RE: we have problem with alum sludge, p
You may consider these two issues:
1. Instead of discharing the sludge to the WWTP, use centrifudges/presses or similar to dry it and dump for landfills.
2. Dilute the alum sludge before discharging to the WWTP, so that the amount of alum sludge will not be too significant compare with the inflow of sewage. The amount of dilution will be mainly based on the process of the WWTP.
Hope these can help

What is it's detail chemical analysis? Alumina? Sodium? Potassium? etc.
