Mill Leakage is the significant and unnecessary loss of fiber, energy and water that usually goes unnoticed in most pulp and paper mills. In-mill studies uncover the improvement potential, identify the solutions and provide the business case for remedial action. Examples from studies that are performed using rotary drum microfilter technology quantify the unnecessary losses from mill leakage. Once the extent of possible reduction is demonstrated and its economic value is established, a credible path forward can be put in place. The solutions include saving fiber and energy while reducing fresh water usage and effluent discharge. An extended benefit from the solution is the reduction in demand on the bio treatment processes as well as lower BOD/COD.
