Does anyone have an equation and/or rule-of-thumb used to estimate alum sludge production in a potable water plant? Basically we're continuously removing alum sludge from settling basins and dicharging to a pair of gravity thickeners. We pump from the bottom of the thickeners to a 1 meter belt filter press. I'm guessing 1% solids from the basins, 2% from the thickeners, and maybe 15% from the belt press. Also, what does everyone use for thickener loading rates? I've seen rates from 100 to 200 gpd/sf. thanks

Alum sludge production equation
- Thread starter wpr
- Start date
Alum sludge volume can be calculated using the total chemicals used plus a factor for turbidity.
We just built an industrial water treatment plant (using alum) that has a design solids loading rate of 5 lbs/ft2/day for the sludge thickener.
