The DVGW

Your network of excellence in the gas and water industry

The DVGW supports the gas and water industry in all technical and scientific areas. The main focus of the Association’s work is on safety and hygiene as well as environmental and consumer protection. The DVGW elaborates technical rules designed to promote the technical self-management of the German gas and water industry, thus ensuring the safe and secure supply of gas and water according to the highest international standards. The Association, which was founded in 1859, currently has approximately 14,000 members. The DVGW is free from economic and political influences.

Water analytics

Analytics and other services

in the field of water chemistry and water technology

The field of water chemistry and water technology provides comprehensive analytical methods for characterising aqueous solutions and sludges. This includes sum parameters as well as high-performance analytics and microbiological tests, such as flow cytometry. Beside this, we are also experts in water treatment (drinking water, waste water, process water, among others). We support and manage tests on a laboratory and pilot scale and also advise on the next steps.
Physico-chemical and sum parameters
  • TR/oTR and TS/oTS, unfiltered and filtered dry matter and organic dry matter
  • pH-value, electrical conductivity, oxygen content
  • Turbidity
  • COD (chemical oxygen demand) via cell test
  • BODn (biochemical oxygen demand after n days) via dilution method
  • TOC, DOC and TN, total and dissolved organic carbon content and total nitrogen
  • AOX (adsorbable organically bound halogens)
  • Photometry in the UV/vis range, (SAK254 nm and SAK436 nm (colouring))
  • Fluorescence with excitation emission matrix (EEM)
  • Anions, cations and volatile organic acids via IC
  • Cations, heavy metals and metalloids via ICP-OES, AAS
  • PAH and VHHC via GC-MS and GC-ECD
  • Trace substances (e.g. pesticides, antibiotics, other analytes as requested) via HPLC-MSn, HPLC-DAD)
  • Further characterisation of organic carbon via gel chromatographic fractionation (SEC with online detection of the organic carbon and UC, fluorescence and nitrogen detection)
  • Gas analysis via GC (e.g. CH4, CO2)
  • Flow cytometry
  • Fluorescence microscopy (epi, CLSM)
  • Optical coherence tomography (OCT)
  • Characterisation of membranes, membrane modules and membrane processes:
    • Microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), reverse osmosis (RO)
    • Membrane bioreactors (MBR)
    • Membrane distillation
    • Electrodialysis
  • Membrane autopsies and characterisation of surface layers
  • Consultation and recommendation on the application of membrane processes
  • Laboratories for experiments under defined test conditions and temperatures (e.g. 4 °C)
  • (Bio)reactors
  • Automatic Methane Potential Test System (AMPTS)
  • Description of microbial communities (e.g. substance conversion, antibiotic resistances)
  • Sunlight simulator
