FACILITY BASIC INFORMATION Plant Name: Virginia Initiative Plant (VIP) Location: Norfolk, Virginia (4201 Powhatan Avenue) Operating Authority: Hampton Roads Sanitation District (HRSD) Design Capacity: 40.0 MGD (Hydraulic) Peak Hydraulic Capacity: 80.0 MGD Population Served: Approx. 200,000+ (Norfolk, sections of Virginia […]
1. Introduction In the context of municipal and industrial water and wastewater treatment, aeration blowers represent the single most critical active component in the biological treatment process. They serve as the “lungs” of the plant, delivering the necessary oxygen to microorganisms within activated sludge basins, membrane bioreactors (MBR), and aerobic digesters. From an energy standpoint, […]
The authoritative technical resource for the City of Columbia’s flagship treatment facility. FACILITY BASIC INFORMATION Plant Name: Metropolitan Wastewater Treatment Plant (Metro WWTP) Location: 1200 Simmon Tree Lane, Columbia, Richland County, South Carolina Operating Authority: Columbia Water (City of Columbia) Design Capacity: 60 Million Gallons per Day (MGD) Current Average Flow: ~32-38 MGD Population Served: […]
Introduction The safety and structural integrity of anaerobic digesters rely entirely on the precise management of internal pressures. For decades, the specification of gas safety equipment has largely been a binary choice in the North American market. Engineers evaluating Varec Biogas (Ovivo) vs Shand & Jurs for Digestion applications are navigating a landscape defined by […]
Introduction to Ozone System Engineering Ozone generation is one of the most chemically potent yet operationally complex technologies in the water treatment arsenal. Unlike UV or chlorination, ozone is generated on-site, requiring a sophisticated integration of power supply, gas preparation, cooling thermodynamics, and mass transfer mechanics. For municipal and industrial engineers, the challenge is rarely […]
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. […]
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 […]
