Bonjour à tous !
J'ai rédigé ce texte expliquant le procédé de traitement de l'eau, j'aimerais avoir vos avis s'il vous plait
Nowadays, we have a big problem about our energy consumption. Indeed, we are searching for others renewable energy. I would also talk about biogases energy. What is it and how does it works ? There are questions I’ll answer.
The biogas is approximately 65% methane and 35% carbon dioxide and several other gases of low concentrations. Biogaz is only coming from organic waste. Firstly Agricultural waste and other organic waste are collected and passed through a fodder mixing trailer or in a hygenisation pit. Then wastes are brought to a biogas digester: We call it a digester because it is a large tank filled with bacteria that eats organic waste and gives a flammable gas : the biogas. The main parts of the biogas process is the cogenerator : Cogeneration is the production of electricity and heat out of biogas.
The cogeneration module consists of an engine which actuates an alternator.
The recovery of heat makes it possible to reach a total output of 85% if all produced heat is used. Finally we can use this energy for electricity or heating.
In United Kingdom a bus run with human dejections, it is funny and ecologic.
The biogas represents a real opportunity for us to use renewable energy and to preserve our planet.
