Water Treatment. The source of water for this experiment was a pilot plant located on the Seine River upstream from Paris, France (Figure 1). The pilot plant uses an upflow solids contact clarifier (Pulsator, Degremont, Rueil Malmaison, France) followed by rapid sand filtration (RSF). The filtered water is then distributed over four treatment lines to evaluate the efficiency of various ozone-GAC combinations (ozonation rates of 1 or 5 ppm O3 and 10-30 min of contact time). The GAC used in this study was Calgon F-400 (Calgon Corp.). Disinfection by chlorine or chlorine dioxide completed the process. In this chapter, line 3 treatment was not considered a complete treatment for the water supply. This line was studied to evaluate the efficiency of a high ozonation rate.

Turbidimetric Titrations. Poly(dimethyldiallylammonium chloride) (PDMDAAC), a commercial sample "Merquat 100" from Calgon Corp. (Pittsburgh, PA) with nominal molecular weight 2 x 10 and reported polydispersity of Mw/Mn = 10, was dialyzed and freeze-dried before use. All proteins were obtained from Sigma Chemical Corp. Solutions were... 

Dobbs and Cohen (mentioned earlier) reported that Filtrasorb-300 (Calgon Corp.) adsorbs 80 mg/g at this concentration. Thus, An /AC = 80 (mg/g)/0.0003 (mg/cm ). pg = 31.2 Ib/fP (or 0.5 g/cm ), e = 0.70. They also noted that a line powder (200 x 400 mesh, or 0.05-mm diameter) required about 5 hr to equilibrate. Equation (14.12) suggests the time required to equilibrate a 0.5-mm diameter granule. Namely, the parameter would be constant, as would the effective diffu-...
