Biological Aerated Filter Design: 2026 Engineering Guide to BAF Process, Media & Sizing
Biological aerated filter design covers submerged packed-bed reactors that oxidise BOD, nitrify ammonia, and capture solids in one vessel. Typical industrial envelopes use 2–6 mm media, hydraulic loading of 4–10 m/h, EBCT of 20–60 minutes, and backwash every 24–72 hours. Media class, pretreatment for TSS and FOG, and backwash air/water rates decide whether effluent COD and NH₃-N targets are met without a secondary clarifier.

Delhi DJB sewage plant tender under corruption probe; Tiruchi 100 MLD STP nears completion
On 2026-08-18, Delhi's Anti-Corruption Branch arrested six people in a case over Delhi Jal Board sewage treatment plant upgrade tenders covering 10 plants and roughly Rs 1,943 crore in contract value, with the matter produced before a Special Judge the following day. Separately, Tiruchi Corporation's 100 MLD (100,000 m³/day) sewage treatment plant at Panjapur is progressing and is expected to be completed by August, even as other Corporation projects — UGD Phase IV, road and drain works — remain slow pending fund release. For operators, the two stories together frame a working week of large municipal STP upgrades: one disrupted by a corruption investigation into how the technical specification was written, one pressing through to mechanical completion into a still-incomplete drainage catchment.
