1. INTRODUCTION In the hierarchy of unit processes within municipal and industrial wastewater treatment facilities, solids conveyance systems often receive less design scrutiny than liquid stream biological processes. However, the mechanical transport of dewatered biosolids, screenings, and grit represents one of the most mechanically intensive and maintenance-critical operations in a treatment plant. The failure of […]

Introduction In municipal and industrial water treatment, the reliability of process analytics—pH, conductivity, dissolved oxygen, and turbidity—often hinges not on the sensor electronics, but on the mechanical interface with the process stream. A surprising 25% of premature sensor failures in wastewater applications are attributed to improper mounting, poor flow dynamics at the insertion point, or […]
