Introduction One of the most frequent points of failure in decentralized wastewater treatment is the misalignment between the chosen technology and the operational reality of the municipality. Engineers often design for steady-state compliance, overlooking the fact that small-to-mid-sized plants—ranging from 0.05 to 2.0 MGD—often face the most volatile hydraulic loading and the leanest staffing levels. […]

INTRODUCTION One of the most persistent debates in the small-to-medium wastewater treatment sector centers on the selection of sequencing batch reactor (SBR) technologies versus continuous flow loop variations. Specifically, when engineers evaluate Aqua-Aerobic vs Aero-Mod for Packaged Treatment Plants: Pros/Cons & Best-Fit Applications, they are essentially choosing between two distinct philosophies of hydraulic management and […]
1. Introduction Water softening is a critical unit process in both municipal water treatment and industrial process water preparation. It addresses the presence of dissolved calcium, magnesium, and other polyvalent cations that constitute “hardness.” For municipal consulting engineers and utility decision-makers, the selection of water softening systems is rarely a simple procurement exercise; it is […]
Introduction In municipal and industrial wastewater treatment, volume reduction is the single most effective method for controlling downstream costs. By thickening Waste Activated Sludge (WAS) from a typical 0.5–1.0% solids concentration to 5–7%, facilities can reduce the hydraulic volume sent to digesters or holding tanks by up to 85%. However, selecting the right equipment to […]
FACILITY BASIC INFORMATION Plant Name: Belmont Advanced Wastewater Treatment Plant (AWTP) Location: 2700 South Belmont Avenue, Indianapolis, Marion County, Indiana Operating Authority: Citizens Energy Group (Citizens Wastewater of Westfield, LLC) Design Capacity: 300 MGD (Peak Secondary Treatment), 120 MGD (Average Design) Current Average Flow: ~100-110 MGD Population Served: Approx. 800,000+ (Indianapolis/Marion County Metro) Service Area: […]
1) INTRODUCTION In the design of municipal water and wastewater infrastructure, the management of fluid dynamics and headspace containment represents a critical intersection of hydraulics, structural engineering, and environmental control. One of the most frequent trade-off analyses engineers face—particularly in surge control and storage applications—involves choosing between active pressurized containment and passive atmospheric covering. This […]
