Chlorine Disinfection for Water Treatment: Safety and Effectiveness Chlorine disinfection water remains the workhorse for municipal drinking and wastewater systems because it delivers rapid inactivation of many pathogens and a persistent distribution residual. This article gives engineers and operators practical, implementation-focused guidance on how chlorine inactivates organisms, CT calculations with worked examples, dosing and contact […]
Introduction In municipal wastewater treatment and industrial sludge handling, the premature failure of progressive cavity (PC) pump stators remains one of the most persistent and costly maintenance burdens. Engineers frequently specify robust hydraulic conditions, yet the interface between the pump mechanics and the electrical control system is often where reliability disintegrates. A startling volume of […]
FACILITY BASIC INFORMATION Plant Name: Tomahawk Creek Wastewater Treatment Facility (TCWWTF) Location: Leawood, Kansas (Serving Overland Park and Johnson County) Operating Authority: Johnson County Wastewater (JCW) Design Capacity: 19 MGD (Average Daily Flow) / 172 MGD (Peak Wet Weather) Current Average Flow: ~10-12 MGD Population Served: Approx. 150,000 residents Service Area: Overland Park, Leawood, Prairie […]
Biosolids Management: Best Practices for Treatment Plants Biosolids management is where regulatory pressure, operational cost, and community risk collide—get the decisions right and you control disposal costs and recover resources; get them wrong and you face fines, complaints, and rising hauling bills. This practical guide gives treatment plant operators and engineers a technical roadmap for […]
INTRODUCTION One of the most persistent causes of premature equipment failure in municipal and industrial fluid handling systems is the disconnect between the design point and the actual operating reality. Engineers frequently specify pumps for a peak flow condition that occurs less than 5% of the time, leaving operators to manage equipment that runs inefficiently—and […]
Location: Villa Hills, Kentucky | Operator: Sanitation District No. 1 (SD1) | Capacity: 46.5 MGD FACILITY BASIC INFORMATION Plant Name: Dry Creek Wastewater Treatment Plant Location: 1045 Eaton Drive, Villa Hills, KY 41017 Operating Authority: Sanitation District No. 1 of Northern Kentucky (SD1) Design Capacity: 46.5 MGD (Average Daily Flow) Peak Hydraulic Capacity: ~100+ MGD […]
Introduction to Intake Hydraulics For municipal and industrial engineers, the physical geometry of a pump station is often treated as secondary to the selection of the pump itself. However, industry data suggests that nearly 30% of premature pump failures—manifesting as vibration, cavitation damage, and bearing wear—are directly attributable to poor intake conditions rather than mechanical […]
Coagulation and Flocculation: Essential Steps in Water Purification Coagulation flocculation water treatment is the frontline process that decides whether downstream filtration, membranes and disinfection will meet turbidity and DBP precursor targets. This article turns coagulation chemistry into practical decisions—coagulant and polymer selection, rapid mix and flocculation G and time ranges, jar testing and pilot methods, […]
The authoritative technical resource for the East Bank facility’s operations, infrastructure, and engineering specifications. FACILITY BASIC INFORMATION Plant Name: East Bank Wastewater Treatment Plant Location: 6000 Russell Street, River Ridge, Jefferson Parish, Louisiana 70123 Operating Authority: Jefferson Parish Department of Sewerage Design Capacity: 36.0 MGD (Average Daily Flow) / 80.0+ MGD (Peak Hydraulic) Current Average […]
Wastewater Aeration Systems: Improving Treatment Efficiency Aeration system wastewater installations typically consume 45 to 60 percent of a municipal treatment plant energy budget and determine whether biological processes meet effluent nitrogen and BOD targets. This guide gives plant managers, process engineers, and operators a practical roadmap for selecting, designing, operating, retrofitting, and maintaining aeration system […]
