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 […]

Belt Press vs Centrifuge: Choosing the Best Sludge Dewatering Solution When choosing how to cut sludge volumes and disposal costs, the belt press vs centrifuge sludge dewatering decision is one wastewater manager faces every day. This post compares belt press dewatering and centrifuge dewatering on performance, energy and operational costs, maintenance and footprint, and environmental […]

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 […]

Ultrafiltration vs Microfiltration: Which Membrane Is Best for Water Reuse? Choosing between ultrafiltration vs microfiltration for reuse shapes pathogen removal, fouling behavior, and total cost of ownership for any reuse project. This article gives municipal and industrial engineers a practical, evidence-based comparison of membrane performance, operational tradeoffs, pretreatment needs, and implications for downstream RO and […]

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 […]
