'''Construction of the mixing tank'''

[[Image:]]
| style="border:0.75pt solid #000000;padding:0.071cm;"| Hello everyone and welcome to this Spoken Tutorial on construction of the mixing tank.

This is an activity to be done on Day 2.

|-
| style="border:0.75pt solid #000000;padding:0.071cm;"| '''Slide 2'''

'''Learning Objective'''
We will learn :

* Significance and shape of the mixing tank
* How to fabricate a mixing tank

| style="border:0.75pt solid #000000;padding:0.071cm;"| In this tutorial, we will learn-

* Significance of the mixing tank.
* How to construct a mixing tank.

|-
| style="border:0.75pt solid #000000;padding:0.071cm;"|
| style="border:0.75pt solid #000000;padding:0.071cm;"| Let’s first understand-

The Significance of the mixing tank and shape of the mixing tank.

Show the dimensions on this image
| style="border:0.75pt solid #000000;padding:0.071cm;"| Mixing tank is where biomass is mixed with water and passed into the digester tank.

The mixing tank is usually cylindrical in shape.

| style="border:0.75pt solid #000000;padding:0.071cm;"| A mixing tank of height 2 feet and diameter 22 inches -

* Has the capacity to hold 25 kgs of manure mixed in water.

* However, dry manure should never be put into this tank.

* Manure should always be mixed in equal quantity of water.

|-

| style="border:0.75pt solid #000000;padding:0.071cm;"| * For example, 25 kgs of manure should be mixed in 25 liters of water.
* This will ensure free flow of the biomass into the digester tank.

'''Construction of the mixing tank'''.

Step by step procedure to construct the mixing tank

| style="border:0.75pt solid #000000;padding:0.071cm;"| Let’s see the construction of the mixing tank.

|-
| style="border:0.75pt solid #000000;padding:0.071cm;"| '''Slide 4'''

'''Construction of mixing tank'''

For construction following items are used:

| style="border:0.75pt solid #000000;padding:0.071cm;"| For construction, following items are used-

* Weldmesh sheet- thickness 16 gauge
* Newspaper
* Sand
* Cement
* Liquid waterproofing material

|-
| style="border:0.75pt solid #000000;padding:0.071cm;"| '''Slide 5'''

'''Construction of the mixing tank'''.

Step by step procedure to construct the mixing tank
| style="border:0.75pt solid #000000;padding:0.071cm;"| The Step-by-step procedure to construct the mixing tank is as follows

|-
| style="border:0.75pt solid #000000;padding:0.071cm;"| [[Image:]]

| style="border:0.75pt solid #000000;padding:0.071cm;"| Spread the Weldmesh sheet of 69 inches x 24 inches on the ground.

* Next, at a distance of 34 inches from one end of the sheet
* make a hole of size - 4 inch diameter with a metal cutting scissor.

|-
| style="border:0.75pt solid #000000;padding:0.071cm;"| [[Image:]]

| style="border:0.75pt solid #000000;padding:0.071cm;"| Now tie the loose ends, end to end with steel wire.

We need to make a cylinder like structure with diameter 22 inches and height 24 inches.

|-
| style="border:0.75pt solid #000000;padding:0.071cm;"| [[Image:]]

| style="border:0.75pt solid #000000;padding:0.071cm;"| Note that the hole has to be at the base of the mixing tank.

|-
| style="border:0.75pt solid #000000;padding:0.071cm;"| [[Image:]]
| style="border:0.75pt solid #000000;padding:0.071cm;"| Now, place newspaper or any other paper inside the structure.

The paper will help hold the sand that will be filled inside this structure.

|-
| style="border:0.75pt solid #000000;padding:0.071cm;"| [[Image:]]

| style="border:0.75pt solid #000000;padding:0.071cm;"| Pour sand up till the brim of the structure.

This will give firmness to the mesh while plastering the outer wall.

|-
| style="border:0.75pt solid #000000;padding:0.071cm;"| [[Image:]]

| style="border:0.75pt solid #000000;padding:0.071cm;"| Now, we will plaster the outer wall of the mixing tank.

Prepare cement mixture as follows-
* Sand- 75 kgs
* Cement-25 kgs
* Liquid waterproofing material - 50 ml thoroughly stirred in 10 ltrs of water.
* Adequate water to mix the mixture well

Note- that no gravel is used in this mixture.

|-
| style="border:0.75pt solid #000000;padding:0.071cm;"| [[Image:]]
| style="border:0.75pt solid #000000;padding:0.071cm;"| Start plastering the outside wall of the mixing tank as shown here.

|-
| style="border:0.75pt solid #000000;padding:0.071cm;"| [[Image:]]

[[Image:]]

| style="border:0.75pt solid #000000;padding:0.071cm;"| Finally smoothen the plastering using a wooden trowel.

The mixing tank should be left overnight for curing.

|-
| style="border:0.75pt solid #000000;padding:0.071cm;"| [[Image:]]
| style="border:0.75pt solid #000000;padding:0.071cm;"| Next day, take out all the sand placed inside the mixing tank.

This must be done carefully so as to not break the plastered outer wall of the mixing tank.

|-
| style="border:0.75pt solid #000000;padding:0.071cm;"| [[Image:]]

[[Image:]]

| style="border:0.75pt solid #000000;padding:0.071cm;"| Once the sand is taken out, plaster the inside wall of the mixing tank.

Prepare fresh cement mixture as was prepared for outer wall of the mixing tank.

Spread half inch of this mixture on the inside wall.

While plastering, please remember the position of the hole that is at the base.
We need to break the plaster from here, later.

|-
| style="border:0.75pt solid #000000;padding:0.071cm;"| [[Image:]]

| style="border:0.75pt solid #000000;padding:0.071cm;"| Let the plaster on the inside wall dry for 6-7 hours.

After 6-7 hours, remove the plaster at the position of the hole by slightly tapping it.

|-
| style="border:0.75pt solid #000000;padding:0.071cm;"|
| style="border:0.75pt solid #000000;padding:0.071cm;"| At this point the mixing tank is ready to be transferred to the actual plant site.

|-
| style="border:0.75pt solid #000000;padding:0.071cm;"|
| style="border:0.75pt solid #000000;padding:0.071cm;"| Remember -

The following has to be completed on same day i.e day 2 of civil work

Hence, the mason has to plan accordingly.

|-
| style="border:0.75pt solid #000000;padding:0.071cm;"|
| style="border:0.75pt solid #000000;padding:0.071cm;"| This brings us to the end of this tutorial.

|-
| style="border:0.75pt solid #000000;padding:0.071cm;"|
| style="border:0.75pt solid #000000;padding:0.071cm;"| Assembly of the mixing tank for the Biogas plant will be explained in a later tutorial.
