The water we drink daily contains a large amount of salts and various elements, many of which are necessary for our human body. But seawater is different. The concentration of various substances in seawater is too high,
far exceeding the hygiene standards for drinking water. If consumed in large quantities, it can lead to excessive entry of certain elements into the human body, affecting human health and even causing poisoning. Therefore,
seawater needs to be desalinated before it can be consumed. So how can seawater be desalinated into drinking water? Now let me introduce to you:
Seawater desalination is the process of removing salt from seawater and turning it into fresh water. There are dozens of methods for seawater desalination, including distillation, electroosmosis, freezing, membrane separation, and so on.
At present, the application of reverse osmosis membranes in seawater desalination has become the most widely used method due to its advantages of simple equipment, easy maintenance, and modular equipment. Reverse osmosis seawater
desalination technology is mature and advanced, with a desalination rate of up to 99.5%. Reverse osmosis membrane is an artificial semi permeable membrane with certain characteristics made by simulating biological semi permeable
membranes, and is the core component of reverse osmosis technology. The principle of reverse osmosis technology is to separate other substances from water under the action of osmotic pressure higher than the solution, based on the
inability of other substances to penetrate the semi permeable membrane. The pore size of reverse osmosis membranes is very small, so they can effectively remove dissolved salts, colloids, microorganisms, organic matter, etc. from water.
Through this method, the seawater desalination equipment has the advantages of good water quality, low energy consumption, no pollution, simple process, and relatively simple operation.
