The Efficiency of Flocculants in Biological Treatment
with Activated Sludge

Abstract:

Studies were made on the water from the oil sludge basin where petroleum residues were stored as well as sludge from the treatment plant of wastewater from refinery. The aim of the experiment program is biodegradation of petroleum waste deposit and removal of contaminants, turning it in a state that allows chemical, physical and biological treatment. Contaminants of these samples are damaging the environment and there is important to find solutions in order to eliminate these contaminants. Five samples were collected from different sampling points. Samples were homogenized, then mixed and an average sample of 1000 mL was studied. From this average sample there were prepared three solutions of different concentrations: 1 % (v/v), 3 % (v/v) and 6 % (v/v) diluted with waste water coming from the waste water treatment plant, whose composition meet the regulation for a wastewater treatment plant. On these samples it has been studied the decreasing of contaminants concentration after the treatment with chemical flocculants: FeSO4 3%, Ca(OH)2 20% and IP114 polyelectrolyte 0.2 ppm. After physical and chemical treatment the highest concentration sample was analyzed, focusing on contaminants biodegradability in contact with biological sludge by biological treatment using a pilot plant. Keywords: oil sludge, biodegradation, contaminants, flocculants
