Greywater Recycling: Sustainable Water Reuse Solutions Greywater recycling systems provide a practical route to cut potable water use and reduce sewer loads in municipal and large-building projects. This article delivers the engineering, regulatory, and lifecycle guidance needed to scope, specify, and operate nonpotable greywater reuse at scale, with performance targets, instrumentation and monitoring requirements, and […]
Introduction One of the most insidious threats to the longevity of large-scale pumping systems is the phenomenon of air entrainment caused by intake vortices. For municipal and industrial engineers, the challenge is compounded when geotechnical constraints force the use of deep, circular containment structures. Diaphragm Wet Well Design and Minimum Submergence to Prevent Vortexing is […]

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 […]
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 […]
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, […]
Introduction One of the most persistent challenges in municipal and industrial water treatment design is the accurate measurement of fluid velocity and volumetric flow under varying hydraulic conditions. Engineers often default to legacy specifications without re-evaluating the underlying technology, leading to significant lifecycle cost discrepancies. A surprising industry statistic suggests that up to 30% of […]
UV Water Disinfection: A Proven Method for Safe Drinking Water Ultraviolet water disinfection uses germicidal UV-C to inactivate bacteria, viruses, and protozoa without introducing chemical residuals. This article gives municipal decision makers, plant designers, and operators the technical guidance they need: dose metrics in mJ/cm2 and log reductions, reactor hydraulics and UVT limits, lamp and […]
