      <abstract xml:lang="ru">
        <p>Рассматривается поведение флокулированной суспензии в сгустителе-осветлителе с использованием одномерной пространственной модели. Данная модель сочетает теорию процесса осаждения-сжатия флокулированной суспензии, которая описывается строго вырожденным диффузионным уравнением с разрывами потока, происходящими в системе сгуститель–осветлитель. Построение профиля концентрации производится для непрерывно работающего сгустителя-осветлителя. Приводятся численные примеры построения профилей концентрации для установившего режима и их использование для сравнения различных режимов работы.</p>

        <p>The present paper is devoted to the research of a spatially one-dimensional model of flocculated suspensions in the clarifier–thickener. This model unites a theory of sedimentation– consolidation processes of flocculated suspensions, which leads to a strongly degenerate diffusion equation, with the discontinuous flux. The development of steady-state concentration pro- files in a continuously operated clarifier-thickener is described. Numerical examples for construction of steady-state profiles and their applications for comparisons different modes of operation, to the control of sediment height are presented.</p>
