Chemical and Microbiological Analyses of Certain Water Sources and Industrial Wastewater Samples in Egypt

El- Fadaly, M.M. El-Defrawy, F. El-Zawawy and D. Makia

Abstract:
The chemical analyses included quantitative measurement of electrical conductivity, alkalinity, hardness sulphate, pH, total dissolved solids, chloride, as well as dissolved oxygen and BOD were carried out. The microbiological examination for different water sources and industrial wastewater samples was also conducted. Some of heavy metals, Co2+, Cu2+, Fe3+ and Mn2+ were determined in fresh water, while other metals, such as Cr6+, Co2+, Zn2+ and Ni2+ were measured in industrial wastewater. Results of the chemical analysis showed that all measured parameters were found within the limitation either national or international law, except some samples which showed higher values than the permissible limits for some measured parameters. The microbiological analysis exhibited presence of yeasts, fungi and bacteria. Most bacterial isolates were short rod, spore formers as well as coccoid shaped bacteria. The efficiency of water treatment process on the reduction of microbial load was also calculated. Regarding the pathogenic bacteria, data showed that neither water samples nor industrial wastewater contain pathogens when using specific cultivation media for the samples examination. Furthermore, data proved the possibility of recycling of the tested industrial wastewater on which some microorganisms can grow. Data showed also that the percent of heavy metals removal can reach to more than 70% in some cases as a result to bacterial treatment of industrial wastewater.
