средство для разделения по крайней мере нижней части флотационного резервуара и фильтрующей среды на множество проходящих в вертикальном направлении отсеков;
средство, расположенное в каждом отсеке, выполненное с возможностью гидравлического сообщения с фильтрующей средой в соответственном отсеке;
первое средство, соединенное со всеми отсеками, выполненное с возможностью отвода осветленной и профильтрованной воды из первых выбранных отсеков через упомянутое средство гидравлического сообщения;
средство для хранения первого фильтрата;
второе средство, соединенное со всеми отсеками и средством для хранения первого фильтрата, для направления первой фильтратной воды и фильтрующую среду и из нее в по крайней мере втором выбранном одном из отсеков через упомянутое средство гидравлического сообщения;
средство для обратной промывки фильтрующей среды в по крайней мере одном из отсеков первой фильтратной водой, текущей в упомянутый по крайней мере один отсек из упомянутого второго средства и
клапанное средство для каждого отсека, присоединенное между упомянутыми первым и вторым средствами с возможностью изоляции первой фильтратной воды от осветленной воды, причем клапанное средство выполнено с возможностью избирательного соединения средства с фильтрующей средой в упомянутом выбранном одном из отсеков в соответствии с обратной промывкой.1. A clarifier containing an inlet for untreated water with particulate contaminants, a flotation tank, where contaminants are flocculated by a chemical added to the incoming water, and floated by microscopic air bubbles to the surface of the water in a flotation tank, where they form a floating layer sludge, a layer of filter medium located in the lower part of the flotation tank, for filtering water before it is fed to the outlet for clarified water and a means for removing pop-up sludge from the tank and its direction to the outlet for the sludge, characterized in that it contains:
means for separating at least the bottom of the flotation tank and filter medium into a plurality of vertically extending compartments;
means located in each compartment, made with the possibility of hydraulic communication with the filtering medium in the respective compartment;
first means connected to all compartments, configured to drain clarified and filtered water from the first selected compartments through said hydraulic communication means;
means for storing the first filtrate;
second means, connected to all compartments and means for storing the first filtrate, for directing the first filtrate water and filter medium to and from it in at least a second selected one of the compartments through said hydraulic communication means;
means for backwashing the filter medium in at least one of the compartments with first filtrate water flowing into said at least one compartment from said second means and
valve means for each compartment connected between the first and second means to isolate the first filtrate water from clarified water, the valve means being configured to selectively couple the means to the filter medium in said selected one of the compartments in accordance with the backwash.
