| Hello everyone and Welcome to this Spoken Tutorial on Assembly of the Biogas plant.

|-
| 00:10
| In this tutorial, we will learn how to assemble the following

|-
| 00:16
| Digester tank with the dome

|-
| 00:18
| Mixing tank and

|-
| 00:21
| Slurry tank

|-
| 00:23
|Please note that this is an activity of Day 3.

|-
| 00:30
| Let us start

|-
| 00:32
| Transfer the chicken mesh dome to the actual plant site.

|-
| 00:38
| Place the dome on the raised wall of the digester tank.

|-
| 00:43
| Once this is done, fix the main gas pipe of 1 inch diameter, on the top of the dome.

|-
| 00:53
|To do this-- Hold the pipe with the external thread on the top.

|-
| 01:00
|Insert the pipe between the holes of the 3 chicken layer(s) and rotate slightly.

|-
| 01:10
|Check if it is firmly placed.

|-
| 01:13
|The pipe will be fixed permanently in this position when the outer wall of the dome will be plastered.

|-
| 01:24
|Remember: the external thread on the gas pipe, will help fit the hose pipe firmly.

|-
|01:33
| Notice the external thread at the top of the gas pipe.

|-
| 01:38
| An important thing to be done, next, is the following-

|-
| 01:44
| On the side of the dome adjacent to where the mixing tank will be placed-

|-
| 01:51
| Make a firm base, this base should be 4 feet and 5 inches higher than the dome for placing the mixing tank.

|-
| 02:06
| Next, on the side of the dome facing the base of the mixing tank cut chicken mesh

|-
| 02:16
| Use a scissor to cut the mesh and make a hole of 6 inches diameter.

|-
| 02:27
|Through this hole, one end of the inlet pipe will be inserted at an angle of 45 degrees.

|-
| 02:38
|Rest the other end of the inlet pipe at the base of the mixing tank and plaster it with cement mixture.

|-
| 02:52
| Bio-waste will reach the digester tank through this inlet pipe.

|-
| 03:00
| This is how the inlet pipe will look like from inside the dome.

|-
| 03:09
| Once the gas pipe is fitted, we need to plaster the dome from outside.

|-
| 03:18
|An interesting fact is that the dome is plastered twice and both coats of plaster have different ratio of sand and cement.

|-
| 03:35
| For first coat of plastering, use the following-

|-
| 03:42
| Sand- 200 kgs

|-
| 03:45
| Cement- 100 kgs

|-
| 03:50
| Liquid waterproofing material- 150 ml thoroughly mixed in 20 Ltrs of water and adequate amount of water

|-
| 04:04
| What you see here, is the mason using the first coat of plaster, on the dome.

|-
| 04:13
| Before entirely plastering the outer wall of the dome - the base of the Digester tank has to be plastered for the second time.

|-
| 04:27
| Ratio of cement mixture to be used is-

|-
| 04:33
|Sand -90 kgs

|-
| 04:37
| Cement -50 kgs

|-
| 04:42
| Liquid waterproofing material- 100 ml mixed in 15 Ltrs of water and

|-
| 04:53
|Adequate amount of water as mentioned earlier.

|-
| 05:00
|What you see here, is the mason adding Liquid waterproofing material to the cement mixture.

|-
| 05:11
| Remember - The thickness of the layer of the plaster should be about 3 inches only.

|-
| 05:22
| Next comes the attaching of the walls of the slurry tank with the dome.

|-
| 05:30
|Hole of the Slurry tank has to be 6 inches lower than the dome.

|-
| 05:38
|This will ensure free flow of slurry into the slurry tank.

|-
| 05:47
| Place the slanting wall(s) of the slurry tank at either sides of the entrance to the dome.

|-
| 05:58
| With the hook, interlock the excess chicken mesh at the base of the dome and at the edge of the slurry tank wall

|-
| 06:12
| Carefully, tighten the chicken mesh securely, so as to join the walls to the dome.

|-
| 06:23
| To seal the joints, use cement mixture with adequate amount of water.

|-
| 06:34
| Apply this mixture carefully so that there are no gaps at all.

|-
| 06:44
| Please note that at this point, we have used 3 of the 7 walls for the slurry tank.

|-
| 06:57
| The plastered dome should now be left for 6-8 hours for curing.

|-
| 07:06
| Leaving the dome for curing, we will now attach the mixing tank.

|-
| 07:15
|As mentioned earlier- Mixing tank will be placed 4 feet and 5 inches higher than the dome to avoid water logging.

|-
| 07:29
| The mixing tank is connected to the digester tank via the Inlet pipe.

|-
| 07:37
|Before placing, check the hole at the base of the mixing tank.

|-
| 07:44
|The hole should be placed just in front of the inlet pipe of 6 inch diameter.

|-
| 07:52
|Remember - This inlet pipe of 6 inch diameter has been already inserted inside the dome at an angle of 45 degrees.

|-
| 08:08
| For the hole of the mixing tank and the inlet pipe to be in line with each other, do the following-

|-
| 08:20
|Place three bricks around these two and plaster it with cement.

|-
| 08:29
| After plastering, leave it for curing overnight.

|-
| 08:35
| This is how it will look in a functional Biogas plant -

|-
| 08:43
| Now, plaster the entire outer dome wall for the second time and the inner wall of the dome.

|-
| 08:57
| Prepare the cement mixture as follows-

|-
| 09:03
| Sand- 180 kgs

|-
| 09:06
| Cement- 100 kgs

|-
| 09:11
|Liquid waterproofing material- 250 ml mixed in 20 Ltrs of water

|-
| 09:21
|And adequate amount of water

|-
| 09:26
| Spread this mixture evenly on the outer wall of the dome.

|-
| 09:33
| And on the inner wall of the dome, as well.

|-
| 09:39
| Smoothen out the plaster by using the wooden trowel.

|-
| 09:46
|Leave the whole structure for curing for 17 days.

|-
| 09:54
| This brings us to the end of Day 3

|-
| 10:00
| On day 4, we will do the following-

|-
| 10:06
| Dig two rectangular pits adjacent to the side walls of the lower tank.

|-
| 10:15
| The dimensions would be 1 foot and 5 inches of length, 1 foot and 5 inches of width and 2 feet of height

|-
| 10:32
| Dig another pit at the front of the lower tank as shown here

|-
| 10:41
|The dimensions would be, 10 inches of length, 28 inches of width and 2 feet of height

|-
| 10:58
| Lay foundation on both the adjacent sides and the front side of the lower tank using gravel, cement and sand mixture.

|-
| 11:18
| The gravel, sand and cement is mixed in the same proportion as mentioned previously.

|-
| 11:30
|Now, join the four walls of the upper slurry tank.

|-
| 11:37
|Plaster the edges of the walls with cement.

|-
| 11:45
| The wall with the hole should face the fields, this will help the slurry to flow out smoothly through the hole.

|-
| 11:59
| Coming back to the dome, Place approximately 25 jute gunny bags on the dome.

|-
| 12:11
|Twice a day, start spraying water on the dome.

|-
| 12:18
|Spray as much is required to wet the outer wall of the dome.

|-
| 12:26
|Jute bags placed on the outer wall help to retain the water.

|-
| 12:35
|This will keep the dome wet for longer hours.

|-
| 12:43
| Lastly, the entire dome should be covered with the plastic sheet held between 2- 4 pillars.

|-
| 12:56
| This plastic sheet will protect the dome from too much sunlight thereby avoiding too much drying of the dome

|-
| 13:11
| This brings us to the end of Day 4

|-
| 13:17
| On the 15th day of curing-

|-
| 13:22
| Make a mixture of 2 Litres of water,

|-
| 13:29
|250 gms of Synthetic Resin Adhesive and 2kgs of white cement.

|-
| 13:41
|Apply this mixture on the inside of the digester tank, to seal crack(s), if any.

|-
| 13:52
| At this point, the civil work of the biogas plant is completed.

|-
| 14:00
|We will now learn to connect the main gas pipe to the kitchen.

|-
| 14:07
| Connect the main gas pipe from the digester tank to the main gas control valve, as shown here.

|-
| 14:22
|The joint between the main gas pipe and gas control valve should be perfectly air-tight.

|-
| 14:35
|Otherwise, gas leakage from this joint cannot be stopped easily.

|-
| 14:46
| From the main gas control valve, we have to connect a gas conveyer pipe.

|-
| 14:57
|Once again, connect these using a straight joint and ensure it is air-tight.

|-
| 15:11
| The gas conveyer pipe extends all the way to the kitchen.

|-
| 15:20
| Inside the kitchen, connect the safety valve to the gas conveyer pipe using a straight joint.

|-
| 15:33
|Connect another straight joint on the other end of the safety valve.

|-
| 15:43
|Make sure that all the joints are air-tight.

|-
| 15:50
| Lastly, connect the rubber hose to the stove.

|-
| 15:58
|After all the connections are made, the biogas plant is ready for use.

|-
| 16:09
| After 17 days of total curing time, raw materials can be put into the biogas plant.

|-
| 16:23
| Initial production of biogas will take about 6 days.

|-
| 16:31
|After that, it will be a regular daily production.

|-
| 16:38
| Now how to check whether Biogas has been produced ? do the following

|-
| 16:48
|Ensure that both the safety valves are in open position for the gas to be conveyed.

|-
| 17:00
|Light the burner and check the flame for production of the biogas.

|-
| 17:10
| Another issue is water condensation , So how can water condensation can be avoided

|-
| 17:23
| The gas conveyer pipe from the dome towards the kitchen should be always in an upward direction.

|-
| 17:35
|If so, water accumulation inside the conveyer pipe is negligible.

|-
| 17:44
| This brings us to the end of this tutorial

|-
| 17:50
| Let us Summarize-

|-
| 17:54
| In this tutorial, we will learn how to assemble the following

|-
| 18:02
| Digester tank with the dome

|-
| 18:06
