There is a large amount of dark red substance in the inlet and outlet hoses of the electrolyzer cathode

There is a large amount of dark red substance in the inlet and outlet hoses of the electrolyzer cathode; could it be ferric chloride? But once it exits the resin tower, isn’t the iron ion content quite low? So what exactly is this red substance?
“There is a large amount of dark red substance in the inlet and outlet hoses of the electrolyzer cathode; could it be ferric chloride? But once it exits the resin tower, isn’t the iron ion content quite low? So what exactly is this red substance? ”——Both the inlet and outlet of the catholyte are alkaline solutions; it is the anolyte that is saltwater and flows through the resin tower. So, are you referring to the cathode or the anode?
What type of pipes is the OP using in their brine system? Lined pipes or titanium pipes?
The topic was entered incorrectly; it’s the catholyte, which is an alkaline solution, not saltwater
May I ask if this is the case during normal production, or during the shutdown cycle, or when draining liquid during shutdown?
What is the material of the pipeline leading to the electrolytic cell? It’s really strange.
A dark red color appears on the cathode side; it is necessary to analyze what components are present in the alkaline solution. In a situation like this, it’s very likely that there is a problem with the cathode coating. Detects the iron content in alkaline solutions and soft water. When parking, check whether there are pinholes in the ion membrane.
How long has this situation been going on since it first appeared?
It’s been quite some time; I asked the team leader if it doesn’t affect production. Is that really the case?
