Dairy ETP monitoring, from effluent inflow to treated discharge
Dairy ETP monitoring measures effluent inflow, load, treatment performance and discharge continuously instead of by daily grab sample. Aqueduct reads flow, pH, temperature, dissolved oxygen and BOD or COD from online analyzers or lab results, links load spikes to the CIP cycle or product loss upstream, tracks sludge, and keeps a continuous evidence record for your team to report to the regulator.
Why the ETP is where dairy losses surface last
Load spikes with no source
A COD spike arrives at the equalization tank, and nobody can say whether it came from a CIP dump, a spill or a product changeover.
Grab samples, not a record
Daily lab samples show a point in time. The hours between samples are where shock loads and bypass risks sit.
Aeration running blind
Blowers run at fixed speed whatever the load, which wastes power at night and starves the biology at peak.
Evidence gathered at deadline
Consent and disclosure reports are compiled from logbooks when the request arrives, not drawn from a continuous record.
What Aqueduct measures across a dairy ETP
| Stage | Measured | What Aqueduct derives |
|---|---|---|
| Inflow and equalization | Flow, pH, temperature, tank level | Hydraulic and organic load by hour, linked to upstream events |
| Fat removal and DAF | Flow, chemical dosing, float removal | Dosing per unit of flow and fat recovered |
| Biological treatment | Dissolved oxygen, blower kW, MLSS where measured | Aeration energy per unit of load and DO held against target |
| Clarifier and sludge | Sludge volume, dewatering run hours, cake weight where recorded | Sludge produced per unit of load treated |

Common questions
It lines up ETP inflow load with CIP cycles, changeovers and line events from plant SCADA. When a spike follows a specific circuit or event, the ticket names it and goes to the process team that owns it.
No. Aqueduct supplies a continuous measured record of inflow, treatment and discharge, with deviations and their closure. Your team or your environmental consultant reports to the regulator and certifies compliance.
Aqueduct baselines blower energy against organic load and dissolved oxygen, and flags hours where aeration runs well above what the load needs. Where control is enabled, with owner approval, blower schedules can be adjusted, with every command logged.
Yes, from online analyzers where fitted or from lab results entered against the sample time. Aqueduct lines those values up with hourly inflow, so load is calculated as mass rather than concentration alone, and a heavy hour can be traced upstream. See BOD and COD.
