Disclosed is a sedimentation tank system including high-rate filtration part and being capable of primary treatment of sewage and wastewater, flow rate adjustment, and treatment of wetweather flow. According to an aspect of the present disclosure, there is provided a sedimentation tank system for removing solids in an influent sewage and wastewater, the sedimentation tank including a filtration part which includes a filter medium and removes solids in the influent sewage and wastewater, a sedimentation tank with a water gate formed at a predetermined height to store sewage and wastewater flowing over the water gate, and an outflow distribution channel that receives, from the filtration part, sewage and wastewater from which solids have been removed, and discharges the same to the outside of the primary sedimentation tank.

Some embodiments of the technology disclosed herein relate to a system having a hydrodynamic separator element defining an element inlet and an element outlet. The element outlet has a first element outlet and a second element outlet. The hydrodynamic separator element has a plurality of curved microfluidic channels in fluid communication. Each of the plurality of microfluidic channels are arranged to operate in parallel. Each microfluidic channel defines a channel inlet downstream of the element inlet and a channel outlet having a first channel outlet upstream of the first element outlet and a second channel outlet upstream of the second element outlet. A flow characteristic sensor is in sensing communication with the separator element. A controller is in data communication with the flow characteristic sensor, where the controller is configured to provide a first alert upon the flow characteristic being outside a first threshold.

A system for treating wastewater comprising a coagulation-flocculation assembly having a raw wastewater inlet and a coagulated-flocculated wastewater outlet; and a slurry separator comprising an intake area configured for receiving wastewater slurry from the coagulated-flocculated wastewater outlet, a liquid outlet, a sludge outlet, and a filtration module configured to facilitate percolating of liquid therethrough and forming of a filter cake thereon. The slurry separator being configured to receive slurry at the intake area, separate the slurry to liquid and sludge by the filtration module, remove the liquid via the liquid outlet, and convey the sludge from the intake area to the sludge outlet. The system further comprises a level maintaining arrangement configured to maintain at least a minimal level of the filter cake.

This invention belongs to the field of wastewater treatment technology, specifically a multi-stage adjustable-angle high-density sedimentation tank and its working method. It includes a sedimentation tank body, which comprises a water-holding tank with an inlet fixedly inserted through its side wall. By adjusting the movement of the bottom of the adjusting plate, the inclination angle of the inclined plate formed by the adjusting plate and the first rotating plate is reduced. A displacement ring adjusts the angle of the inclined plate in real time according to the water density, allowing the inclined plate to adapt to changes in water density, thereby improving sedimentation efficiency, reducing the amount of coagulant added, or extending the retention time, thus reducing wastewater treatment costs. Furthermore, by the float slowly descending synchronously with the water level, the water is kept in a relatively static or low-velocity state, while the local velocity changes caused by the movement of the second rotating plate are small, reducing disturbance during scraping and thus helping to ensure stable effluent quality.
