See how TRESA works
A 49-second introduction to treating laboratory wastewater where it is generated: the problem, the four treatment steps and the TRESA range.
What happens to laboratory wastewater today
Many automated IVD analyzers generate liquid waste containing residual reagents, chemicals and biological material associated with patient samples.
Depending on the laboratory and local requirements, this liquid waste may be collected in containers, stored on site and transported off site for treatment or disposal. Each additional handling step can add cost and operational risk, including the potential for spills and staff exposure.
- Storing it on site
- Moving it around the lab
- Trucking it away
- Paying for disposal
- Staff exposure
Where point-of-use treatment is not installed
Lab effluent flows into tanks outside
It builds up on site, still untreated
A sewage contractor pumps it into a tanker
It is driven off site for treatment
Treated automatically, right where it starts
The wastewater is treated close to the analyzer that generates it, using a treatment configuration selected for the specific application and effluent characteristics.
Collect
Waste runs straight from the analyzer into the unit's built-in tank.
Condition
Depending on the application, the effluent is conditioned by controlled dilution and/or filtration.
Treat
UV-C reactors inactivate microorganisms (CRD, CI, H, CIH), or ozone + UV-C advanced oxidation treats laboratory-wide effluent (TL).
Discharge
Treated effluent goes to an approved drain or sewer, subject to applicable local requirements.
Why treat it where it is produced
Handled in the lab
The wastewater is dealt with on the spot, not sent elsewhere.
No tanks to fill
With direct treatment, nothing waits around for collection.
Fewer trucks
Where permitted and applicable, there may be no need to transport the treated liquid waste off site.
Full visibility
Treatment cycles are automated and monitored by the system, giving operational visibility of the process.
Safer for staff
Staff no longer carry or pour hazardous liquids by hand.
Simpler routine
A clean, predictable way to manage laboratory wastewater.
Lower risk
Less handling and storage of untreated liquid waste helps reduce spill and exposure risks.
Built for compliance
Designed to help laboratories meet the discharge requirements that apply locally.
Find a solution for your application
Start from the analyzers in your laboratory. Final selection depends on analyzer models, effluent volume and local discharge requirements, so our team confirms the right configuration for each site.

Frequently asked questions
What is the TRESA range?
TRESA is a range of five on-site treatment systems for liquid waste from clinical laboratory and IVD analyzers, made by Maumee Technologies in Cincinnati, Ohio. It runs from units for one or two analyzers (TRESA CRD, CI and H) to a multi-analyzer cabinet (TRESA CIH) and a laboratory-wide system (TRESA TL).
Which TRESA system suits my laboratory?
It depends on your analyzer types and models, how many analyzers you run, your daily effluent volume and local discharge requirements. Send us your analyzer list through the contact form and our team will advise which configuration may suit your site.
Where can treated effluent be discharged?
TRESA systems discharge treated effluent to an approved drain or sewer connection. Discharge must comply with the requirements that apply at your site, which should be confirmed before installation.
What utilities do TRESA systems need?
All models use a 230 V supply and a drainage point. TRESA CI and H also need a water supply for controlled dilution; TRESA TL needs a closed, ventilated room of at least 10 m² and, optionally, city water.
Are TRESA systems independently verified?
Yes. The TRESA series has undergone Environmental Technology Verification (ETV) under ISO 14034:2016, verification statement ICAP260006 issued by the International Certification Authority.
How do I get a brochure or datasheet?
Brochures and datasheets are sent on request. Use “Request product information” and choose “Brochure or datasheet” as the request type.
