Dissolved air flotation system improves wastewater treatment at Glatfelter

Biological wastewater treatment technology has been used at Glatfelter's Neenah facility since 1976 to treat the wastewater resulting from operations, but, approximately seven years ago, the facility began experiencing problems with its biological treatment system, resulting in substandard wastewater effluent. By modifying its wastewater treatment system to incorporate a new dissolved air flotation system, the Neenah mill has been able to meet its production goals and wastewater discharge guidelines. Glatfelter's environmental personnel consulted with USFilter's Envirex products on the best possible solution, and retrofitted the mill's existing dissolved air flotation (DAF) thickener with a Folded Flow DAF separator. Personnel at Glatfelter's Midwest facility continue to research advanced deinking methods and wastepaper recycling technology and are proud of the fact that they have committed to alternative uses for the solid waste generated by the facility.
