A schematic of the sludge chlorination process (Purifax process) is shown in Fig. 5. The sludge is first pumped through a macerator to reduce the particle size for optimum chlorine exposure. It is then mixed with conditioned sludge ahead of the recirculation pump at a ratio of 3.8 gal of recirculated sludge for each gallon of raw sludge. [Pg.419]

Figure 3 in introduces the Coxsackie Sewage Treatment Plant (STP). The plant s special wastewater chlorination facility, a combined chlorine contact chamber (CCC) second-phase final settler unit, is shown in Fig. 4. This section introduces the sludge chlorination facility of Coxsackie STP and its operational data. At Coxsackie STP, data generated during 19 batches of sludge chlorination are summarized in Tables 10-12. Characteristics of the underflow from the sludge dewatering beds for nine of those...

The slurry was treated at a rate of approx 2.5 L/s (40 gpm). The weighted average of the chlorine dosage was 830 mg/L or 10% of the dry weight of the sludge chlorinated. The chlorine dosage was adjusted to produce a pH of 2.3-2.8 in the chlorinated slurry. The pH of the unchlorinated slurry indicates that considerable nitrification had occurred on some batches before treatment. [Pg.429]
