Oxidation Ditch Retrofit and Upgrade: 2026 Engineering Guide
Oxidation ditch retrofit upgrade work starts by naming the binding constraint: DO collapse, clarifier TSS, or SRT limits. EPA 832-F-00-013 still sets the design envelope for SRT, MLSS, velocity, and oxygen demand. Pathway choices are supplemental aeration (20–40% of greenfield), full fine-bubble conversion (40–60%), or an MLE add-on for TN below 5 mg/L.
Oxidation Ditch Commissioning Engineering Guide: 2026
Oxidation ditch commissioning runs from civil handover through clean-water velocity verification, seeding, a 28-day biological ramp, and a 7-day composite acceptance test. Hold channel velocity at 0.25–0.35 m/s before seeding, start MLSS at 2,000–3,000 mg/L, and lock SRT at 20–24 days to favor nitrifier colonization. EPA reference plants reach 96-99% BOD removal and about 90-94% total nitrogen removal.

Primary Clarifier Scum Overflow Troubleshooting Guide: 2026
Clarifier scum is the floating mat of FOG, trash, and biological foam that collects in the top 50-300 mm of a clarifier and overflows the scum trough when capture fails. Diagnosis splits into three visual types - greasy FOG mat, stable filamentous foam, and denitrification float - each with a distinct fix. Mechanical options range from ducking skimmers to full-surface motorized arms, while influent FOG above 200 mg/L justifies a DAF stage achieving 90%+ FOG removal.

How to Solve Sludge Foaming in 2026: Causes, Diagnosis & Control
Sludge foaming in activated-sludge and MBR plants is driven by filamentous biosurfactants, FOG, or chemical detergents. Biological foam is tan to brown and stable for hours; chemical foam is white and collapses in minutes. High SRT, low F:M, DO below 1.5–2.0 mg/L, and FOG above 50–100 mg/L raise risk when two or more coincide. Confirm foam type with visual, microscopy, parameter, and antifoam-tracer checks before changing wasting or dosing.
