| 00:00 | Hello. Welcome to this spoken tutorial on Material required to construct a biogas plant |
| 00:09 | In this tutorial, we will learn about the various materials required to construct a biogas plant |
| 00:18 | Area required to construct the plant |
| 00:22 | The Site, No. of days required for construction and the best time to construct the plant |
| 00:32 | Let us begin. The materials required to construct a biogas plant can be procured from any hardware & cement shop. |
| 00:44 | The following materials are required to construct the plant: |
| 00:49 | Cement 14 packs |
| 00:51 | Gravel – half brass |
| 00:55 | Sand - 1 brass |
| 00:57 | 3 bundles of chicken mesh, 30 feet each |
| 01:02 | Weldmesh sheet of size 3 feet x 4 feet with 1 inch x 1 inch of the hole size |
| 01:11 | 12 feet of 6 mm steel rods, 35kgs |
| 01:18 | 1 kg of steel wire to be cut into 7-8 inches per piece |
| 01:27 | Bricks 3, 2kg of white cement |
| 01:31 | 1 kg of lime powder |
| 01:34 | Jute gunny bags 25 Approximately |
| 01:38 | Plastic sheet- 13 feet x 10 feet and |
| 01:43 | 7 Bamboo sticks of approximate size - 3.5 feet |
| 01:49 | Liquid waterproofing material - 1 Litre |
| 01:53 | Wooden square trowel with a concave bent from inside |
| 01:58 | These are especially used for smoothening the cement plaster on the dome of the Biogas plant |
| 02:06 | Metal square trowel |
| 02:08 | Shovel |
| 02:09 | Small trowel, Hook |
| 02:12 | Trough with a capacity of 10 kgs |
| 02:16 | Scissor to cut the chicken mesh |
| 02:18 | One Measuring tape |
| 02:20 | 1kg of Newspaper |
| 02:23 | Scale with two hooves at the two ends and |
| 02:28 | An Iron rod with hollow ends at the either sides |
| 02:33 | We will now look at other items required to built the plant such as tubes, pipes and valves |
| 02:45 | We required main gas control valve of size 1 inch, metal pipe to be connected from the center of the dome, 30 cms x 1 inch of diameter |
| 03:01 | This will be the main gas pipe |
| 03:04 | Gas conveyer pipe of 1/2 inch diameter |
| 03:08 | The length of this pipe will depend upon the distance between Biogas plant and the kitchen |
| 03:17 | Inlet pipe connected from Mixing tank to Digester tank should be 6 inches diameter and approximately 5 feet of length |
| 03:30 | Another outlet pipe of 6 inches diameter to be connected from slurry tank to the slurry collection pit |
| 03:39 | If the outlet pipe is not required alternately, construct a drain between slurry tank and the slurry collection pit as shown |
| 03:52 | The depth of this slurry collection pit can be between 4 to 6 feet |
| 04:00 | The slurry collected in this pit can be manually poured in the fields |
| 04:06 | We also required a safety-valve of 1 inch |
| 04:11 | Approximately, 6 metres of rubber hose pipe of ½ inch diameter. |
| 04:19 | This rubber hose pipe will be used to convey the gas from the safety valve to the kitchen stove. |
| 04:27 | 2 Vohj clips are require to secure the pipe. |
| 04:32 | A few other items like Synthetic Resin Adhesive 250 ml and Teflon tape |
| 04:42 | Always use good quality cement, gravel and sand. |
| 04:48 | These are really important for the durability of the biogas plant. |
| 04:54 | Let’s now talk about the- Area, Site, No. of days required for construction and best time to construct the plant |
| 05:06 | To construct the biogas plant, we need approximately 12feet X 8 feet of land, near the house. |
| 05:16 | The site should be such that construction cost is minimized and it receives ample sunlight to maintain the right temperature inside the biogas plant. |
| 05:31 | The selected site should also ensure easy operation and maintenance of Mixing tank, Digester tank, Main gas control valve to switch off gas inflow and the Slurry tank |
| 05:49 | The site should also be located near to the source of animal dung and the toilet. |
| 05:57 | This will help to easily operate the plant and avoid wastage of raw materials. |
| 06:06 | The total no. of days required to complete the civil work of a biogas plant are 3 to 5 days. |
| 06:17 | The best time of the year to construct the biogas plant is between November and June. |
| 06:27 | Constructing biogas plants during the rainy season is best avoided, as it becomes messy. |
| 06:36 | This brings us to the end of this tutorial on the material required to construct a Biogas plant. |
| 06:45 | The construction part of the Biogas plant will be explained in next tutorial under the same series |
| 06:55 | Let’s Summarize |
| 06:57 | In this tutorial, we learnt The material required to construct a biogas plant |
| 07:06 | Area required to construct the plant |
| 07:09 | Preferred site and |
| 07:12 | No. of days required along with the best time to construct the plant |
| 07:19 | This video was created by Spoken Tutorial Project with inputs from Rural-ICT team, IIT Bombay. |
| 07:29 | More information on these projects can be found at these links. |
| 07:36 | This is Bella Tony along with the animation team of the Spoken Tutorial project signing off.
