Methanogenic bacteria are inactive at very high or low temperatures. Methanogenic are the special microorganisms that help to produce Biogas.
The disadvantages of the biogas generators is that it is not attractive commercially and it is not feasible to locate all the location. The advantages is that it provides a non-polluting and a renewable source of energy.
One advantage of biogas is that it is a renewable source of energy. It also has environmental benefits. One disadvantage is that it is not a cheap process in comparative terms to other biofuels.
if the water temperature is too hot it will burn the scalp, if the water temperature is too cold it will not clean the scalp.
From trash to gas
Pros: * Can be used in natural gas facilities * Cheap technology * renewable source Cons: * Still pollutes * Long production time * Smaller energy output than natural gas * needs 'cleaning', has a lot of impurities
Biogas production can help reduce greenhouse gas emissions by capturing methane that would otherwise be released into the atmosphere from organic waste. This can help mitigate climate change. However, biogas production requires energy for processing and transportation, and there can be environmental impacts associated with land use for feedstock production.
The optimal ratio of carbon to nitrogen for biogas production is typically around 25:1 to 30:1. This ratio is important for efficient microbial fermentation in the anaerobic digestion process, where microorganisms break down organic materials into biogas. A balanced C:N ratio helps ensure proper decomposition and biogas yields.
Composting and biogas production are similar in that they both involve the breakdown of organic materials by microorganisms to produce nutrient-rich byproducts. While composting produces compost for soil amendment, biogas production generates methane gas for energy use. Both processes help reduce waste and contribute to a more sustainable approach to managing organic materials.
Requirements for biogas production include having an expert who will be familiar with the needs of the digester as well as access to associated manure handling equipment and gas utilization components.

When you run on biogas added no new carbon dioxide to the atmosphere. You can say that the vehicles run on solar energy, which is first bound in green plants, and finally converted into biogas. Biogas are therefore called "carbon neutral". Biogas does not contribute to global warming and climate change. This makes biogas to fuel alternatives today with the least impact on the environment. Biogas is a part of the natural cycle. Biogas is formed during decomposition of organic material in oxygen-free environment. The gas is formed spontaneously in nature in the sumpgas, or controlled in a Sewage digesters. When biogas production, we take to be the waste from the slaughter and food and manure from the farm, ie a kind of recovery. From biogas extraction we also biogödsel replacing chemical fertilizers in agriculture. Since biogas is a renewable energy has an important part of the sustainable society that we must strive to achieve. SRINIVAS KASULLA srinivaskasulla@gmail.com
AFAIK, Yes. The theory is though that whatever produced the biogas in the first place cancels out the pollution caused when the gas is used. Don't take this for fact though, look at catalytic converters as an example. They reduce SOME pollution but what do they cause ;)
Biogas typically contains methane (around 50-70%), carbon dioxide (around 30-50%), and small amounts of other gases such as hydrogen sulfide, water vapor, and nitrogen. The exact composition can vary depending on the feedstock and the efficiency of the biogas production process.
The density of biogas can vary depending on the composition of gases present, but on average it is around 1.2 kg/m^3 at standard conditions of temperature and pressure.
Oxygen can disrupt the anaerobic digestion process in a biogas generator by promoting aerobic bacteria growth, which can reduce the production of methane gas. Keeping oxygen away helps maintain an anaerobic environment necessary for the efficient decomposition of organic matter and the generation of biogas.
This would entirely depend on how efficient your biogas consuming electrical generator is and what the constituent gases in the biogas are. Biogas can contain between about 50-70% methane. The available energy in the biogas is derived from the calorific value (CV) of methane factored by the concentration of methane in the biogas. If you know the efficiency of the gas engine then you can derive the energy output from the known CV of the biogas input. It is important to select a suitable generator that can run on biogas and will provide suitable warranties when operating on biogas. It may be necessary to consider the impact of contaminant gases such as siloxanes, hydrogen sulphide and moisture in the biogas. It may be appropriate to protect the engine by installing scrubbing systems to clean the gas and remove the contaminants upstream of the engine in order to improve the lifetime of the equipment.
