Instructions
The flow rate of a single membrane element may vary, but the range of variation will not exceed ± 15%;
2. The stable desalination rate generally needs to be tested after 24-48 hours of continuous operation, depending on the inlet water quality and operating conditions.
3. Stability treatment must be carried out before the components are put into operation, during which a one-time decrease in flux may occur. The standardized values in the table above are the performance parameters that have been stabilized.
High temperature resistant material：
Using polyamide composite materials or special modified materials (such as aromatic polyamide), it can withstand high temperature environments of 60 ℃ -85 ℃ (conventional reverse osmosis membranes usually have a temperature resistance of ≤ 45 ℃), and can withstand thermal disinfection methods such as steam and hot water without damaging the membrane structure.
Enhance mechanical performance：
The membrane support layer and protective layer have been optimized to enhance their resistance to thermal expansion and contraction, avoiding deformation, rupture, or damage to the desalination layer of the membrane element at high temperatures.
Efficient thermal disinfection compatibility：
It can be effectively killed by hot water circulation (such as continuous flushing with 80 ℃ hot water for 30-60 minutes) or steam sterilization, without the need for frequent use of chemical agents (such as sodium hypochlorite), reducing the risk of chemical residues and membrane fouling.
Long term antibacterial ability：
Thermal disinfection can penetrate deep layers of biological membranes, destroy microbial cell structures, and extend the cleaning cycle and service life of membrane components.
Adaptability to high temperature environment：
Suitable for scenarios with high raw water temperatures (such as industrial wastewater, geothermal water sources), or water treatment systems that require operation at high temperatures (such as process water in the food and pharmaceutical industries), without the need for additional cooling treatment, reducing energy consumption.
Simplify the disinfection process：
The hot disinfection operation can be automated and standardized, reducing manual intervention, especially suitable for scenarios sensitive to chemical agents (such as drinking water and pharmaceutical water), to avoid the impact of chemical agents on subsequent processes.
High desalination rate stability：
Under high temperature conditions, it can still maintain excellent desalination rate (usually ≥ 99.5%), and its ability to intercept impurities such as inorganic salts, organic matter, and microorganisms is not affected by temperature, ensuring that the quality of the produced water meets the standard.
Flexibility of flux regulation：
When the temperature increases, the viscosity of water decreases, and the membrane flux may slightly increase (to be controlled within the design range). The water production can be optimized by adjusting the temperature, while avoiding excessive high temperature that may cause membrane performance degradation.
Special industry needs：
Widely used in food and beverage (such as beer and dairy production), pharmaceutical and hygiene (preparation of injection water), electronics industry (high-purity water) and other fields with strict microbial control, meeting the requirements of GMP (Good Manufacturing Practice) and other standards.
Anti pollution and long lifespan：
Thermal disinfection can effectively suppress biological contamination on the membrane surface, reduce the frequency of chemical cleaning, lower the risk of mechanical damage and chemical degradation of membrane components, and extend the replacement cycle
Strict temperature control：
Strictly follow the temperature upper limit requirements of the membrane manufacturer (such as 80 ℃± 5 ℃) to avoid irreversible damage to the membrane caused by overheating; The heating and cooling rate should be slow (usually ≤ 5 ℃/min) to prevent thermal stress damage.
Requirements for supporting systems：
High temperature resistant membrane shells, pipelines, and connectors are required, and thermal expansion compensation should be considered in system design to avoid mechanical failures.
