How Does a Screw Press Work? 2026 Sludge Dewatering Guide
A screw press dewaters sludge by rotating a helical screw inside a screened barrel so free water drains and cake compresses across four pressure zones. Feed typically enters at 0.5–3% DS; mixed biological sludge often leaves at 18–25% DS when polymer dose and back-pressure are set correctly. Key controls are screw speed (1–5 rpm), screen aperture, discharge-cone back-pressure, and 5–15 kg active polymer per tonne DS. Volute units suit variable municipal loads; continuous units suit steadier industrial feeds.
How an Anaerobic Digester Works: 2026 Engineering Guide
An anaerobic digester works as a sealed, oxygen-free reactor that converts organic wastewater into biogas (typically 50–75% methane) and nutrient-rich digestate.

How Does a UASB Reactor Work? Process, Design & 2026 Guide
A UASB (Upflow Anaerobic Sludge Blanket) reactor treats high-strength wastewater by passing it upward through granular anaerobic sludge at 0.5–1.5 m/h. Bacteria convert 80–95% of COD into 65–75% methane biogas at loading rates of 4–15 kg COD/m³/day, and the three-phase separator retains biomass in place of a secondary clarifier. Design uses HRT 12–24 h and mesophilic 30–37°C. Nitrogen and phosphorus removal stay under 15%, so downstream polishing carries permit compliance.

How Does an Oxidation Ditch Work? Process, Design & 2026 Performance
An oxidation ditch is a racetrack activated-sludge basin that circulates mixed liquor at 0.25–0.35 m/s while forming aerobic and anoxic zones in one loop. Basin volume is set by SRT—typically 12–24 days for nitrification—with HRT of 6–30 h and MLSS of 1,500–5,000 mg/L. MLE anoxic recycle at 3Q–4Q raises TN removal when the in-channel anoxic fraction is not enough.
AAO Wastewater Treatment Process Engineering Guide: 2026
The AAO process removes carbon, nitrogen, and phosphorus by passing one sludge line through an anaerobic selector (DO below 0.1 mg/L), an anoxic basin (DO below 0.2 mg/L), and an oxic tank (DO 1.5-2.5 mg/L), with internal recycle at 200-400% of influent flow returning nitrate for denitrification. A tuned municipal train delivers TN below 15 mg/L and TP below 1 mg/L without chemical precipitation. Winter nitrification drives SRT to 20-25 days when mixed-liquor temperature falls below 15 C.
