Ozone treatment for Biogas Facilities
Biogas facilities often use manure and meat scraps to produce biogas. The clean methane gas is then piped into the natural gas grid, where it is subsequently used to heat houses and properties.
What is Biogas?
Biogas is a mixture containing primarily methane and carbon dioxide. The gas is produced when microorganisms break down organic material in the absence of oxygen. The process occurs in natural environments and is one of nature's ways of breaking down biomass into smaller constituent parts for reuse in the cycle of nature.
Ozone – an important part of the solution
The retting process used in biogas facilities produces sulphur compounds, such as hydrogen sulphide and mercaptans, which smell awful.
High concentration ozone generation is used to solve the problem. When the clean oxygen is passed through the discharge field in the ozone generator a proportion of the oxygen is transformed into ozone.
The ozone is then introduced into a long pipe that acts as a reaction chamber. An exhaust fan sucks out the foul smelling gasses from the large receiving tank for manure and meat scraps and into the pipe. Which is where the ozone and the gasses meet. As they travel down the reaction chamber, the foul smelling gasses are broken down.
