Koether et al. (1993, 1997). Partially neutralized ,aluminum, sulfate is a solution formed by adding powdered CaCO 3 to concentrated alum, increasing the cost by only 10% above that of liquid alum (Beecroft et al., 1995; Koether et al., 1997). It is similar to PAC in that it contains several preformed Al polymers and is less ,acidic, than alum.
