dead spaces, and ensure stable operational performance throughout thermal sanitization cycles. This product series is frequently specified for use in water systems within the food processing, beverage production, and pharmaceutical industries-particularly in environments with rigorous requirements regarding the thermal sanitization capabilities of RO membranes and their compatibility with associated processes, such as pasteurization.

Our RO Membrane Performance Advantages
(1)Stable Desalination Rate of Up to 99.4%
It is specifically engineered to maintain stable desalination performance under standard operating conditions, thereby meeting the stringent water quality requirements of sanitary applications.
Application scenarios involving ingredient water, process water reuse, or pharmaceutical water purification often require membrane elements to maintain consistent ion rejection performance throughout repeated sanitary disinfection cycles.
(2)Supports Hot Water Disinfection
A key distinction between traditional membrane elements and High Temperature RO Membrane elements lies in the latter's ability to support thermal disinfection processes.
The RST HS series membrane elements are capable of withstanding controlled hot water disinfection procedures, tolerating temperatures of up to 80°C during thermal stabilization and disinfection protocols.
This feature is particularly well-suited for systems where operators prefer utilizing hot water disinfection rather than frequent chemical disinfection.
(3)Sanitary Full-Fit Design
This membrane element features a sanitary full-fit design, effectively minimizing bypass gaps and stagnant zones that could otherwise lead to microbial accumulation.
In food and pharmaceutical systems, minimizing "dead zones" is often a critical design consideration during the engineering of sanitary processes.

FAQ
Q: Can this membrane operate continuously at 80°C?
A: No. Maximum continuous operating temperature is 55°C. 80°C applies to controlled thermal stabilization and sanitation procedures, not normal continuous operation.
Q: What pretreatment is required?
A: Feed water should be free of residual chlorine, oxidants and scale-forming compounds. Standard pretreatment depends on feedwater analysis and system design.
Q: Is hot water sanitization a substitute for chemical cleaning?
A: Thermal sanitization can support microbial control, but cleaning requirements depend on fouling type and process conditions.
Q: Is this high temperature RO membrane compatible with standard 4040 pressure vessels and systems?
A: Yes. The RST4040-HS2 is manufactured in standard 4-inch 4040 dimensions and is designed for compatibility with conventional 4040 pressure vessels and most industrial RO skid configurations. For retrofit projects involving hot water sanitization, verification of vessel, seal material, and system temperature tolerance is recommended.
