According to its “Green Soul”, STC develops process for the drastic reduction of the consumption of water from natural resources by maximizing, whenever possible, the reuse and internal recycling of water for industrial purposes.  The creativity of our engineers and our wide experience allows STC to identify process solutions to meet the Zero Liquid Discharge (ZLD) philosophy, thus reducing the water consumptions and increasing the Industry sustainability.

The identification of the best possible solutions starts from the deep analysis of the productive cycles in order to understand the water quality requirements and the effective possibilities of water reuse.

After the traditional water treatment process, to close the loop and the water cycle, membrane for advanced filtration and evaporative technologies are applied to achieve the ZLD target such as:

  • Pre-concentration through membrane brine concentrators or electrodialysis (ED)
  • Evaporation/Crystallization with high efficiency
