Factors influencing the adsorption of bacteria to magnetite in water and waste water

The adsorption of bacteria to a magnetite preparation used in a new water clarification process has been studied. It was found that bacteria adsorbed rapidly and in large numbers to magnetite. Adsorption was best in the range pH 3-6 in the absence of calcium and magnesium, but the range was extended...

Description
Summary:The adsorption of bacteria to a magnetite preparation used in a new water clarification process has been studied. It was found that bacteria adsorbed rapidly and in large numbers to magnetite. Adsorption was best in the range pH 3-6 in the absence of calcium and magnesium, but the range was extended to pH 10 in the presence of these two cations. These cations also interfered with the desorption of bacterial cells. The adsorption of bacteria from a wastewater was also studied.
