Various aspects of the present disclosure are directed to sewage treatment plants and methods of operating sewage treatment plants. In one example embodiment, the sewage treatment plant includes a clarifier having an aeration region with a vent opening to blow in oxygenous gas for mixing water to be clarified and a settling region with an outlet. The sewage treatment plant further includes a wall system that delimits the at least one aeration region from the at least one settling region by the wall system. The wall system has a channel system which has at least one first opening leading to the aeration region in the region of the water level and a sludge removal device of the channel system in the region of a lower wall of the clarifier for transporting solids-rich water from the settling region into the aeration region.

Disclosed is a rake-free thickening device including driving area. The device includes a feed assembly, a diversion assembly and a clean coal collection assembly. The clean coal collection assembly includes a driving area. The diversion assembly includes a central tank. Slime water passes through the feed assembly and flows with a medicament from an upper part of the central tank to a middle of the central tank, and then diffuses around. Bubbles carry the fine slime up after reacting. The driving zone drives the dispersed bubbles to a defoaming zone located in the middle of the central tank. The slime water in the central tank flows through the central tank after defoaming. With the continuously filling of slime water, the slime water above the central tank overflows the central tank to the clean coal collection assembly within the diversion and settlement area.

The purification module includes a purification chamber configured to divide the input water stream into a purified water stream fluidly coupled to the purified water outlet and an impure water stream fluidly coupled to the impure water outlet. The purification chamber includes a first hydrophilic surface and a second hydrophilic surface spaced from the first hydrophilic surface. The first hydrophilic surface and the second hydrophilic surface cooperate to establish purified zones of substantially pure water and an impure zone of impurity concentrated water from the input water stream. The purified water stream is supplied by substantially pure water from the purified zones and the impure water stream is supplied by the impurity concentrated water from the impure zone.
