I always searching new techniques to produce biogas from animal and kitchen organic waste at house level in urban area, mostly biogas digester in the world are floating dome and fixed dome type biogas digester, these plant need large space and large quantity of organic waste. It can not build in urban area, I found on internet some
portable biogas plant like ARTI biogas plant and GREENTECH biogas plant these plant work fine, I inspired by ARTI biogas plant design so decide to make my on digester similar as ARTI plant.
See ARTI Biogas Plant Diagram source Pakistan Science Club forum
ARTI Biogas plant is very simple and useful biogas plant can be made by
plastic, steel tank, and bricks ARTI biogas plant consist on two part
1st is digester tank
2nd is Gas older tank,
Digester tank also called fermenter where fermentation of manure takes place and biogas produces. Digester tank is made by 1000 liter water tank and gas holder made by 750 liter plastic water tank.
PVC pipe also use as inlet and outlet.

Here a links visit http://paksc.org/pk/biogas-plant-design/...-tank.html
When I was arranging material of digester I thought alternative of gas holder tank because it cost and extra working for cutting etc, so I decide alternate of gas tank to Old or used Tyre tube of tractor or large tube of Tyre. In this storage system I got two benefits, first I saved 3000 Rp and 2nd gas can be transfer.
Here is Photos of Step by Step Digester construction I hope you will learn and try to make.
Components of the Bio-gas Plant.
The main components of the biogas Digester are a digester tank (Water Tank), an
inlet (PVC Pipe) for feeding the kitchen waste, gas storage tank (Tyre Tube), an outlet for
the digested slurry and the gas Pipe.
Material List Of Biogas Plant.
- 700 liter water Tank ( used as Digester Tank)
- 3 Inch Diameter and 3 fit in length PVC pipe (to be used as inlet pipe)
- 3 Inch Diameter and 2 fit in length PVC pipe (to be used as out let pipe)
- PVC Pipe adapter (to be used as funnel).
- Iron nipple
- Two PVC Pipe Caps
- Two Elbow
- Plastic pipe 5 ft (to be used for delivery of gas)
- Gas Valve
- Supper glue (to be used for fixing of pipe)
- Sand
Tools required
A hack saw blade for cutting the pipes and a soldering iron cutting holes on the tank
Step 1
Here are some photos of biogas plant tank and components.

Step 2 Making of inlet Pipe.
I take PVC pipe and put on side of tank and make circle with the help of pencil it should be equal to PVC pipe diameter.

| Inlet pipe and outlet pipe fitted in tank |
 |
| fix the elbow with outlet pipe |
 |
| Make hole on cap of water tank and fix the iron nipple in it |
Step 3

| Final Product of portable Biogas Plant |
(
Note: Tyre tube not showing in this post it will be show on an other post with working of plant ) PVC cap will use at inlet and outlet pipe to hold back pressure
of gas.
After two or three hours of wait to allowing all joints to get cured and become leak proof
Initially, cow-dung mixed (with the ration of 50 % water and 50 % dung )will be fed in to the system, which anaerobically bacteria will start the gas formation . After a week gas tube filled with biogas, but this gas not burnable because of the quantity of methane gas has very low and other gases like carbon dioxide nitrogen and sulphide gas. afterward, you can use food waste, decomposable organic material and kitchen waste it should be diluted with water.

Please guide me how much quantity is use for first time to fill and empty area 700 Liter tank. please tell the ratio to fill, and after how many days fill again.
yar is ka muje complete tariqa kar urdu me send karan mera e mail hae sajid_meyo@yahoo.com
hi
how do you do calculation for the product gas from anaerobic digestion ,or it is no calculation
ex: if you have 1m3 from animal wastes ,and you want to calculate the gas product from the digester how calculate it
and how you control the gas and measuring
