Wood grooves and DuPont membranes work very well!
Use the inexpensive machines from Beihua; for the membranes, those from Asahi Kasei or DuPont will work just fine

If *Enterprise uses Beihua Machinery and domestic membranes, give it a try. If it is a private enterprise, use the tanks from Beihua Machine and DuPont membranes. It’s just a suggestion.
It is recommended that you use Asahi Kasei’s electrolyzers and membranes. You can choose a 3K chlorine compressor, domestic hydrogen compressors, or York chlorine liquefaction units; feel free to contact me at hongjian2008vip@163.com. What is the name of your company? Where from?
Reply 1# sdlcssz: When I was working in a private company, I used equipment from Beihua Machinery and films from Asahi Kasei; when I was in a state-owned enterprise, I used fully imported films and equipment from Asahi Kasei!
Foreign companies have money, so they want products that are of good quality and reliable
Reply to 6# Hongjian: Well, I’m indeed planning to do that. It’s a quite reasonable combination, haha. But I don’t know much about equipment, so I hope you can give me some guidance. Could you explain the reasons for choosing them respectively?
I would also like to ask fellow sea water treatment experts: have there been any new methods for treating seawater that offer better investment returns, superior operational performance, and lower operating costs compared to pre-treatment followed by KAI membranes?
