Action 06: Alternative uses of “final salt product” and “vapor condensate” from the brine treatment system – Market opportunities in Greece

Duration:01/07/2011 - 31/12/2013 (18 months)

Status: Completed

Action 6 consists of the following activity:

Activity 6(a): Alternative uses of the system’s final products

In Activity 6(a), case studies were examined for industrial applications with Zero Liquid Discharge (ZLD) systems applied. More than 7 case studies were examined, producing brine effluents of similar chemistry with brine from desalination plants. Brine effluents are the by-product produced by water or/and wastewater treatment operations. Some of the industries producing brine effluents include, but are not limited to, the following: 

  • Desalination facilities;
  • Energy production (flue gas treatment and cooling water blowdown);
  • Food industry;
  • Leather industry and textile;
  • Oil and gas industry;
  • Chemical industry (including biotech and pharmaceutical);
  • Mining industry;
  • Pulp and paper.


These case studies allowed to assess how the products of such systems are exploited in these sectors. This data has been incorporated in Deliverable 6.1.

Activity 6(b): Local and Regional market opportunities of the end-products

At the first stages of the Activity 6(b) the following have been investigated: (a) local needs for dry salt and high quality distilled water (tonnage quantities yearly consumed by product); (b) list of consumers; and (c) market specifications and prices. The market research was extended on a regional basis and in particular for the neighboring islands of Northern Cyclades: Siros, Andros and Mykonos. The quantities of salt and water produced both by the pilot system and its full-scale development were estimated at first. The scope was to examine whether these quantities suffice to supply local or/and regional needs. Given that no recordings for salt consumption were available, estimations were made on the basis of coherent assumptions regarding consumption rates per capita, in order to derive total salt consumption per case study examined. Water data and local markets of salt are examined thoroughly for the case of Tinos. This information provides the basis for estimating the potential to cover local or even regional needs of these two goods (water and salt) through the use of a full-scale system. For this to be determined, data for the three neighbouring islands were necessary. This data was collected by communications with the competent authorities (Water Departments of the neighbouring Municipalities). Based on the data collected, a possible market network between these islands, as well as for the Cyclades complex as a whole.

This data has been incorporated in Deliverable 6.2.
