Tag: anaerobic digester

Introduction The anaerobic digester gallery is arguably the most complex and hazardous environment within a Water Resource Recovery Facility (WRRF). Engineers are tasked with balancing two volatile forces: the biological/hydraulic requirement to keep sludge moving and heated, and the thermodynamic requirement to safely contain and manage explosive methane gas. A single specification error in either […]

Introduction One of the most persistent operational headaches in municipal wastewater treatment is the gradual failure of anaerobic digester efficiency due to inadequate mixing and poor gas handling. Engineers often find themselves managing digesters that have lost 30-40% of their active volume to grit accumulation and scum blankets, necessitating dangerous, expensive cleanouts that can cost […]
