Phosphorus Removal Technologies: From Chemical Precipitation to Enhanced Biological Options Facing stricter permits and tighter budgets, municipal utilities must choose between several phosphorus removal technologies for wastewater that differ in footprint, cost, sludge impact, and resilience to load and temperature swings. This article compares chemical options such as alum and ferric salts, tertiary solids separation, […]

Dissolved Air Flotation: Optimizing Solids Removal in Primary and Tertiary Treatment Dissolved air flotation for solids removal is the practical choice when clarifiers struggle with low-density, hydrophobic, or algal solids, but only when the system is designed and tuned correctly. This how-to guide gives municipal decision makers, design engineers, and plant operators a field-tested roadmap […]

Energy Efficiency Upgrades for WWTPs: Low-Cost Measures with Big Savings Rising energy costs and shrinking municipal budgets mean wastewater treatment plant energy efficiency upgrades are no longer optional; they are the fastest way to reduce operating costs without major process overhauls. This practical guide walks municipal decision makers, operators, and engineers through low-cost, low-risk measures—targeting […]

Membrane Cleaning Strategies: Extend Life and Reduce Downtime of Filtration Systems Membrane cleaning strategies for wastewater membranes that are vague or generic cost plants time and money; this guide gives operators and engineers practical, chemistry-specific tactics to cut unplanned downtime and extend membrane life. You will learn how to identify dominant foulants, set monitoring and […]

Nitrification Optimization Strategies: Improving Stability and Effluent Quality Stable nitrification is often the difference between consistent permit compliance and repeated, expensive emergency fixes. This practical guide on nitrification process optimization for wastewater plants gives operators and engineers a prioritized playbook — from sensor QA/QC and monitoring to DO and SRT tuning, IFAS/MBBR retrofits, sidestream treatment, […]

Solids Dewatering Equipment Compared: Belt Presses, Centrifuges, and Screw Presses Choosing the right dewatering machine can make or break sludge handling costs and compliance; this solids dewatering equipment comparison cuts through vendor claims to show how belt presses, decanter centrifuges, and screw presses actually perform in the field. You will get practical, metric-driven guidance on […]

Membrane Filtration for Wastewater Reuse: Selecting the Right System for Your City When cities must stretch water supplies and meet tougher reuse rules, membrane filtration for wastewater reuse is a practical path, but choosing the right system is where projects stall. This guide gives municipal engineers and plant managers an engineering-first decision framework that links […]

Estimating the Cost of PFAS Removal Systems: Capital, O&M, and Lifecycle Factors Estimating the cost of pfas removal systems is rarely straightforward; influent concentrations, treatment goals, site footprint, and disposal pathways produce wide swings in capital and O&M demands. This guide gives municipal engineers and owners a repeatable framework to turn influent data into equipment […]

Ion Exchange for PFAS: Design Considerations and Operational Tips When regulatory limits fall into the low parts-per-trillion range, ion exchange pfas removal is often the pragmatic choice for municipal systems and remediation sites. This guide gives engineers and operators the design and operational detail they need — resin selection, pretreatment, pilot testing, sizing calculations, regeneration […]

Municipal utilities face a narrow window to set credible PFAS monitoring before steady regulation and public scrutiny force expensive retrofits; this practical guide to pfas testing methods for municipalities focuses on what to specify in contracts, how to prevent field and lab contamination, and how to turn data into treatment decisions. It compares targeted LC-MS/MS […]
