Case Study #1

Wave

 Pulp and paper industry

Figueira da Foz, Portugal

Pulp and paper industry

Background

  • Only 20% recovery of 1.75 Mm3/year of industrial wastewater from pulp bleaching

  • No heat recovery from 75 ºC.+
  • Valuable solids and substances without recovery in the current wastewater

  • No energy recovery from industrial wastewater treatment

Expected benefits

  • Reduce water consumption by up to 95% in the bleaching process and reuse waste heat
  • Implement real-time monitoring of critical process parameters
  • Minimise waste through the recovery of cellulose fibre and lignin from water

Latest developments

  • Laboratory scale tests in course for membrane and oxidation technologies
