TREATMENT OF ACIDIC WASTEWATER FROM THIEN KE TIN ...

from the ,wastewater,, such as iron from 143.1 mg/L to 0.3 mg/L, ,copper, from 16.32 mg/L to 0.04 mg/L and manganese from 10.9 mg/L to 0.05 mg/L. The continuous mode with a hydraulic load of 100 l/h and an according retention time of three days showed constitutive contaminant removal. The effluent pH of the system was around 7 within six-day period.
