Sand Bedding and Anaerobic Digesters

Sand Bedded Dairies

Can you run manure from sand bedded cows through a digester? You can, but you have to consider the impact of the sand on pumps and mixers. The success of the project hinges on the quality of the sand recovery system. In addition, adding a port for robotic sand cleaning is essential to prevent overly frequent digester clean outs. Here at Rapport Renewables, we have helped select sand removal systems and robotic digester cleaning systems. We have also run sandy manure and monitored the impact of sand on the digester. We can also help with modeling of sand removal rates and the impact on gas production.
