Disposal of the sludge that results from primary treatment of waste waters generated during the manufacture of coated and/or filled papers has caused many problems. A process has been developed and tested in a full scale mill trial wherein the pigment present in the waste sludge was reclaimed through incineration of the volatile components of the sludge. In essence, the process consisted of operations in which the sludge resulting from the primary treatment process was diluted to less than 0.75% solids, centri-cleaned, dewatered to 30% solids, shredded, dried, and burned in a rotary kiln. The ash that resulted - the pigment - was then pulverized and used as filler pigment in the papermaking process. The process was shown to be economically unfeasible at the present time. |
