The steady-state compartment description of the biological reactors and settlers in wastewater treatment plants that is used in SimpleTreat has been evaluated with respect to an alternately operated WWTP situated in Roskilde, Denmark. The effect of substituting a complex discontinuous operation, involving alternating degradation and flow conditions between two reactors, with one single biological reactor with continuos flow (SimpleTreat) has been investigated by setting-up two models representing the respective operation schemes. An experimental series was performed where inlet, outlet, primary sludge and secondary sludge samples were taken and analysed for phthalates, nonylphenols and LAS. Generally the modelled half-lives for the phthalates were low and the removal efficiencies of the nonylphenols and phthalates were high compared to literature values. The results from the modelling work concludes that it is possible to substitute a complex alternating operation with a system containing one single biological reactor, corresponding to SimpleTreat, when a suggested empirical aggregate 1st order degradation rate is employed
