Upflow anaerobic reactor system.
- It requires little energy for its operation, therefore its operation is low cost.
- Its maintenance is less than an activated sludge reactor since it does not have diffusers.
- Useful for reducing high organic loads to later use an activated sludge process.
- Low sludge production (10% of what MBBR/activated sludge produces).
- Biogas is generated and can be used for the production of electricity or a source of heat for boilers.
