This system ensures the removal of rag and grits from the biosolids before they are removed from site. This allows more options for disposal of the biosolids via beneficial reuse solutions without the concern of contamination within the final product and avoids the need to take the material to landfill. We have maintained a minimum 20% solids content for all material processed through our new mobile centrifuge which has ensured safe and efficient transport solutions when disposing from site.
NPE’s proven methods for emptying anerobic digesters ensures the material is mixed and uplifted from the tanks efficiently and safely without damage to the digester, allowing the digesters to be cleaned and returned to service in the shortest amount of time possible. This drastically reduces the operating pressure on the plant by avoiding lengthy downtime for our clients so that their digesters are returned to service quickly and back to full operating capacity.
