Title

Survey of Corrosion and Scaling Potential Produced Water from Ilam Water Treatment Plant

English Abstract

Corrosion causes metals delivering (conduit materials) into the conveyed liquid. If the corrosion be very rapid, it will cause pipes cavitation. Then, the intrusion of contaminants into the pipes result in negative suction and if the water has been scaling tendency, a scale layer will introduce, then induce internal scaling and reduce convey potential in pipes. The aim of this research was determining the corrosion potential of produced water in Ilam Water Treatment Plant during 2007 to 2008. For this reason the measures of temperature and pH determined by pH meter model E520 manufactured of Switzerland at site and determining of Total Dissolved Solids, calcium hardness, calcium, total alkalinity and bicarbonate concentration had done in laboratory according to standard method manual. Values of pHs, Langlier Saturation Index, Ryznar Stability Index, Aggressiveness Index, Puckorius Scaling Index and Larson Ratio, calculated twice at month during 12 months between 2007to2008. The calculated results showed that the mean and Standard Deviation values of Langlier Saturation Index, Ryznar Stability Index, Aggressiveness Index, Puckorius Scaling Index and Larson Ratio are equal to 0.29 and 0.5, 7.45 and 0.17, 12.44 and 0.16, 7.99 and 0.14 and 0.77 and 0.1, respectively. By survey of corrosion indexes, it founded that produced water from Ilam water treatment plant has average corrosion potential. By comparing of the quality parameters produced water from Ilam Water Treatment Plant with available standards, it’s founded that the average concentration for Ca++, SO4--, Cl-, TDS, hardness and pH is in the range of Iran and EPA water quality standards.
