In this article, the authors analyzed the known and modern methods of obtaining biogas, their advantages and disadvantages, and proposed a method and installation for cleaning biogas from harmful impurities: hydrogen sulfide, CO2 and water vapor. In laboratory units studied the main process parameters: the compositions of nutrient medium, stirring speed (to remove the cork education and improve metabolism), stop, and loading of fresh substrate supply for methanogenic bacteria, and pH.
