Abstract

A biosolids treatment process and system are described. The process includes a thermophilic digestion step (1), a methane generation step (2), and a mesophilic disgestion step (3). Optionally, the process also includes a first stage solids dewatering step (4). Optionally, the process also includes an evaporative drying step (5).
