Studies On the Optimizing Conditions of Concentration Viruses in Water

It is very important to optimize the operating conditions of virus concentration from water body for evaluating virus’s pollution and removing efficiency. In this paper, an optimizing method of virus concentration from water body was established. It was to adopt the way of throwing clay of Na-montmorillonite in water sample in advance, in order to increase the ability of viruses precipitation because of their adsorption to the clay, then choose a good quality flocculating agent of poly chlorination aluminum and optimize the operating conditions of precipitating the suspend solid of Na-montmorillonite. The rate of recoved viruses from different water bodies of Min River water, domestic sewage and drinking water were higher than 84.3% to PV1, TMV and the phage of E coli by this concentration method. It can give a way of simplicity, high viruses recovery rate and low cost viruses concentration method.
