Abstract

Contamination in drinking water is the most common form of environmental problems encountered in water resources management. Some contaminants, present accidentally in drinking water, are very difficult to remove, such as heavy elements that are products of industrial waste. Strontium is one of the most difficult-to-remove elements. This paper proposes a novel process for removal of strontium compounds contaminants from water. The proposed method shows great efficiency. The technique uses thermophilic bacteria found in the United Arab Emirates near Al-Ain town located in Abu-Dhabi Emirates. These bacteria were isolated and used in a reactor coupled with a membrane system. The bacteria, the stirrer and the membrane housed in the reactor are arranged in a distinctive way to form the novel bio-stabilization process proposed in this research. This proposed technique could be used at low cost and with great confidence in the purification of drinking water. The system was found to be adequate for concentrations of strontium in the range of 5-30. ppm. At the end of the operation the strontium concentration reaches the level allowed by the World Health Organization regulations.
