Abstract:

This technical report describes the use of a predictive mathematical dispersion model to calculate aerosolization efficiencies and viability losses of wastewater aerosols generated by spray irrigation with treated wastewater. The geometric mean aerosolization efficiency for standard plate count for all the trials analyzed in this study is 1.98 x 10 to the minus 3rd power. The geometric mean aerosolization efficiency for Coliforms determined by the spread plate method on Endo agar is 5.64 x 10 to the minus 4th power and for Coliforms determined by the membrane filter method using m-Endo broth is 2.26 x 10 to the minus 3rd power. The geometric mean aerosolization efficiency for Coliphage F2 is 4.44 x 10 to the minus 4th power compared to a value of 8.10 x 10 to the minus 3rd power for the dye on all trials analyzed in this study. These aerosolization efficiency estimates lead to the following estimates of the viability losses of the biological aerosols 76 percent for standard plate count 93 percent for Coliforms determined by the membrane filter method using m-Endo broth, and 95 percent for Coliphage F2.
