INTRODUCTION Grit accumulation remains one of the most pervasive and costly “silent failures” in municipal wastewater treatment. While headworks screens provide visible capture, grit often bypasses preliminary treatment, settling in aeration basins, reducing digester capacity by up to 30%, and causing premature abrasion failure in downstream pumps. For consulting engineers and plant directors, the selection […]

1. Introduction In the municipal and industrial water and wastewater sectors, gas detection is not merely an ancillary safety function; it is a critical operational imperative mandated by rigorous regulatory frameworks and necessitated by the inherent chemistry of the treatment process. The decomposition of organic matter, chemical dosing requirements, and the physical constraints of underground […]
Introduction In the municipal and industrial water sector, data integrity is the bedrock of process control. Yet, a surprisingly high percentage of plant alarmsβestimated by some automation audits to be over 40%βare nuisance alarms caused not by process failures, but by instrumentation drift, fouling, or improper specification. For the design engineer or plant superintendent, the […]
FACILITY BASIC INFORMATION Plant Name: Jackson Pike Wastewater Treatment Plant Location: 2104 Jackson Pike, Columbus, Franklin County, Ohio Operating Authority: City of Columbus, Department of Public Utilities (Division of Sewerage and Drainage) Design Capacity: 68 MGD (Average Daily Flow) / 102 MGD (Peak Secondary) / 150 MGD (Peak Hydraulic with CEPT) Current Average Flow: ~60-65 […]
Introduction The movement of dewatered biosolids, screenings, and grit is often the final bottleneck in modern treatment facilities. While headworks and biological processes receive significant engineering attention, the conveyance of “cake” solids remains a frequent source of operational headaches, from housekeeping nightmares to complete mechanical failures. Engineers tasked with facility upgrades often face a critical […]
The authoritative technical resource for the Great Miami River’s primary wastewater defense. FACILITY BASIC INFORMATION Plant Name: City of Dayton Water Reclamation Facility (DWRF) Location: 2800 Guthrie Road, Dayton, Montgomery County, Ohio Operating Authority: City of Dayton Department of Water Design Capacity: 72 MGD (Average Daily Flow), 200 MGD (Peak Hydraulic) Current Average Flow: ~48β55 […]
1. Introduction to Thickening Equipment in Water and Wastewater Treatment In the hierarchy of unit processes within municipal and industrial wastewater treatment facilities, sludge thickening represents a critical intermediate step between liquid treatment and solids handling. While often overshadowed by the biological treatment processes upstream or the final dewatering and disposal downstream, thickening is the […]

Selecting the Right Wastewater Management System for Your Municipality Assessing Current and Future Wastewater Needs Municipalities must accurately assess both current and future wastewater needs to select an effective wastewater management system. This assessment is best for municipalities experiencing rapid growth or those with fluctuating industrial activities. Evaluating Population Growth Projections Population growth projections are […]
