Introduction to PC Pump Intake Hydraulics One of the most persistent and expensive failure modes in municipal wastewater treatment plants involves the premature destruction of progressive cavity (PC) pump stators. While often blamed on “bad rubber” or manufacturing defects, a significant percentage of these failures are actually hydraulic issues rooted in the civil and mechanical […]
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 […]
Introduction Grit removal represents one of the most abrasive and maintenance-intensive unit processes in municipal wastewater treatment. Engineers and plant superintendents frequently grapple with a critical reliability paradox: while grit capture technologies have advanced significantly, the pumps tasked with transporting that captured slurry to classifiers often remain the weakest link. A single failure in the […]
1. Introduction Tennessee’s wastewater infrastructure landscape is currently undergoing its most significant transformation in decades, driven by rapid population growth in the Nashville-Murfreesboro corridor and massive consent decree-driven overhauls in Memphis, Chattanooga, and Nashville. The state operates under the regulatory oversight of the Tennessee Department of Environment and Conservation (TDEC), managing a network of over […]
Aqua Aerobic Systems: Optimizing Biological Treatment Processes Mechanisms of Aqua Aerobic Systems Aqua aerobic systems are the unsung heroes of wastewater treatment, using a clever blend of biology and engineering to tackle the messiest of municipal challenges. Did you know that these systems can reduce organic matter by up to 90%? That's not just impressive; […]
Solidification of PFAS Waste: An In-Depth Analysis for Environmental Engineers Introduction As the awareness of per- and polyfluoroalkyl substances (PFAS) continues to rise, so does the urgency for effective waste management solutions. Known as "forever chemicals" due to their persistent nature in the environment, PFAS compounds present significant challenges for environmental professionals tasked with waste […]
