Ohio Wastewater Utility Achieves Effective Biosolids Management and Asset Optimization Using Advanced Anaerobic Digestion

Introduction

The Kenneth W. Hotz Water Reclamation Facility (KWH WRF) located in Valley city, Medina, south of Cleveland, Ohio, USA, treats 9 MGD (34 mld) of wastewater serving a population equivalent of 250,000 pe.
