What are the methods for cleaning membranes? Could those who use ceramic membranes share some information?
Is it Kugo’s ceramic membrane? Generally, it is washed with pure water after treating with acids or bases; there’s nothing special about it
Ceramic membranes, in layman’s terms, can be cleaned in any way you like, but it’s necessary to clean them frequently. Hehe
This supplier should have some operation guides! ! However, the advantage of ceramic membranes is their resistance to acids and alkalis, as well as their good oxidation resistance! !
Universal cleaning method for ceramic membranes: Alkaline cleaning: 1-4% sodium hydroxide, 0.2% sodium hypochlorite. 60-80 degrees, 30-40 minutes (purpose: to remove adsorbed substances such as proteins, pigments, and colloids). Acid washing: 2-6% nitric acid. 40-60 degrees, 20-30 minutes (Purpose: mainly to remove fouling from the membrane layer). If the above method cannot remove the contamination after being applied several times, it will be quite troublesome! Additionally: Ceramic membranes from certain manufacturers contain high levels of silicon, and their sintering temperature is insufficient; cleaning them using the above methods will shorten the membrane’s lifespan!
What types of fluids are your company’s ceramic membranes used to treat? Has a preliminary analysis been done on the main pollutants in the membrane? What type of pollution does the original poster think is responsible for it? What is the current impact on membrane flux?
