Homemade Medium size Biogas Plant for Kitchen waste.

Homemade Medium size Biogas Plant for Kitchen waste Final Product of portable Biogas Plant 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 plantlike 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. Construction of ARTI Biogas Plant step by step Video Portal Here a links visit http://paksc.or g/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. 1.700 liter water Tank ( used as Digester Tank) 2.3 Inch Diameter and 3 fit in length PVC pipe (to be used as inlet pipe) 3.3 Inch Diameter and 2 fit in length PVC pipe (to be used as out let pipe) 4.PVC Pipe adapter (to be used as funnel). 5.Iron nipple 6.Two PVC Pipe Caps 7.Two Elbow 8.Plastic pipe 5 ft (to be used for delivery of gas) 9.Gas Valve 10.Supper glue (to be used for fixing of pipe) 11.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. All Components of Homemade portable Biogas digester 700 liter water tank to be used as Digester Tank 700 liter water tank and other Material for making of Plant 700 liter water tank and other Material for making of Plant Elbow, PVC Adopter Pipe, Glue, Valve 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. PIPe and Tank Drawing a circle around PVC pipe on top side of the water tank Drawing a circle around PVC pipe on one side of the water tank Circle showing on top side of tank making of hole with help of soldiering Iron making of hole with help of soldiering Iron almost done making of hole with help of soldiering Iron making of hole with help of soldiering Iron fitting of pipe inside the hole Inlet PVC pipe fitted it shouldn't attach with bottom Cut the extra length of PVC pipe (should be equal to the tank cap) making of hole with help of soldiering Iron side of the tank for outlet pipe. PVC Pipe Adopter fix on Pipe 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 sealed the joint of pipe with tank by supper glue and sand Inlet system of biogas plant 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 pressureof gas. After two or three hours of wait to allowing all joints to get cured and become leak proof Feeding Of Digester TankInitially, 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.
