Field guide: Effluent Discharge Logger
An effluent treatment plant is judged at one pipe, by a handful of numbers — and the operator's daily log of those numbers is both the early-warning system and the legal record. This logger encodes India's general discharge standards for inland surface water (pH 5.5–9.0, BOD ≤30, COD ≤250, TSS ≤100 mg/L) as instant flags; your consent-to-operate may set stricter values, and the note field is where consent-specific limits live alongside.
The trends panel is the operations tool: BOD creeping toward the limit over two weeks is a bug in the biology (loading, aeration, bulking) announcing itself while there's still time; the COD:BOD ratio drifting up suggests the influent is changing character. Exceedances logged honestly, with corrective notes, read very differently to a regulator than gaps in the record — environmental enforcement treats missing data as the worst data.
Field tips
- Sample at the same point and hour daily — composite where your consent requires it; grab-sample timing games fool nobody and break trends.
- Watch the COD:BOD ratio (~2–2.5 for sewage-like effluent): a climb means less-biodegradable load arriving — upstream process change hunting time.
- Log flow with every sample; concentration limits paired with consented quantity is what mass-load compliance is computed from.

Frequently asked questions
What's the difference between BOD and COD?+
BOD measures oxygen consumed by microbes degrading the organics (the biological, days-long test); COD measures chemically oxidizable matter (hours). COD ≥ BOD always. The ratio is diagnostic: ~2 means biodegradable (sewage-like), >4 means refractory chemicals your biological plant can't fully treat — and the receiving stream inherits.
Do these limits apply to my facility?+
The encoded values are India's general standards for discharge to inland surface waters — the default baseline. Your consent may be stricter (sensitive receiving waters) or different (sewer discharge to a CETP/STP has its own, usually laxer, limits since downstream treatment follows). The consent document always wins; log its limits in your site notes.
What should happen when a reading exceeds limits?+
Operationally: verify (re-sample), diagnose (the trend usually shows the slide began days earlier), correct, and document each step in the reading's note. Legally: many consents require reporting exceedances within set windows. An exceedance with a documented response is an incident; a hidden one found by a surprise sample is a case.
Can field meters replace lab analysis here?+
pH and flow, yes — that's standard daily operator data. BOD/COD/TSS need lab methods (BOD is literally a 3-day incubation); field COD kits exist for screening. The working pattern this log supports: daily field parameters + periodic lab results entered when they arrive, one continuous record per outfall.
