I’m seeking advice from experts: why is the filtering so slow?

Try adjusting the pH to above 4

The slow filtering is caused by the salts and saponifies produced by acid-base neutralization, which clog the filter cloth; this problem can be solved by finding ways to remove these substances, or by carrying out neutralization after filtering :)

The asphaltenes from acid and alkali washing can be easily handled using a centrifuge. Contact me!
