Introduction One of the most persistent inefficiencies in modern wastewater treatment plants is the misapplication of mixing energy. While aeration systems typically consume the lion’s share of plant power, submersible mixers often operate continuously in anoxic zones, sludge holding tanks, and equalization basins, accumulating massive lifecycle costs. A surprising industry statistic suggests that up to […]
Introduction For municipal and industrial treatment plant engineers, solids handling frequently represents the single largest operational cost center, often accounting for 40% to 50% of total plant O&M budgets. While liquid stream processes often garner the most design attention, the failure to properly specify dewatering equipment creates a bottleneck that can jeopardize regulatory compliance […]
Introduction For municipal engineers and utility directors, the proliferation of “flushable” wipes and increasing solids loading in wastewater streams has transformed the specification of pump stations. The days of standard solids-handling pumps working universally are over; difficult terrain and high-head requirements often necessitate Low Pressure Sewer (LPS) systems driven by robust grinder pumps. However, selecting […]
Introduction One of the most precarious scenarios for any municipal wastewater utility is the flooding of a dry pit pump station. In traditional designs utilizing standard TEFC (Totally Enclosed Fan Cooled) motors, a line break or seal failure that floods the dry well usually results in catastrophic motor failure, lengthy downtime, and expensive rewind or […]
Introduction In the hierarchy of municipal and industrial fluid control, the ball valve occupies a critical position defined by its low head loss characteristics, tight shutoff capabilities, and versatility across a wide range of diameters. For consulting engineers, plant superintendents, and utility decision-makers, the selection of Original Equipment Manufacturers (OEMs) for ball valves is not […]
Introduction The vertical turbine pump (VTP) serves as a cornerstone of fluid movement in municipal water and wastewater infrastructure. Unlike horizontal pumps, which require significant floor space and rely on positive suction head often provided by gravity or booster systems, vertical turbine pumps are designed to operate submerged, utilizing the fluid source itself to provide […]
1. INTRODUCTION In the architecture of municipal and industrial water and wastewater treatment, chemical feed and storage systems function as the critical control points for process efficacy and regulatory compliance. Unlike passive infrastructure, these systems are dynamic, requiring precise manipulation of fluid chemistry to achieve coagulation, flocculation, disinfection, pH adjustment, and odor control. […]
Certified PFAS Removal Products: An Expert Guide for Water Treatment Solutions Introduction Per- and polyfluoroalkyl substances (PFAS), commonly referred to as "forever chemicals," have emerged as a critical environmental issue due to their persistent presence in water systems and associated health risks. As of July 2025, regulatory frameworks and technological advancements in PFAS remediation are […]
Managing PFAS Investigation Derived Waste: Comprehensive Strategies for Environmental Engineers PFAS (Per- and Polyfluoroalkyl Substances) have emerged as a significant environmental and public health concern over the past two decades. As regulatory scrutiny ramps up and public awareness grows, the management of Investigation Derived Waste (IDW) generated during PFAS assessments has become a pressing issue […]
Treating Comingled Plumes: Challenges and Solutions in Groundwater Remediation Introduction As industrial activities continue to expand, groundwater contamination has become an increasing concern for environmental engineers and regulatory agencies. One of the most significant challenges is the presence of comingled plumes—contaminated zones in groundwater that contain multiple types of pollutants from various sources. This situation […]
