Water Management for Pulp & Paper Operations
Pulp and paper mills generate large volumes of wastewater containing fibres, fillers, dissolved organics, and chemicals. Our treatment solutions focus on fibre recovery for operational benefits, whitewater clarification for process efficiency, and effluent treatment for environmental compliance. Saveall fibre recovery, dissolved-air flotation and biological treatment recover usable fibre and water while bringing effluent within consent. Reynolds & Bauhm design these systems to close the mill’s water loop, cutting fresh-water demand and effluent volume together.
Efficient recovery of valuable fibres from whitewater and effluent streams, reducing raw material costs and improving sustainability.
