Monitoring Micropollutants for Reuse: Practical Strategies for Compliance and Safety Successful wastewater reuse depends on knowing what remains at trace levels, which is why practical micropollutant monitoring strategies for wastewater reuse must be tied to operational decisions, not academic curiosity. This guide takes municipal decision makers, design engineers, and plant operators through prioritized compound lists, […]

Instrumentation & Control Systems for WWTPs: Modernizing for Reliability and Compliance Aging field devices, obsolete PLCs, tighter NPDES windows, and rising cybersecurity risk mean utilities can no longer rely on reactive fixes to keep permits and processes in check. This guide provides a practical, step-by-step framework for wastewater treatment plant instrumentation and control systems upgrades, […]

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 […]

Advanced Oxidation Processes: Tackling Micropollutants in Wastewater Effluent Micropollutants in treated effluent are driving municipalities to add tertiary barriers, and advanced oxidation processes for wastewater are among the most effective but technically demanding options. This practical, evidence-driven guide explains how AOPs work, compares major platforms, lays out design and integration rules, and covers monitoring, byproduct […]

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 […]

Sequencing Batch Reactor Best Practices: Design and Operational Tips for Operators If your plant struggles to hold nitrification, control solids, or keep energy costs down, this hands-on guide lays out sequencing batch reactor design best practices for operators and engineers who need actionable targets, not theory. You will get numeric design criteria (MLSS, SRT, cycle […]

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, […]

Biological Nutrient Removal: Design Guidelines for Reliable Nitrogen & Phosphorus Control Reliable control of nitrogen and phosphorus depends on design choices, sizing, and operational control rather than hopeful tuning after startup. These biological nutrient removal design guidelines translate standards and field-proven practice into clear decision rules, numeric setpoints, control logic, and pilot-testing priorities for engineers […]
