Pulp and Paper industrial standards as well as environmental and economic factors are increasing the interest in progressing toward low effluent, closed-cycle kraft mills. Accumulation of non-process elements (NPE’s) is widely recognized as a major limitation to zero discharge mill operation.

Eco-Tec’s chemical recovery/purification Systems based on Eco-Tec’s Recoflo® ion-exchange technology offer the most efficient approaches available for separation/removal of contaminants and recovery of valuable elements.


  • Significantly lower capital and installed cost
  • Lower operating cost
  • Better sulfate and carbonate recovery efficiency
  • High chloride and/or Potassium removal efficiency
  • Significantly less floor and head space
