2. Lab tests
Trevi has a well-equipped laboratory for analysis and lab-scale experiments to support its consultancy and development of new waste water treatment technologies.
Testing
• COD, BOD, suspended solids
• nitrogen parameters (ammonia, nitrate, nitrite, total nitrogen)
• total Phosphorus
• dry matter, VSS, etc.
• and much more
Microscopic investigation of activated sludge
GC gas analysis
Several lab types and tests 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
