We have a laboratory specialised in carrying out analyses of different characterisation parameters, for periodic monitoring samples and for physico-chemical, respirometric studies and optimisation of chemical product dosage studies.

The laboratory is authorised by the General Directorate of Environmental Quality and Climate Change (DGQACC) of the Government of Catalonia, with the number 098-LA-AIG.

Physico-chemical characterisation of waste and process waters

Analysis of different parameters in order to characterise the sample. Conductivity, pH, MES, DQO, DBO5, chlorides, sulfates, total phosphorus, organic and ammoniacal nitrogen, inhibitory substances, oils and fats, sulphides, metals.

Follow-up analytical controls

Periodic analytical controls of samples of different origins from the wastewater treatment plants and reports on their operation.


Respirometric studies in order to analyse the activity of the mud and the impact of process waters on it.

Microscopic observations

Observations of biological sludge in order to observe the type of microorganisms in the activated sludge.

Coagulation/flocculation studies

Laboratory-scale coagulation/flocculation tests to determine suitable coagulants and flocculants and optimal dosages.

Settling studies

Laboratory-scale tests to improve settling using organic coagulants.
