Dry fermentation refers to the anaerobic digestion in airtight sealed digesters, of organic solids with up to 40 percent dry matter. The digestion of biomass forms high quality biogas with a high methane and low hydrogen sulphide content.The digestion process is more efficient and less energy consuming than wet digestion processes. Any organic solid mass that can be tipped, such as biowaste, cuttings and solid manure with up to 40 percent dry matter can be used. Furthermore, no sorting of interfering material or pre-treatment is required.
Methania innovative dry digestion solution enables biomass to be utilised with minimum effort and energy. In our biomass systems, the digestion process is divided between individual digesters where the biomass is digested under exclusion of air.
Sewage gas emerges during wastewater treatment and sewage sludge digestion. the biogas contain high level of H2S and contaminants. Which is removed by treatment process upstream of CHP plant.From 6m3 of sewage, CHP systems menage to generate on average 1 KWh of electric power and 1.2 KWh of thermal energy.
Methania offers a complete system including digesters desufulurization systems, gas holders, filters, compression, piping and automation in plus of CHP and boilers.
Landfill BiogasThe Landfill gas produced by the anaerobic decomposition of organic matter in the deposited refuse has to be captured and removed for environmental reasons. It thus constitutes a virtually free source of energy thant can be utilized to generate power using Methania solutions. In addition to the financial benefits, Landfill gas valorisation systems offers the following additional advantages.• Reduction of odor nuisance from Landfill sites • Prevention of dangerous smoldering fires • Avoidance of gas migration • Optimization of the Landfill sites’s recultivation process.
