Environmental Pollution Control Laboratory

Presentation

Appropriate equipment to realize all kinds of chemical analyses and microbiological determinations that since 1986 have allowed it to function as an auxiliary Laboratory of the Catalan Water Agency. It also has pilot plants for biological or physicochemical depuration.

Analysis in general

Validation of cations by atomic absorption. Anions evaluation. Fats and oils. Organic and total carbonic. Acidity/alkalinity. Ammoniac and total nitrogen. Phosphorus, nitrites and nitrates, sulphides, etc.

Industrial water

Colour. Conductivity. Dry residue and suspended solids, turbidity. Hardness. Dissolved oxygen. Pathogenic microorganisms. Presence of the most frequent pollutants, TA and TAC, chlorides and sulphates.

Residual waters

DBO and DQO. Decanted volume of sludge. Inhibitory substances, MES, conductivity. Organic metal components. Total microorganisms: fungi, streptococcus, clostridia, coliforms.
Pollution produced in a textile process.
Residual waters depuration. Physicochemical processes, neutralization, decantation, filtration, absorption (active coal or resins)
Oxidation processes.
Biological depurations: Anaerobic and aerobic processes. Selection of specific microorganisms. Activated sludge. Percolating filters. O2 consumption rate.
Conduction of depurations stations. Planning. Test in pilot plant. Inhibitor effect of some effluents. Recycling of effluents once treated.
