Inclined tube sedimentation tank

The inclined tube sedimentation tank is a highly efficient composite sedimentation tank designed based on the shallow tank sedimentation theory; it is also collectively referred to as a shallow tank sedimentation tank.  Densely packed inclined tubes or plates are installed in the sedimentation area, allowing the 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 down the plates (or tubes) to the bottom of the tank under the force of gravity and is then collectively discharged. This type of tank can increase sedimentation efficiency by 50-60% and enhance 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 raw wastewater, and the use of flocculants is generally required during operation. The inclined tube water purification method involves installing inclined tube components at a 60-degree angle above the sludge suspension layer. The suspended solids and particles in the raw water form flocculated flocs after the addition of coagulants, which 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. The sludge is discharged through the sludge pipe into a sludge tank for further treatment or comprehensive utilization. The clarified water gradually rises and is discharged through the collection pipe, where it can be directly released or reused.
