R&D Needs
Paper machine Whitewater Reuse:
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.
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
- 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
