摘要：Inactivation of viruses has been an insuperable inhibition to the use of recycled water. Substantial success in solving the problem has recently been achieved using a hot column evaporator (HBCE). Here we extend the technique to inactivate E. coli and MS2 viruses in different electrolyte solutions (0.17M NaCl and 0.01M CaCl2). An increase in the inlet air temperature, from 103 to 250 °C, substantially improved the destruction of both pathogenic groups in either solution. E. coli proved to be more susceptible than viruses to inactivation in the HBCE. The phenomenon of inhibition of bubble coalescence above 0.17M for the NaCl solutions makes the HBCE process for this solution more efficient than for CaCl2 solutions. In part, this is because of the higher air/water interfacial area with NaCl.
