The high-temperature resistant membrane is a high-performance separation product specifically developed for challenging conditions, including high temperature, high salinity, and highly corrosive environments. Through optimized design of the flow distributor, membrane sheets, membrane housing, and sealing components, it achieves long-term stable operation in saltwater at 80 °C.
This membrane offers excellent corrosion resistance and anti-fouling performance. Structural innovations reduce energy consumption and heat loss, providing an efficient and reliable solution for high-temperature wastewater treatment and resource recovery.
The high-temperature membrane operates on a pressure-driven separation mechanism. Under elevated temperatures, it selectively separates solutes from solvents for concentration and purification.
The system uses an isobaric structure to prevent flow maldistribution, while the swirl CD flow distributor optimizes fluid distribution, reduces resistance, and enhances mass transfer efficiency. The central tube is made of chlorine-resistant material, supported by an outer tie-rod structure, ensuring stable operation and high separation performance under high-temperature, high-pressure conditions.
