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 […]
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 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 […]
FACILITY BASIC INFORMATION Plant Name: Westerly Wastewater Treatment Center (WWTC) Location: 5800 Cleveland Memorial Shoreway, Cleveland, Cuyahoga County, Ohio Operating Authority: Northeast Ohio Regional Sewer District (NEORSD) Design Average Capacity: 35 MGD Peak Wet Weather Capacity: 400 MGD (Combined Plant & CSOTF) Population Served: ~106,000 residents Service Area: Cleveland (West Side), Brooklyn Heights, Cuyahoga Heights, […]
INTRODUCTION Grit removal efficiency is often the silent variable that dictates the lifespan of downstream biosolids equipment, clarifier drives, and digesters. While the civil design of grit chambers (vortex vs. detritor vs. aerated) garners significant attention during the design phase, the mechanism for extracting that captured grit—the grit pump—is the common failure point. Engineers often […]
FACILITY BASIC INFORMATION Plant Name: Mill Creek Wastewater Treatment Plant Location: 1600 Gest Street, Cincinnati, Hamilton County, Ohio Operating Authority: Metropolitan Sewer District of Greater Cincinnati (MSDGC) Design Capacity: 120 MGD (Dry Weather) / 360+ MGD (Wet Weather Peak) Current Average Flow: ~100 MGD Population Served: ~800,000 residents (Regional system total) Service Area: Central Cincinnati […]
Authoritative Technical Resource for The Woodlands, Texas Wastewater Infrastructure FACILITY BASIC INFORMATION Plant Name: SJRA Woodlands Division Wastewater Treatment Plant No. 1 (Flagship Facility) & Regional System Location: 2436 Sawdust Rd, The Woodlands, Montgomery County, Texas Operating Authority: San Jacinto River Authority (SJRA) – Woodlands Division Combined Permitted Capacity: 20.1 MGD (System Total) Plant No. […]
1. Introduction In municipal and industrial wastewater treatment, the management of residual solids—commonly referred to as sludge handling—represents one of the most complex and cost-intensive portions of the plant lifecycle. While the liquid treatment train often garners the primary focus regarding effluent compliance, the solids handling train dictates operational efficiency, disposal costs, and often the […]
