Скачать или смотреть Why Cold Water Means Less RO Output?

Phenomenon:Under standard conditions（25 °C）, as feedwater temperature decreases, RO membrane water production drops. Using 25 °C (77 °F) as the reference point, every 1 °C decrease in feedwater temperature typically results in a 2–3% reduction in permeate flow.

Cause:The viscosity of water is directly influenced by temperature. Higher temperatures reduce water viscosity, making it easier for water molecules to pass through the membrane. In contrast, at lower temperatures, water viscosity increases, creating more resistance to flow. This elevated resistance slows down the passage of water through the RO membrane, leading to lower permeate output.
