Nanofiltration and reverse osmosis technologies demonstrate remarkable advantages in
the water treatment
field by virtue of their precise separation performance and flexible adaptability. Among
these technologies, ultra-
low pressure nanofiltration/reverse osmosis membranes can drastically reduce operating
energy consumption
while efficiently retaining pollutants such as organic matter and divalent ions in water. They
are suitable for low-
pressure scenarios including advanced purification of municipal tap water and reuse of
industrial wastewater,
balancing treatment efficiency with cost control. On the other hand, reverse osmosis
membranes dedicated to
seawater desalination feature excellent contamination resistance and high desalination
rates, enabling stable
operation under harsh conditions of high salinity and high osmotic pressure. As a core
technology addressing
freshwater scarcity in coastal areas and islands, these membranes can directly convert
seawater into freshwater
that meets drinking or industrial standards, facilitating the recycling and efficient
development of water
resources.
