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: ~48–55 […]
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 […]
FACILITY BASIC INFORMATION Plant Name: Akron Water Reclamation Facility (WRF) Location: 2460 Akron-Peninsula Road, Akron, Summit County, Ohio Operating Authority: City of Akron Department of Public Service, Sewer Bureau Design Average Flow: 90 MGD Peak Secondary Capacity: 220-280 MGD (Hydraulic) Population Served: Approx. 330,000 Service Area: City of Akron and 13 surrounding communities (approx. 96 […]
Introduction One of the most frequent oversight areas in wastewater treatment plant (WWTP) design is the “last mile” of the solids handling process: moving dewatered cake from the centrifuge, belt press, or screw press to its final load-out point. Engineers often spend months optimizing the dewatering device itself, only to treat the conveyance system as […]

Introduction Grit removal represents one of the most abrasive and maintenance-intensive unit processes in municipal wastewater treatment. Engineers and plant superintendents frequently grapple with a critical reliability paradox: while grit capture technologies have advanced significantly, the pumps tasked with transporting that captured slurry to classifiers often remain the weakest link. A single failure in the […]
The authoritative technical resource for the Southerly WWTP infrastructure, operations, and engineering specifications. FACILITY BASIC INFORMATION Plant Name: Southerly Wastewater Treatment Plant (SWWTP) Location: 6977 South High Street, Lockbourne, Franklin County, Ohio Operating Authority: City of Columbus, Department of Public Utilities (Division of Sewerage and Drainage) Design Capacity: 114 MGD (Average Daily Flow), 330 MGD […]
Introduction For municipal and industrial engineers, the “pump” is often treated as a singular asset, yet the success or failure of a pumping station frequently hinges on a single component: the impeller. The rise of non-dispersible solids (flushable wipes) and the demand for higher energy efficiency have created a paradox in modern wastewater design. High-efficiency […]
