INTRODUCTION In the design and operation of municipal and industrial wastewater treatment plants, few components cause more disproportionate downtime relative to their cost than isolation valves. A seized gate valve in a grit chamber or a leaking knife gate in a sludge line can force partial plant shutdowns, bypass pumping scenarios, and significant unplanned maintenance […]

MLE Process for Wastewater Treatment: Implementation and Benefits Understanding the MLE Process in Wastewater Treatment When it comes to wastewater treatment, the MLE process isn't just a fancy acronym; it's a game-changer for municipalities looking to enhance their treatment capabilities. Picture this: a city with a population of 100,000 generates about 10 million gallons of […]

Advanced Odor Control Strategies for Wastewater Treatment Facilities Chemical Odor Control Techniques When it comes to odor control for wastewater, the stakes are high. A single whiff of that unmistakable scent can lead to complaints, lost business, and even fines. In fact, studies show that nearly 60% of residents near wastewater facilities report issues related […]

1. Introduction In the hierarchy of fluid handling equipment within municipal and industrial sectors, dewatering pumps occupy a unique and critical position. Unlike permanently installed process pumps designed for steady-state operations within a treatment plant, dewatering pumps are often tasked with transient, emergency, or variable-duty cycles in uncontrolled environments. For the consulting engineer and plant […]

1. Introduction In the water and wastewater (W/WW) utility sector, Supervisory Control and Data Acquisition (SCADA) systems and Human-Machine Interfaces (HMI) serve as the central nervous system of critical infrastructure. Unlike discrete manufacturing, where operations are often contained within a single building, water utilities manage geographically dispersed assets ranging from remote lift stations and booster […]

Introduction In municipal water and wastewater treatment infrastructure, valves act as the critical control points for hydraulic stability, process isolation, and flow regulation. A surprising statistic in utility asset management reveals that while valves often constitute less than 10% of a plant’s capital cost, they account for upwards of 25% of the maintenance budget over […]

1. Introduction to Disinfection Systems in Water and Wastewater Treatment Disinfection remains the most critical unit process in the protection of public health within municipal and industrial water cycles. In potable water treatment, disinfection serves as the primary barrier against waterborne pathogens, ensuring the inactivation of bacteria, viruses, and protozoa before distribution. In wastewater treatment, […]

Introduction In municipal and industrial water and wastewater systems, the control valve serves as the primary mechanism for hydraulic regulation. Unlike isolation valves, which are designed for infrequent open/close cycles, control valves must dynamically modulate flow and pressure to maintain system stability, protect aging infrastructure, and ensure consistent delivery of potable water or efficient processing […]

Introduction In the realm of municipal and industrial wastewater management, the failure of a grinder pump due to ragging or jamming is rarely a minor inconvenience—it is a distinct operational hazard that leads to Sanitary Sewer Overflows (SSOs), costly emergency call-outs, and accelerated equipment degradation. With the increasing prevalence of “non-flushable” wipes and high-tensile synthetic […]

1. Introduction Biogas systems serve as the critical interface between anaerobic digestion processes and energy recovery or disposal mechanisms in municipal and industrial wastewater treatment facilities. While historically viewed merely as a waste byproduct requiring safe disposal, biogas—comprising primarily methane (CH4) and carbon dioxide (CO2)—is now universally recognized as a valuable renewable energy resource. The […]
