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, […]

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 […]

No salt water softening systems are increasingly considered where chloride discharge limits, brine disposal costs, or membrane and heat-exchanger fouling make conventional ion exchange impractical. This article evaluates the principal no-salt approaches by mechanism and field performance — template assisted crystallization, electromagnetic and electronic descalers, antiscalant dosing, and membrane alternatives — and compares them to […]

When municipal utilities and plant engineers must deliver reliable permeate at predictable lifecycle cost, selecting from the best ro systems is a technical decision, not a vendor marketing exercise. This buyers guide turns project goals into measurable specs – capacity, flux, recovery, energy use and concentrate handling – shows a reproducible CAPEX and OPEX model, […]

For utility managers and plant engineers deciding between membrane and thermal solutions, a practical answer to what is distillation water and when to specify it matters more than textbook chemistry. This article defines distilled water in operational terms, compares single effect, multi effect and MVR distillation at plant scale, explains what contaminants are removed or […]

For municipal engineers sizing and specifying treatment trains, a ceramics water filter often looks attractive on paper but behaves differently in full-scale service. This article distills field-proven performance ranges, fouling behavior, maintenance and CIP protocols, and lifecycle cost tradeoffs so you can decide where ceramics belong in a multi-stage train. You will find numerical flux […]

Rising tides and salt-laden groundwater are changing the rules for infrastructure in South Florida, turning predictable wear into accelerated asset failure. This article gives municipalities, engineers, and equipment manufacturers a vendor neutral, technically rigorous playbook for identifying coastal stressors affecting miami sewer water assets, diagnosing corrosion mechanisms, and prioritizing adaptation measures with real examples and […]
