1. INTRODUCTION The trickling filter is one of the oldest and most established biological treatment processes in municipal and industrial wastewater applications. Classified as an attached-growth (or fixed-film) process, a trickling filter operates by passing wastewater over a stationary medium—historically rock or slag, but increasingly structured plastic modules—where a biofilm establishes itself. This biomass metabolizes […]
Introduction For municipal and industrial treatment plant engineers, solids handling frequently represents the most volatile component of operational expenditure (OPEX). While the liquid train often receives the bulk of design attention, the “tail of the plant”—sludge thickening, dewatering, and disposal—accounts for approximately 40% to 50% of total treatment costs. When evaluating the Top 10 Sludge […]
Introduction In the modern municipal water and wastewater landscape, the System Integrator (SI) occupies a critical role that transcends simple equipment supply. Unlike pump manufacturers or valve suppliers who provide discrete mechanical assets, the SI is responsible for the facility’s central nervous system—the Supervisory Control and Data Acquisition (SCADA) system, Programmable Logic Controllers (PLCs), Human […]
Introduction For municipal and industrial wastewater engineers, the decision to implement Moving Bed Biofilm Reactor (MBBR) or Integrated Fixed-Film Activated Sludge (IFAS) technologies usually stems from a singular, pressing constraint: the need to increase biological treatment capacity within a fixed, often land-locked footprint. While the concept of biofilm carriers is well-established, the “commodity” perception of […]
The authoritative technical resource for the Philadelphia Water Department’s primary energy-neutral facility. FACILITY BASIC INFORMATION Plant Name: Southeast Water Pollution Control Plant (SE WPCP)Location: 25 Pattison Avenue, Philadelphia, PA 19148Operating Authority: Philadelphia Water Department (PWD)Design Capacity: 121 MGD (Average Daily Flow)Peak Hydraulic Capacity: 224 MGDPopulation Served: ~1,000,000 residentsService Area: South Philadelphia, Center City, and portions […]
Introduction One of the most persistent challenges in municipal and industrial water treatment design is the fragmentation of technology. A typical treatment plant is a complex assembly of headworks, biological processes, clarification, disinfection, and solids handling systems. When engineers treat these as isolated unit processes, the facility often suffers from integration failures, disparate control philosophies, […]
Location: Orlando, Orange County, FloridaOperating Authority: Orange County Utilities (OCU)Design Capacity: 24.0 MGD (Annual Average Daily Flow)Treatment Level: Advanced Wastewater Treatment (AWT) / 100% Water Reuse 1. Introduction The Eastern Water Reclamation Facility (EWRF) serves as a cornerstone of water resource management for the rapidly expanding eastern sector of Orange County, Florida. Operated by Orange […]
Introduction to Tertiary Filtration Selection For municipal and industrial engineers, the tertiary filtration stage is frequently the final safeguard between regulatory compliance and permit violations. As National Pollutant Discharge Elimination System (NPDES) permits tighten—particularly regarding total phosphorus (TP) limits of < 0.1 mg/L and strict turbidity requirements for Title 22 water reuse—the margin for error […]
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 […]
