UASB is a wastewater treatment process that uses anaerobic reactors to remove organic matter and produce biogas. In these reactors, an anaerobic sludge blanket forms inside the reactor, which consists of a mixture of biomass and organic matter. The sludge blanket retains solid particles and promotes the anaerobic decomposition of the organic matter present as the effluent passes through the reactor.
During the anaerobic decomposition process, microorganisms convert organic matter into biogas, composed mainly of methane (CH4) and carbon dioxide (CO2). This biogas can be captured and used as an energy source to generate electricity or heat.
- Among the main advantages of the system we have:
- Efficient process for removing high-load organic matter;
- Supports load variations;
- Low energy cost, as it does not require aeration or oxygen supply.
