Industrial Wastewater Treatment sequence from Petrochemical companies of pars special Economic energy Zone

Waste water treatment of MOBIN PETROCHEMICAL Company has two separate processing trains. One train for COC Water together With Sanitary Wastewater, another for POC Water alone. Both trains have primary separation, comprising gravity separation followed by dissolved air flotation (DAF units). Because of the higher level of oil contamination in the COC Water, a secondary processing step is required for the COC train. Using biological treatment. The Sanitary water is fed directly to biological treatment rather than to primary separation, since it does not contain oil The most important stage in a waste water treatment plant is activated sludge stage(Aeration Basin), API, DAF, Clarifier, . Many factors affect the performance of waste water treatment. In this work, stage in a waste water treatment plant and effect of COD, MLVSS, pH and other parameter described
