![> Aluminum salt is used for chemical precipitation of phosphate from industrial wastewater. The
suspended solid (SS) concentration in wastewater is 0.25 g/l and the phosphorus concentration associated
with the SS is 0.007 g/l as P.
If the laboratory analysis of wastewater indicated that the alum dose of 1.5 moles Al/ 1 mole P would
provide sufficient phosphorus removal, estimate the quantity of the resulted dry sludge that is generated
and must be removed daily. The following data are available:
Alum formula: Al₂SO4.18H2O, Total phosphorus concentration= 0.017 g/l as P, wastewater flowrate =
4000 m³/d. [Al3+ PO4³
→ AIPO4]
Data you may need:
Mwt of: P = 31, Al-27, O=16, H = 1, S = 32, Fe = 56, C1= 35.5, Ca=40](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F499c0c07-fcbd-47c4-9e77-3f41fc78e0d8%2F1793b179-8ab2-4999-9500-143d91401f20%2Fe9weink_processed.jpeg&w=3840&q=75)
