Reverse osmosis (RO) is a water purification process that uses a semi-permeable membrane to separate water molecules from other substances. RO applies pressure to overcome osmotic pressure that favors even distributions.
逆滲透 （英語： Reverse osmosis，簡稱RO）、 反滲透，是一種 淨化水 的辦法。. 原理是利用滲透作用，將清水（低張溶液）和鹹水（高張溶液）置於一管中，中間以一支允許水通過的 半透膜 分隔開來，可見到水從 滲透壓 低（低張溶液）的地方流向滲透壓高（高張 ...

2024年9月4日 · Reverse osmosis is a separation technique in which pressure applied to a solution forces the solvent through a semipermeable membrane from a region of low concentration to one of high concentration, leaving behind the solutes. Reverse osmosis is often used for water purification.
2022年2月15日 · Reverse osmosis or RO is a water purification process that presses water through a semi-permeable membrane. Particles, molecules, and ions that are larger than water molecules remain on one side of the barrier, while nearly pure water exits across the membrane.
2019年7月3日 · Reverse osmosis or RO is a filtration method that is used to remove ions and molecules from a solution by applying pressure to the solution on one side of a semipermeable or selective membrane. Large molecules (solute) can't cross the membrane, so they remain on one side. Water (solvent) can cross the membrane.
2023年5月12日 · Reverse osmosis is one of the processes that makes desalination (or removing salt from seawater) possible. Beyond that, reverse osmosis is used for recycling, wastewater treatment, and can even produce energy. Water issues have become an extremely
什麼是逆滲透膜 (Reverse Osmosis, RO)? RO膜（名目分子量100～300 dalton）是一種可將水中污染物質去除 90～99 % 的方法，包括其它純化方法無法去除的有機物質、次微米粒子、微生物與無機鹽類。 利用此一性質，RO膜已廣泛應用在海水的淡化技術上。 滲透 (Osmosis) 是指，當半通透膜兩側的滲透壓不同時，低滲透壓側的水分子就會穿透至高滲透壓側。 就如同稀薄溶液與高濃度溶液（如純水與海水）相接觸時，水自然會通過半通透膜從稀薄溶液流向高濃度溶液，其移動會持續到滲透壓與液面差壓力達到平衡為止。 相反的，如果加上比滲透壓差更大的壓力，就可以使水由高濃度溶液流向稀薄溶液，而這個現象就稱為逆滲透 (Reverse Osmosis)。 (見下圖)
Reverse osmosis (RO) is a liquid-driven membrane process, with the reverse osmosis membranes being capable of allowing water to pass through while rejecting solutes, such as salts or low molecular weight organic materials.
Compared to traditional filtration technologies that rely on a screen or filter to remove particles, reverse osmosis (RO) is a pressure-driven separation process that employs a semipermeable membrane and the principles of crossflow filtration. Reverse osmosis water treatment provides the finest level of filtration.
