Volume & Moisture Reduction
Wet biosolids are fed into a high-efficiency drying system that rapidly removes moisture.
Thermal Stabilization
The material reaches temperatures and residence times required for Class A pathogen reduction.
Granular Output
The dried product is discharged as a Class A–ready material that is easy to handle and eligible for beneficial use pathways.
