Upgrade of existing waste water treatment equipment

Project goal

Reuse of the waste water after treatment


  • Upgrade of existing treatment of waste water  coming from cleaning processes in admixtures production with a new complementary equipment to reuse the treated water
  • New equipment include ultrafiltration phase and nanofiltration phase through ceramic membranes
  • Parameter setting to achieve required water quality
  • Installation a water meter to measure water savings


  • Quality of treated waste water allow to reuse it in cleaning processes of loading bulk station and in water treatment plant too
  • Significant savings of fresh tap water consumption of 200 m3 per month (- 25%)
  • Less stringent site controls by authorities due reduced waste water throwing to sewer and better quality
