WINE CELLARS

THE PROBLEM OF WINE CELLARS

Wine cellars waste water comes from washing winemaking equipments, barrels and bottles, and from the winemaking plants pasteurization. The amount of waste water is expected to vary according to the yearly quantity of grape worked upon and the kind of activities executed.  Although  wine cellars untreated wastewater is expected to mainly contain organic substances, it may damage to the quality of the soil or of surface water,  as well as to the public sewer system. The purification plant has to be dimensioned to the effluent final receiving body; plus it has to guarantee an abatement level of the pollutants complying with seasonal activity peaks.

To be as effective as possible, the purification process has to be arranged with an automatic screening system, an equalization stage, that is required to balance the fluctuations in the pollutants concentration, and – most of all – to provide  an abatement level  of suspended solids and organic compounds that complies with any else functional parameter regulating the biological process, especially during seasonal peaks.  The bio-oxidation stage represents the heart of the system and can be integrated with a refining stage finalized to reuse the effluent for irrigation. The plant is custom built from DEPURECO and the layout is conveniently drawn in order to take no more than the space strictly required to allow the plant management and maintenance operations.

STANDARD PROCESS

  • Automatic fine screening
  • Aerated homogenization
  • Clariflocculation (high season)
  • Oxidation by carbon-supported enzymes bio-clariflocculation
  • Sedimentation
  • Disinfection
  • Aerobic stabilization of excess sludge
  • Excess sludge dehydration

DEPURECO wastewater purification plants oriented to wine cellars:

  • Provide flexibility (adaptable to seasonal ups and downs)
  • Require the user to sustain low operational costs
  • Quick start (they quickly get up to the full speed, that is a crucial goal, since grape harvest is a short-lasting activity)
  • Are made of chemical resistant materials
  • Outperforms the same size domestic waste water treatment plants
  • Provide treatments preparatory to the biological one
  • Prepare to the treatment of water containing sulfur dioxide and derivates

The suitable plant size is conveniently set after checking the factory operating parameters, that change from one to another. Due to its own 40 years experience DEPURECO is able to come up with the most effective solution to meet desirable purification standards.
