Inclined tube sedimentation tank, excellent solid-liquid separation effect, high automation.

The SHGC inclined tube sedimentation tank is an efficient combined sedimentation tank designed based on the shallow tank sedimentation theory; it is also collectively referred to as a shallow tank sedimentation tank. In the sedimentation zone, numerous densely arranged inclined tubes or plates are installed, allowing suspended impurities in the water to settle within the inclined plates or tubes. The water flows upward along the inclined plates or tubes, while the separated sludge slides downward under gravity along the inclined plates (or tubes) to the bottom of the tank, where it is collected and discharged. This type of tank can improve sedimentation efficiency by 50–60% and increase processing capacity by 3–5 times within the same area. Inclined tube sedimentation tanks can be designed for different flow rates based on experimental data from the raw wastewater, and coagulants are generally added during use. The inclined tube water purification method involves installing inclined tube modules at a 60-degree angle above the sludge suspension layer. This allows the flocculated矾花 formed by suspended solids and particulate matter in the raw water after coagulant addition to accumulate into a thin sludge layer on the bottom surface of the inclined tubes. The sludge then slides back into the sludge suspension layer under gravity and settles into the sludge collection hopper. It is discharged through the sludge discharge pipe into a sludge tank for further treatment or comprehensive utilization. The clarified water gradually rises to the collection pipe and is discharged, either for direct release or reuse.

Device Features
1. It can be used for single-stage or multi-stage pretreatment of various types of wastewater, eliminating the need for additional investment in building sedimentation tanks and reducing the labor intensity of sludge removal.
2. It can directly treat certain single-type wastewaters and meet national standards.
3. It can also perform multi-stage deep purification to achieve compliance in one step.
4. It can be integrated with processes such as wastewater treatment equipment, ultrafiltration equipment, and oxidation devices for advanced treatment.

Application Scope
This device is widely used in industrial wastewater treatment and domestic sewage treatment, non-ferrous metal processing wastewater treatment, hydraulic ash removal wastewater from power plants and boiler rooms, gas station scrubber water treatment, biochemical water treatment, and as preliminary pretreatment and secondary sedimentation for production wastewater and water purification in various mechanical factories.
