Drinks Industry

Wastewater quality and process concepts

The alcohol-free drinks industry (soft drinks and fruit juice industry, mineral wells and springs) and breweries mainly produce productionwastewater, coolingwater and sanitary wastewater from various areas of origin. The wastewater constituents from the soft drinks industry and mineral wells and springs are: Glue and fibrous substances, alkali and acidic cleaning solutions with organic contamination, sugar and product losses as well as product residues from returnable bottles. The wastewater of breweries, depending on the drinks produced, contains different concentrations of carbohydrates and proteins.

The wastewater from the alcohol-free drinks industry and breweries is mainly fed into public mechanical-biological wastewater plants. The organic substances in the abovenamed wastewater are readily biologically degradable and can therefore be treated successfully together with householdwastewater.

In-house treatment of the production wastewater with subsequent direct discharge into a receiving water in Germany requires compliance with the minimum requirements of the wastewater regulations (Abwasserverordnung – AbwV) Annex 6 (production of soft drinks and bottling) /Annex 10 (breweries).

The following process steps are used generally for treatment of wastewater from drinks industry and breweries:

Process steps:

  • Mechanicalwastewater pretreatment
  • Grease separation/flotation
  • Storage and homogenisation
  • Neutralisation
  • Biological treatment
    • Anaerobic wastewater treatment
    • Aerobic wastewater treatment (SBR/MBR plants)
  • Filtration
  • Sludge treatment and energy generation from biogas
  • Waste air treatment
  • Automation (E-I&C technology, process and remote monitoring, etc.)

We offer turnkey, integrated solutions and individual concepts forwater andwastewater treatment in the drinks industry and breweries.

The optimum process technology is selected, taking into consideration the operational requirements, the need to minimise disposal quantities and energy consumption and/or to generate energy. This technology can be used for the respective wastewater composition and results in the required discharge limits.

We unites all technical know-how required to implement technical industrial water treatment tasks. From individual advice, development, to production, installation, commissioning, through to maintenance/service and optimisation, we work with strong partners.
