Effluent Treatment Plant - ETP

EFFLUENT TREATMENT PLANT (ETP) - ETP process are summing up of some steps: a) Primary treatment (Physical and chemical): Oil, fatty acids and suspended solids could be removed by Screening, Coagulation, Flocculation, Fluidization, Electrolysis, Settling and Precipitation etc. b) Biological treatment: is used to lower organic load of soluted organic compounds. There are two main categories: Aerobic treatment, Anaerobic treatment. In aerobic systems the water is aerated with compressed air (in some cases oxygen). Anaerobic systems run under oxygen free conditions.
