Control of the pH value of the extraction water in the methanol recovery system
Thread Content
Treatment of the extracted water using cation and anion resins results in relatively stable pH levels, with iron ions levels being significantly reduced, averaging 1 mg/L
Is there a strong relationship between pH value and iron ions?
Which resin is the poster using, and how often does it need to be replaced?
Greater than 7; the standard set by manufacturers is 8
