Reuse of Process Effluents.

Reduce fresh water intake by reusing internal streams

Goal and Strategy

Stimulate development of new breakthrough technology concepts and projects to reduce average water usage by half by 2030.
  • Identify target areas for reuse and establish water quality requirements.
  • Develop cost-effective, broadly applicable technical solutions to address contaminants that inhibit the reuse of process effluent streams. 
Picture
R&D Needs 
Paper machine Whitewater Reuse:
  • Develop cost-effective, operationally reliable technologies for the removal of suspended solids, especially in the 10-40 micron range
  • Develop cost-effective technologies for the control or removal of dissolved colloidal substances
  • Develop technology to effectively remove inorganic constituents (total dissolved solids and calcium) that cause scaling issues​​
Reuse of Biologically Treated Effluents:
  • Determine a process for cost-effective reuse of biologically treated effluent in bleach plant applications
  • Demonstrate the compatibility of treated effluents from five broad categories of mills with various process applications within these mills​

High-Priority Initiatives
Model development - Development of a predictive model to determine the possible water reuse options in the mill and corresponding ROI
Status: Concept paper describing the needed predictive model was broadly circulated for review and response/proposals from external experts.  The paper has generated some interest and several proposals to perform the modeling were received and are being evaluated.

The team plans a “Water Summit” workshop in 2019 to identify technical and non-technical impediments to increased water recycling in the paper mill, as well as the drivers that encourage manufacturing locations to increase their water recycling.
