Wastewater Design: overflow_rate_secondary_peak to tn_removal_trickling_filter
Wastewater and leachate treatment design criteria — process design parameters (HRT, SRT, MLSS, F/M, loading rates, membrane flux) and removal efficiencies (BOD, TSS, TN, TP) for activated sludge, SBR, MBR, oxidation ditch, trickling filter, aerated lagoon, and facultative lagoon processes, covering both municipal wastewater and landfill leachate applications
| parameter id | category | design basis | notes | parameter name | subcategory | unit | value max | value min | value typical |
|---|---|---|---|---|---|---|---|---|---|
| overflow_rate_secondary_peak | secondary_clarifier | WEF MOP 8 | At peak hourly flow | Secondary clarifier overflow rate (peak) | hydraulic | gpd/ft2 | 1,600 | 1,000 | 1,200 |
| solids_content_was | sludge | Metcalf & Eddy 5th Ed Table 14-3 | As withdrawn from secondary clarifier | Solids content of WAS | biological | % | 1.5 | 0.5 | 0.8 |
| srt_oxidation_ditch_leachate | process_design_leachate | Extended aeration principles | Longer SRT for biomass acclimatization to leachate toxicity and refractory compounds. | Solids retention time - Oxidation ditch treating leachate | oxidation_ditch | days | 50 | 25 | 35 |
