2. Lab tests

Trevi has a well-equipped laboratory for analysis and lab-scale experiments to support its consultancy and development of new treatment technologies.

Waste water

Various parameters can be analysed:

  • COD, BOD, suspended solids

  • nitrogen parameters (ammonia, nitrate, nitrite, total nitrogen)

  • total Phosphorus

  • dry matter, VSS, etc.

  • Microscopic investigation of activated sludge

  • GC gas analysis

Several setups and tests are possible:

  • jar-test or flocculator (physico-chemical treatment simulation)

  • Buchner-funnel test (standardised sludge dewatering capacity test)

  • Zahn-Wellens test (standardised biodegradability test)

  • toxicity testing

  • evaporation testing

  • respiration testing (standardised test to determine endogenous and exogeneous sludge activity)

  • determining activated sludge nitrification rates

Gas abatement

All kinds of gas abatement techniques can be tested:

  • Lab scale

    • Several biofiltration setups

    • Gas scrubber

    • Dry sorbent filter

    • Batch reactor tests

    • Bubble column experiments

  • GC gas analysis

    • Online monitoring during lab scale testing

    • Follow-up of existing full-scale installations

    • Headspace analysis
