UNASSIGNED: @entity3265 sanitization is a promising technology for sanitizing @entity1 excreta intended for use as a fertilizer in agriculture. Ascaris eggs are the most persistent pathogens regarding @entity3265 inactivation and are commonly present in fecal sludge in low- and middle-income countries. In this study, a model for predicting @entity3265 inactivation of ascaris eggs was developed. Data from four previous studies were compiled and analyzed statistically, and a mathematical model for the treatment time required for inactivation was created. The inactivation rate increased with @entity3655 activity to the power of 0.7. The required treatment time was found to decrease 10-fold for each 16    C temperature increase. @entity62 ( @entity62 ) content and pH had no direct effect on inactivation, but had an indirect effect due to their impact on @entity3655 activity, which was estimated using the Pitzer approach. An additional model giving an approximation of Pitzer @entity3655 activity but based on the Emerson approach, @entity62 content and total @entity3265 (NHTot) was also developed. The treatment time required for different log10 reductions of ascaris egg viability can thus easily be estimated by the model as a function of @entity3655 activity and temperature. The impact on treatment time by different treatment options can then be theoretically evaluated, promoting improvements of the treatment e.g. by adding @entity1133 or alkaline agents, or increasing the temperature by solar heating.
