Description

The Environmental Technology Group offers their 25 years of experience in the physicochemical/biological characterization of waste waters, solid waste and exhaust gases for industries, R&D institutes and public administrations. PHYSICOCHEMICAL ANALYSIS - Total COD and soluble COD (standard and closed back-flow) - BOD5 (standard methods) - soluble TOC (TOC-VCSH Shimadzu analyzer) - TS, VS, TSS y VSS (standard methods) - NH4 + (NH4 + specific sensor and destillation + titulation) - NO3- and NO2- (HPLC-IC) - TKN (standard methods) - TN (TNM-1 Shimadzu analyzer) - total PO43- and soluble PO43 (standard spectrophotometry methods) - SO42- and S2O32- (HPLC-IC)- VOLATILE FATTY ACIDS (HPLC-UV and GC-FID) - PH - ALKALINITY (UNE standards) - CONDUCTIVITY - GREASE AND OIL (Standard methods) - CALIBRATION AND PARTICULE POLLUTION - COLOR (standard methods) - TOXICITY TEST (Respirometric and luminiscent tests) - RESPIROMETRIC TESTS - VOLATILE ORGANIC COMPOUNDS (GC-MS & GC-FID) - PERMANENT GASES - BIOGAS (O2, CO2, CH4, H2S, N2, H2) (GC-TCD) MOLECULAR BIOLOGY ANALYSIS - DYNAMIC MONITORING OF THE MICROBIAN POPULATION IN BIOLOGICAL TREATMENT SYSTEMS PCR -DGGE (POLYMERASE CHAIN REACTION AND DENATURING GEL GRADIENT ELECTROPHORESIS): POPULATION'S STRUCTURE AND DYNAMICS - FISH (IN SITU HYBRIDIZATION FLUORESCENCE) IDENTIFICATION AND QUANTIFICATION OF MICROORGANISMS - MICROSCOPIC ANALYSIS OF ACTIVATED BODAS ESTIMATION OF THE PERFORMANCE OF THE PROCESS.- MONITORING OF THE EXPRESSION OF THE MAIN SPECIFIC GENES IN THE BIOLOGICAL PROCESSES BY RT-PCR (POLYMERASE CHAIN REACTION IN REAL TIME).
