The ,wastewater, (pH ~7.8, electric conductivity ~3.6 mS/cm) contained a mix of metals/metalloids (Ar 12 µg/L, Sb 19 µg/L) and sulfate (~2 g/L). The ,study, measured fluctuations in the removal efficiency of target compounds due to freezing and ,thawing, conditions. Removal of sulfate and Ar decreased during frost periods, while removal of Sb ...

The experiment was designed as follows. -chlorophenol was added to fresh p sludge (P0) in the following amounts: 100, 200, 300, 400, and 500 mg Cl/kg (dry weight basis), thus the samples were denoted by P1, P2, P3, P4, and P5, respectively. The sludge samples, P1–P5, 3 g each, were immersed in 25 cm 3 of distilled water and shaken for 1 hour.
