CLR – Covered Lagoon Reactor

CLR application

The Covered Lagoon Reactor (CLR) is a technology that enables the anaerobic digestion of high volumes of liquid wastewater. Characterised by a very low dry matter content and a low fibre content, the process takes place by recirculating the biomass within a lagoon at controlled temperature and flow rates, in an activated sludge layer. With variable retention times, anaerobic digestion takes place in a psychrophilic or mesophilic thermal regime, depending on the biomasses entering the reactor.

How CLR technology works

The reactor has a very simplified configuration. It is in fact a tank with high volumes, called “lagoon” and provided with a gasometric cover. The digestion volumes are suitable and proportional to the typical high flow rate of industrial processes, to ensure biological stability of the anaerobic digestion.

CLR technology advantages:

  • It enables ON-SITE MANAGEMENT OF HIGH STREAM;
  • It has HIGH BUFFERING CAPACITY IN THE MANAGEMENT OF ACID BIOMASS IN MONODIGESTION;
  • It ensures LOW ENERGY COSTS FOR THE MIXING SYSTEM;
  • It ensures FLEXIBILITY IN THE MANAGEMENT OF SEASONAL BIOMASSES.
