Investigating the Effective Parameters on the Performance of Industrial Wastewater Biological Treatment System in Pars Oil Refinery

Entrance of material and various elements to industrial wastewaters, with biological method is inevitable. Existence of some of them is the reason of bacteria death, but existence of some of them is not important for operation of purification. Bacteria population control are precious because of their essential role in the decomposition of organic matter which is very important and a high efficiency purification is free of any low and heavy materials and super heavy derivatives. This study in Pars Oil Refinery is trying to representation the effect of time of deflation for entrance fluids, purification at materials of wastewater and separation of heavy and low phases, and so will be diagnostic that entrance some of until, to materials to biological system with high volume how is effective in yield of biological pools and separation of them and life of bacteria to control of amount entrance pollution to pools, and the result of them will be pollution of environment and secular losses, to obvious company however about environment office sequel operation of that company will be with heavy consequences and sometime can be reason of shutdown production of companies.
