Reverse osmosis is to apply a pressure greater than the osmotic pressure to the solution to make water pass through a special semi-permeable membrane and separate it from the solution. Because this process is the opposite of osmosis, it is called reverse osmosis through. According to the different osmotic pressure of various materials, a reverse osmosis method greater than the osmotic pressure can be used for a certain solution to achieve the purpose of separating, extracting, purifying and concentrating the solution. It can remove organic matter with small ion range and low molecular weight in the filtrate, such as bacteria, poison, heat source, etc. The reverse osmosis device mainly separates the ion range in the solution. It does not require heating and has no phase change process, so it consumes less energy than traditional methods. The reverse osmosis device is small in size and easy to operate, and has a wide application range. The reverse osmosis device is used to treat industrial water without consuming a large amount of acid and alkali, without secondary pollution, and its operating cost is relatively low. The water treated by reverse osmosis method has high purity. It can not only remove impurities in the ionic range, but also remove organic pollutants, microorganisms, viruses and pyrogens, etc., which are difficult to remove by other methods.ost.
