Study of physiochemical parameters and the heavy metals for the treated sewage water in Misurata

Abstract

Samples of sewage water have been collected from Misurata 'station that is being located out of the city from the southern area in Alseket area in order to study the physio chemical parameters for the treated sewage water The samples have been collected from August to January 2010 immediately from the gathering center ٫ one sample for 3 bis over six months period. The study included measuring and estimating the electrical connection (EC), pH, TDS, and the total content of the heavy metals. Some of the were detected and the results showed that the treated sewage water in Misurata consists of some heavy metals like (NA, K, Ca, Mg). All of the tested elements in the treated sewage water were less the internationally allowed limit through the six months of the year. Except the cadmium and iron elements which were above the internationally allowed limit. The physio-chemical parameters for the treated sewage water from the purification plant in Misurata and the one used in the irrigation of the public agricultural sekt project and the one that has irrigated the agricultural feed. project. They show an increase in the electrical connection value for the treated sewage water samples. They reached its highest value in January ms/cm 4460.0000. And reached its less value mS/cm 1338.2667 in October with a total average of mS/cm3730.2526. And the total salinity reached the highest value for the total dissolved salts in the treated sewage water 2899.3333mg/liter in January and the less value 2495.6667 Mg/liter in September. The average of total salinity through the studied six months is 2697.7895mg/liter The pH for the treated sewage water tends to be base since it fluctuates in a narrow limit around the general average that reached 7.9967mg/liter throughout November.
