Please ask an expert to explain forward osmosis

With a glass of water separated in the middle by a membrane, and water of different concentrations placed on each side, you will observe that the water with the lower concentration moves toward the side with the higher concentration – this is osmosis. Extending this idea, drinking diluted pesticides:lol:lol will lead to death faster than drinking pure pesticides:lol

At the NAMS annual meeting of the North American Membrane Society held in Rhode Island in June 2004, I told the inventor of this osmotic process that it could be used for concentrating special fluids such as heat-sensitive fluids, but not for desalinating seawater or treating wastewater. For example, when using ammonium carbonate as the extraction liquid, it takes approximately 0.35 tons of steam to evaporate the ammonia from one cubic meter of water; this results in a water production ratio of 3 for the entire process, which is equivalent to the energy-saving efficiency of a four-effect evaporator. In contrast, the water production ratio for seawater desalination using multi-effect evaporation methods is currently 14. He can’t deceive people in the United States, so he comes to China and teams up with some academic scammers to trick technical investors, *** employees, and other academic fools. In our Tianjin dialect, this process is described as moving the child from the pee spot to the poop spot; or, in the words of our secretary, it’s called taking off the kuzi and putting on the pi. Can you find any papers by using osmosis and TJDX as keywords? A few years ago, over 20 professors from TJDX College of Chemical Engineering who worked in the fields of membrane separation, distillation, and polymer materials met together and rejected this idea; anyone who studied it was considered an idiot.

A U-tube, with a high-concentration solution on one side and a low-concentration solution on the other; there is a semipermeable membrane in between, and the process by which the liquid from the low-concentration side moves toward the high-concentration side through this membrane

You can look it up on Baidu for specific details； So far, no large-scale, mature applications have been reported. Mainly, both the investment and operating costs are very high.

The greatest advantage of forward osmosis is energy savings, and it has great potential for development. Osmotic reverse osmosis: A new hotspot in energy-saving and emission-reduction technologies for the petrochemical industry. The title above is from an article published by HaiChuan Fa; you can search for that title to read the article.

In simple terms, it is a filtration method that uses saltwater with a higher concentration to transport water from the solution on the other side of the membrane through a concentration gradient. It is used in environments with special requirements and is not recommended for simple concentration processes.
