Question

1-1. The raw water supply for a community contains
18 mg/L total particulate matter. It is to be treated by
addition of 60 mg alum (Al2(SO4)3-14H;O) per liter of
water treated. Essentially, all the added alum precipi-
tates represented by the following reaction:
Al2(SO4)3 · 14H20 → 2 Al(OH);(s) + 3So,-
+ 6H* + 8H2O
For a total flow of 7500 m/d, compute the daily alum
requirement, the total concentration of suspended sol-
ids in the water following alum addition, and the daily
load of particulate solids requiring disposal (including
both those initially present and those formed during
treatment).
