FACILITY BASIC INFORMATION Plant Name: Moccasin Bend Wastewater Treatment Plant (MBWWTP) Location: 455 Moccasin Bend Road, Chattanooga, Hamilton County, Tennessee Operating Authority: City of Chattanooga, Waste Resources Division Design Capacity: 140 MGD (Hydraulic); ~78 MGD (Secondary Biological) Current Average Flow: ~60-70 MGD […]
Introduction In the specification of wastewater treatment physical separation equipment—specifically secondary clarification, gravity thickening, and grit removal systems—engineers often reach a critical decision point that dictates plant reliability for decades. The choice frequently boils down to two distinct philosophies: the standardized, process-optimized approach typical of major global OEMs (like Evoqua/Xylem) versus the heavy-duty, custom-fabrication approach […]
INTRODUCTION One of the most persistent challenges in municipal and industrial treatment plant design is the “Proprietary vs. Custom” dilemma. Engineers frequently encounter this when selecting equipment for specialized unit processes—such as high-rate clarification, tertiary filtration, or anaerobic digestion auxiliaries. A surprising statistic from lifecycle audits reveals that while proprietary high-rate systems can reduce civil […]
Nitrification and Denitrification: Essential Processes for Nutrient Removal In the quest for cleaner water and sustainable wastewater management, understanding the nitrification denitrification process is crucial. These two interconnected biological processes play a vital role in the nitrogen cycle, helping to convert harmful ammonia into less toxic forms while significantly improving effluent quality. In this post, […]
1) INTRODUCTION UV disinfection systems are frequently over-simplified during the preliminary design phase as “pipes with lights,” leading to significant operational headaches down the line. A common challenge engineers face is distinguishing between conventional UV reactor designs and newer optical technologies when high-level pathogen log removal (e.g., Adenovirus) or difficult water matrices are involved. Statistics […]
The authoritative technical resource for the Northwest Water Reclamation Plant. FACILITY BASIC INFORMATION Plant Name: Northwest Water Reclamation Plant (NWWRP) Location: 990 W. 8th Street, Mesa, Maricopa County, Arizona Operating Authority: City of Mesa Water Resources Department Design Capacity: 18.0 MGD (Liquid Stream rated capacity) Current Average Flow: ~10-12 MGD Population Served: Approx. 150,000+ (Northwest […]
Introduction Liquid storage and containment are fundamental to the integrity of any treatment plant or distribution network, yet they are often treated as static commodities rather than dynamic process vessels. For municipal consulting engineers and utility directors, the failure of a storage tank represents more than just a leak; it signifies a catastrophic breach of […]
The authoritative technical resource for the engineering and operational details of Pima County’s central wastewater asset. FACILITY BASIC INFORMATION Official Name: Agua Nueva Wastewater Reclamation Facility (Agua Nueva WRF) Former Name: Roger Road Wastewater Reclamation Facility Location: 2947 W. Calle Agua Nueva, Tucson, Pima County, Arizona Operating Authority: Pima County Regional Wastewater Reclamation Department (RWRD) […]
INTRODUCTION In the realm of anaerobic digestion and cogeneration, the protection of downstream assets—whether internal combustion engines (ICE), boilers, or renewable natural gas (RNG) membranes—is paramount. Engineers often face a critical disconnect: the anaerobic digester produces valuable fuel, but that fuel is laden with hydrogen sulfide (H2S), siloxanes, and moisture that can destroy capital equipment […]
