INTRODUCTION One of the most persistent debates in municipal water treatment and tertiary wastewater polishing centers on the choice between proprietary membrane technologies and versatile packaged filtration systems. Engineers are frequently caught between the absolute barrier protection of ultrafiltration (UF) and the robust, forgiving nature of adsorption clarifiers or conventional multimedia filtration. This decision affects […]
Facility Status: Fully Operational | Phase: Major Capital Improvement (Ocean Outfall Legislation Compliance) Facility Basic Information Plant Name: South District Wastewater Treatment Plant (SDWWTP) Location: 8950 SW 232nd St, Cutler Bay, FL 33190 (Miami-Dade County) Operating Authority: Miami-Dade Water and Sewer Department (WASD) Permitted Capacity (AADF): 112.5 MGD Peak Hydraulic Capacity: ~285 MGD Population Served: […]
Introduction One of the most frequent debates in municipal advanced treatment design centers on the selection of tertiary filtration technology. Engineers are often tasked with balancing the stringent pathogen rejection of low-pressure membranes against the energy efficiency and simplicity of depth filtration. This dichotomy is best represented by analyzing DuPont – Memcor vs Aqua-Aerobic for […]
Note to Engineers: While frequently associated with the Union County Utilities Authority (which manages solid waste), the wastewater treatment operations in this jurisdiction are managed by the Rahway Valley Sewerage Authority (RVSA). This technical document focuses on the RVSA wastewater treatment facility. FACILITY BASIC INFORMATION Plant Name: Rahway Valley Sewerage Authority (RVSA) Treatment Plant Location: […]

Introduction One of the most persistent and expensive challenges in wastewater treatment plant (WWTP) operation is the downstream devastation caused by inorganic solids. Pumps with eroded impellers, clogged digestion tanks, and abrasive wear on sludge dewatering equipment cost utilities millions annually in preventable maintenance. Yet, headworks design often suffers from “copy-paste” specifications that fail to […]
1. Introduction The oxidation ditch is a modified activated sludge biological treatment process that utilizes long solids retention times (SRTs) to remove biodegradable organics. Oxidation ditches are typically complete mix systems, but they can be modified to approach plug flow conditions. Ideally suited for small- to medium-sized municipal wastewater treatment plants, these systems are renowned […]
Introduction In the complex ecosystem of municipal and industrial treatment facilities, the “Big Three”—pumps, pipes, and valves—often dominate the initial design conversation. However, the operational success of a plant frequently hinges on the specialized auxiliary equipment that supports the primary treatment train. When engineers search for the Top 10 Other – Other Manufacturers for Water […]
The primary wastewater treatment facility serving Newark and Essex County, New Jersey. FACILITY BASIC INFORMATION Plant Name: Newark Bay Treatment Plant Location: 600 Wilson Avenue, Newark, Essex County, New Jersey Operating Authority: Passaic Valley Sewerage Commission (PVSC) Design Capacity: 330 MGD (Annual Average) Peak Wet Weather Capacity: ~720 MGD Population Served: 1.5 million residents Service […]
Introduction For municipal and industrial wastewater engineers, the protection of downstream process equipment—pumps, valves, centrifuges, and digesters—starts at the headworks. The improper reduction of solids or the inefficient separation of inorganic grit can lead to catastrophic pump cavitation, seal failures, and the rapid accumulation of rag balls in digesters that necessitates expensive cleanouts. When specifying […]
