INTRODUCTION Managing water age in distribution systems remains one of the most persistent challenges for municipal engineers. With the rising prevalence of chloramines and stricter regulations on Disinfection By-Products (DBPs), the “fill and forget” approach to distribution design is obsolete. Historically, manual flushing was the primary mitigation strategy, but rising labor costs and the need […]
1. INTRODUCTION In the hierarchy of unit processes within municipal and industrial wastewater treatment facilities, solids conveyance systems often receive less design scrutiny than liquid stream biological processes. However, the mechanical transport of dewatered biosolids, screenings, and grit represents one of the most mechanically intensive and maintenance-critical operations in a treatment plant. The failure of […]
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 A frequent point of friction in municipal water and wastewater design lies in the disconnect between specifying distinct industrial components and specifying integrated application solutions. Engineers often grapple with a critical choice: should the control system be built around a global industrial powerhouse platform, or a specialized water-centric integration solution? This dilemma is perfectly […]
Introduction For municipal and industrial plant engineers, the selection of primary disinfection and oxidation technologies often comes down to a fundamental trade-off: the chemical power of ozone versus the physical simplicity of UV. When evaluating Ozonia vs Atlantium Gas Safety Equipment Equipment: Comparison & Best Fit, the conversation extends far beyond the generation unit itself; […]
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 […]
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 […]
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 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 challenges in municipal and industrial water engineering is not the pipe itself, but the integrity of the connections, adaptations, and restraints. Industry statistics suggest that over 60% of pipeline failures occur at joints or fittings rather than along the pipe barrel. For consulting engineers and plant directors, overlooking the […]
