Note: The gross net weight of the membrane element is calculated based on the average value of the dry membrane weight. The error between the actual weight and the average value is ±5%.


■ Frequently Asked Questions
1. How many years can a membrane element generally be used?
The service life of the membrane depends on the chemical stability of the membrane, the physical stability of the element, cleanability, water source, pretreatment, cleaning frequency, operation and management level, etc. Generally, it can be used for 3 years under correct and reasonable operation.
2. How to store the membrane element?
A: The suitable temperature range is 0-45℃; it is recommended to store it at about 25℃ close to room temperature.
B: If conditions permit, it must be avoided from being exposed to temperatures below freezing. If the membrane element accidentally freezes, it must be slowly melted before use, and it will no longer meet the warranty terms after this happens.
C: Even if the membrane element is in the original packaging box, it is not allowed to be exposed to the sun; it is recommended to store it indoors and avoid long-term sunlight exposure.
3. What is the effect of pressure and temperature on water production?
The higher the pressure and temperature, the higher the water production, and vice versa. When operating under higher temperature conditions, the operating pressure should be lowered to keep the water production unchanged, and vice versa. Pay attention to the ability of the membrane component to withstand high pressure and high temperature.
