Figure 2-6. Schematics of typical ferric chloride and lime and polymer condition-
ing systems (WPCF 1983 and WEF 1992).
b. A summary of using polymers for various sludge applications is presented
in Tables 2-4 and 2-5. Because of the numerous types of polymers that are
commercially available, specific polymer dosages are not shown; however, as a general
rule the application is less than 0.5 g/kg (10 lb/ton).
