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
