TRESA TL

On-site advanced oxidation (ozone + UV-C) for laboratory-wide effluent

TRESA TL is the on-site solution designed to help healthcare laboratories meet the most stringent requirements for effluent treatment. Its advanced oxidation process (AOP) combines ozone with UV-C light to neutralize and inactivate pathogens and microorganisms, reduce chemicals and COD, and improve the biodegradability of effluent before it reaches the treatment plant. It treats up to 1,500 L of laboratory wastewater per day.

  • Neutralization and inactivation of pathogens and microorganisms
  • Reducing chemicals and the COD level of the effluent
  • Improving biodegradability of effluent before the treatment plant

Designed for

  • Clinical and hospital laboratories, including biochemistry, hematology, microbiology and histopathology
  • Research laboratories
  • Specialty test laboratories: food, agriculture, blood banks and anti-doping
  • Laboratories producing up to 1,500 L of wastewater per day

Key features

  • Advanced oxidation process combining ozone (O₃) and UV-C
  • Two tanks: primary tank and reaction tank, with venturi ozone injection
  • Closed-loop circulation through the UV-C lamps; excess ozone pre-treats the next cycle
  • Active-carbon filter captures residual dissolved ozone before discharge
  • Fully automated process with real-time monitoring and efficiency control through PLC
  • No harsh chemicals
  • Low consumables and maintenance requirements
  • Avoids on-site storage and transport of untreated biohazardous waste
  • Remote alarm system

Treatment process

Advanced oxidation process (AOP). Ozone combined with UV-C generates hydroxyl radicals to oxidize organic contaminants and reduce COD.

  1. Fill and start

    Effluent collects in the primary tank. Once it is full, the cycle starts and the ozone generator switches on.

  2. Ozone injection

    The reaction-tank pump pushes the wastewater into the reaction tank together with ozone, through a venturi cone that helps the ozone dissolve.

  3. Closed-loop AOP

    With the reaction tank full, the switch valve closes and the effluent circulates in a closed loop between the reaction tank and the UV-C lamps while ozone is continuously injected. Excess ozone returns to the primary tank to pre-treat the next cycle.

  4. Ozone removal

    When the set cycle time is reached (it sets the ozone quantity and UV-C dose), circulation stops and the effluent passes through an active-carbon filter that captures residual dissolved ozone.

  5. Discharge

    The treated effluent is discharged to the main sewer, subject to local requirements, and the next cycle starts.

Principle of the advanced oxidation process

The advanced oxidation process used by TRESA TL combines ozone (O₃) with UV-C light, giving a highly effective treatment through three distinct reactions.

  1. Ozone breakdown with UV-C light

    UV-C light breaks ozone down into oxygen molecules and highly reactive oxygen atoms, which attack and break down pollutants.

    Reaction: O₃ + UV-C → O₂ + O

  2. Creation of hydroxyl radicals (•OH)

    The reactive oxygen atoms interact with water molecules to form hydroxyl radicals, among the most effective agents for breaking down organic contaminants.

    Reaction: O + H₂O → 2 •OH

  3. Direct ozone oxidation

    Ozone also oxidizes contaminants directly, breaking harmful compounds down into safer by-products. UV-C light improves the efficiency of this step.

    Reaction: O₃ + contaminant → O₂ + breakdown products

Compounds that can be oxidized

Organic compounds react with ozone in a process similar to combustion, with carbon dioxide and water as the main end products. Inorganic compounds of lower oxidation numbers react with ozone to produce oxides, although many inorganic compounds do not react. Examples of compounds that can be oxidized:

Acids, alcohols, aldehydes and ketonesAcetic acid, acetone, n-butyl acetate, butoxyethanol, cetyl alcohol, formaldehyde, isopropyl alcohol, glycerol, methacrylic acid, methyl ethyl ketone (MEK), propylene glycol
Aromatic compoundsBenzene, benzyl alcohol, n-butyl phthalate, camphor, para-phenylenediamine, resorcinol, styrene, tricresyl, toluene, xylene
Aliphatic compoundsButane, isobutane, liquefied petroleum gas (LPG), mineral spirits, propane
ChloridesMethylene chloride, chloroform, methyl chloroform, perchloroethylene, trichloroethylene, phenacetin
Nitrogen-containing compoundsHydrogen cyanide, aminophenol, ammonia, ammonium hydroxide, benzopyrene, EDTA (ethylenediaminetetraacetic acid), ethanolamine
Sulfur-containing compoundsAmmonium persulfate, ammonium thioglycolate, sodium bisulfite, thioglycolic acid

Wastewater tests are performed before and after installation of the TRESA TL to verify the results of the AOP process on organic and inorganic compounds.

TRESA TL questions

How much wastewater can TRESA TL treat?

Up to 1,500 L per day, the effluent of a whole laboratory.

How does TRESA TL work?

It uses an advanced oxidation process: ozone combined with UV-C generates hydroxyl radicals that break down organic contaminants and reduce COD, while also inactivating microorganisms.

What room does TRESA TL need?

A closed space with ventilation of at least 10 m², a 230 V supply and access to the main sewer. City water is optional.

How are results verified?

Wastewater tests are performed before and after installation to verify the results of the oxidation process on organic and inorganic compounds.
