Aries Improves Paper Mill Raw Water Quality To Increase Sheet Brightness
Posted in
A paper mill found that it needed better raw water quality to produce a new brighter white grade. The mill’s existing system treated river water with coarse screens and bleach addition. The maximum brightness that could be produced with this process was approximately 80. Aries Chemical was asked to provide a solution to improve the mill’s raw water treatment process. Aries surveyed the paper mill’s existing raw water treatment system and sent raw water samples…

Posted in
A recycled papermill treats approximately 1.4 million gallons of process wastewater per day. The wastewater has high BOD levels. Wastewater is processed utilizing an anaerobic digester followed by an aerobic activated sludge system. The activated sludge system is clarified with a dissolved air flotation clarifier prior to discharge. Urea and phosphoric acid are added to the system to provide nitrogen and phosphorus as nutrients. Caustic Soda was historically used to control pH and alkalinity in…

Posted in
After changing recycled furnish to include newsprint, a paperboard mill began experiencing significant difficulty in keeping its press felts clean and open. Speed on the machine was impacted and felt life decreased. Picking and sheet breaks were more common and downtime increased. The more frequent felt changes increased manufacturing costs and further increased downtime. The incumbent supplier was asked for help. Their response time was slow and solutions were not forthcoming. The mill personnel actually…
