Inclined plate sedimentation tank and inclined tube sedimentation tank each have their own advantages and disadvantages. Choosing which one is better depends on the specific application scenario and needs.
Inclined plate sedimentation tank:
Advantages:
High sedimentation efficiency: The setting of the inclined plate increases the sedimentation area, shortens the sedimentation distance of the particles, and improves the sedimentation efficiency.
Small footprint: When treating the same amount of water, the area required for the inclined plate sedimentation tank is relatively small.
Low energy consumption: It mainly relies on gravity to precipitate suspended matter, and does not require a lot of energy.
Simple operation and maintenance: The structure is relatively simple, and the operation and maintenance are relatively convenient.
Strong adaptability: It is suitable for different types of water quality and treatment requirements.
Disadvantages:
High requirements for coagulation: A better coagulation effect is required to achieve the ideal sedimentation effect.
Sludge discharge problem: The operation is complicated when discharging sludge with multiple buckets, and the mechanical scraping equipment is prone to rust.
Easy to scale and grow biofilm: It is easy to scale and breed biofilm after a period of use, affecting the sedimentation effect.
Poor buffering capacity: The buffering capacity for changes in water quality and water volume is weak.
Inclined tube sedimentation tank:
Advantages:
High sedimentation efficiency: The specific surface area of the inclined tube filler is large, which improves the sedimentation efficiency.
Strong processing capacity: Suitable for treating wastewater with high suspended matter or oil.
Strong anti-clogging ability: The pipe diameter is small, suitable for treating wastewater with high suspended matter, but a matching backwashing system is required.
Disadvantages:
High price: The cost of the inclined tube filler is high.
Easy to age: It is easy to age when exposed to ultraviolet light for a long time, and anti-UV agents need to be added to extend its life.
High maintenance cost: Regular maintenance and replacement of fillers are required.
Application scenarios
The inclined plate sedimentation tank is suitable for scenarios with limited space and high processing capacity requirements, such as small and medium-sized sewage treatment plants or occasions where water quality needs to be treated efficiently.
The inclined tube sedimentation tank is suitable for treating wastewater with high suspended matter or oil, such as electroplating, chemical and other industrial wastewater treatment.
