Theoretical water output of reverse osmosis membranes from various brands

I really haven’t heard much about DuPont’s membranes, and I also rarely see companies using them. As for HydeNeng’s membranes, the market is currently full of mixed-quality products, and it’s difficult to determine exactly how many manufacturers there are. Some say that production also takes place in China; you might want to contact their Chinese representative office for inquiries. Pay close attention to details such as the actual water production capacity as well as the precautions to take when making a purchase, since the investment cost for these membranes is quite high. Make sure to get all the information clearly. DOW’s membranes are widely used in China nowadays, and their quality is generally recognized as good. I haven’t had much experience with Hydron’s membranes, so I can’t answer that well. I’m not very familiar with their quality, but their representative in China, Dr. Xu Ping, is highly respected in the industry; you might want to ask their Beijing office about it. Lastly, one more thing to mention is that Hydeon Corporation’s parent company is Nittodenshi of Japan. I wonder if LZ has some particular preference for Japanese products, haha...

:Handshake. Thank you, brother on the second floor; it’s better to choose Dow’s products. We must firmly resist Japanese goods.
