In these types of plants, mainly cattle dung (now other wastes are also being used) is used as the feed material. (iv) These plants are not suited for small farms/farmers who do not have sufficient raw materials and resources. The same gas storage can be linked to each tank in turn.

However, this can be over come by building a series of tanks and staggering the loading so that production from one tank will overlap the other. (ii) The spent damp material will still be fibrous as digestion does not break down the lignin, and will require further processing (turning) to create favorable conditions for aerobic bacteria. (i) Although the liquid contents are drained away before unpacking, fumes of ammonia remain which could be harmful to health. (iv) When a batch fed digester is used in combination with a continuously fed biogas plant on a farm, each could be fed different raw materials and produce the same end products. (iii) Where the biogas and bio-fertilizer producing requirement is strictly connected with a campaign period or where the availability of raw materials is seasonal and the gas is required in quantity for drying grains, a batch-fed plant serve the purpose. (ii) Many diverse materials can be used e.g., corn stalks, leaves, bagasse from sugar mills and milling wastes from wheat, rice and other grains. (i) They require little or no daily attention. The main advantages of batch fed plants are: There are mainly two types of designs of biogas plants : In our country, mainly single stage digesters are built. In the two-stage digesters, the second tank acts as a storage and solid stabilization tank, while the first tank is designed to provide optimum conditions for gasification. The differences between the two, is mainly in the degree of control of the environmental factors, this design, may be single вЂ“ stage or two stage system. The size of these plants is recommended up to 6 m 3 per day.ДЄnaerobic fermentation systems may be of standard or high rate design.

The biogas from this type of biogas plants are used by the individual family. This type of biogas plants are installed at individual family level. The size of these plants is recommended also to be more than 15 m 3 per day. The biogas produced from these plants is used for the respective institution. These types of biogas plants are installed by an institution such as religious institution like Gurudwara/Mandir/Gowshala or educational institution like School/College. The size of theses plants is recommended to be more than 15 m 3 per day. The biogas produced from this type of plant is distributed to the people living in that locality. These types of plants are installed by a Village Panchayat/Municipal Committee for any Village/Mohalla/Town/City. It is a plant to be used by a group of people as a community. The biogas plants are mainly classified into three classes Vii) Gas outlet, pipe, gate valve, gas distribution pipeline, water trap, fittings, gas stove, lamp and similar appliances which can run on biogas. Iii) Gas holder or gas storage masonry dome It would also help to maintain anaerobic condition in the digester.ДЄ biogas plant consists of the following parts:

Ii) A gas holder to collect biogas, so formed by fermentation in the digester. The outlet would also control to constant volume of slurry in the digester. I) A digester or fermentation tank with an inlet and outlet chambers for the entry of fermentable mixture (cow dung and water in 1:1 ratio) in the form of slurry into the digester and exit of digested slurry. This biogas plant consists of mainly two parts: The biogas plants in India were mostly popular by the name of gobar gas plant and these plants were of Khadi and Village Industries Commission ( KVIC ) design. Initially cow dung was mainly used as fermentable material for the production of biogas. The whole system in which anaerobic fermentation of cellulose containing organic material takes place and produces biogas, which accumulates in the gasholder or the dome, then utilization of this gas through the gas pipeline under suitable pressure is called biogas plant system.
