How does tube settler work?
We are going to find out tube settler working principle now. A tube settler is made up tubular channels that are placed adjacent to each other. These are placed at 60 degrees and combined to increase the effective settling area of particles. The settling area of the particles is made in such a way that it is less deep than that of the conventional clarifier. This makes it easier for the floc to settle very easily. For the tube settler to arrest the fine particles, it has to make use of the fine floc that manages to go past the clarification zone. In this case, it makes the larger particles to reach the bottom of the tank in a better shape. The tube settler now creates a sizeable mass that can go down the channel with ease.
Tube settlers work in 2 ways;
First, they provide a large surface area for settlement of particles. This is because of the angle at which they are joined.
Secondly, they are used to accumulate the smaller particles until they form larger particles that can move down the pathway uniformly.
Tube settlers are common in rectangular clarifiers, where they increase the settling surface area of particles. This works by means of increasing the vertical distance the particle will have to move before settling.
By the use of parallel tubes, tube settlers make upward water movement to be uniform.
Is there any difference between tube settlers and plate settlers?
Is there any difference between tube settlers and plate settlers?
Yes, there are many differences which we are going to look into. Tube settlers are not like any other water treatment methods. They are easy to install and portable too.
Tube Settler Advantages
It is made of PVC lightweight material. This makes it easily portable.
They can be fitted in different sizes and shapes in tanks. This is because of their lightweight and portability.
