How to size a laboratory wastewater treatment system

Choosing a treatment system starts with how much effluent your analyzers produce and how it is spread over the day.

Step 1: list your analyzers

Note each analyzer’s make, model and type (chemistry, immunoassay, hematology, flow cytometry) and the hours it runs per day.

Step 2: estimate daily volumes

Maumee estimates daily waste for 8 hours of operation, split into concentrated and non-concentrated effluent. As a guide from its analyzer survey: flow cytometers produce around 25–55 L, hematology analyzers around 45–110 L, and chemistry or integrated chemistry–immunoassay platforms from around 85 L up to more than 400 L.

Step 3: work out the design flow

Maumee calculates a design flow as the full-use hourly average reduced by 30% to allow for idle and standby time. For example, an analyzer producing 160–200 L in 8 hours has a full-use average of 20–25 L/h and a design flow of about 13–14 L/h.

Step 4: compare with system capacities

  • TRESA H: 12 L/h, up to 2 hematology analyzers
  • TRESA CI: 60 L/h, up to 2 chemistry / immunoassay analyzers
  • TRESA CIH: 120 L/h, up to 3 analyzers
  • TRESA CRD: 1 Roche biochemistry analyzer
  • TRESA TL: up to 1,500 L per day for the whole laboratory
