Building the walls of the slurry tank [[Image:]] |
Hello everyone.
Welcome to this Spoken Tutorial on building the walls of the slurry tank. This is an activity to be done on Day 2. |
Slide 2
Learning Objectives We will learn:
|
In this tutorial, we will learn-
|
Slide 3
What is a slurry tank? |
Let’s first understand what is a slurry tank. |
Image |
Slurry-
|
Slide 4
Position of the slurry tank? |
Let’s look at the position of the slurry tank with respect to the Biogas plant. |
Image |
The slurry tank is placed in line with the entrance of the dome. |
Slide 5
Shape of the tank? |
What is the shape of the tank? |
Image |
These tanks are rectangular in shape. |

|
What you see here is the pictorial representation of the slurry tank.
2. The small tank is enclosed within the upper tank. |
|
Notice- 1. The pink colored walls of the smaller tank-
2. Also note, the upper tank has an outlet hole 3. The lower tank is in line with the entrance to the digester tank |
Slide 6
How many walls have to be constructed for building the slurry tank? |
So, in total, how many walls have to be constructed for building the slurry tank? |
Image |
Total 7 walls have to be constructed to build the slurry tank
|
Image |
Items used for construction are-
|
Image |
To begin with, insert the 3 steel rods through the holes of the chicken mesh. |
|
Insert these steel rods through sufficient number of holes.
This will ensure that the rod will not slide while placing it on the cement plaster. |
|
Next, lay a plastic sheet on the ground. |
|
Use a measuring tape to mark boundary for-
|
|
We will spread the cement mixture within this boundary, on the plastic sheet. Prepare cement mixture as follows-
Note- that no gravel is used in this mixture. |
|
To begin with, first, spread 1.5 inch thickness of the cement mixture. Spread it between the boundary of the wall. |
|
Now carefully- 1. Place the chicken mesh with inserted steel rods on this cement mixture. 2. This chicken mesh with inserted steel rods serves as-
|
Care should be taken to- 1. Leave an extra 4-5 inches of chicken mesh at either sides of each wall. 2. This will be entwined or interlocked-
3. Doing this will help fixing the walls of the slurry tank with the dome. | |

In the earlier two images, we saw-

Slide 7 Significance of a hole in one of the walls of the slurry tank. |
Now let’s talk about the significance of this hole. |
[[Image:]]
[[Image:]] |
It is this hole from where- 1. the slurry smoothly comes and 2. flows out to the agricultural field. |
Slide 8
How to make a hole in the wall of the slurry tank? |
So how to make this hole in the wall of the slurry tank? |
|
To make a hole-
|
[[Image:]] [[Image:]] [[Image:]] |
To begin with:
2. Then insert the Steel rods as explained earlier-
3. Now lay this mesh with a hole-
4. The thickness of this cement mixture should be 1.5 inches. |
|
Exactly on this hole-
2. Before placing it, please remember-
3. Importantly-
|
|
|
Now, spread cement mixture around the pipe, using the small trowel.
| |
Note that the pipe will be removed when the cement is dry. | |
[[Image:]] |
After the pipe is removed, this is how the hole would look like. |
[[Image:]] |
The prepared walls are left for drying for two days and will be used on day 4. |
This brings us to the end of this tutorial | |
Assembly of the walls of the tank will be explained in a later tutorial. | |
