Paper Mill Water Closure: A Success Story

0
Today the Pulp & Paper and Wood Products Industries are faced with tightening water quality and volume discharge regulations. Whether discharging to a local treatment facility or discharging to a river the economic impact is substantial. This article outlines a typical situation where the production facility utilized the latest expertise and most efficient  equipment to cost-effectively achieve their water management goals.

APC Paper of New York produces specialty Kraft grades from recycled fiber. The Mill was faced with meeting new water discharge standards put in place by the New York Department of Environmental Conservation (NYDEC). The facility met all the new requirements except for Biochemical Oxygen Demand (BOD). To meet these guidelines the Mill commissioned consultants to review the process and determine the most cost-effective strategies to meet the new stringent requirements.

The Mill received recommendations and quotations to install a $1,200,000-$1,400,000 treatment system expansion. In addition to upgrading primary clarification, the Mill would be required to install a 500 GPM Secondary (Biological) treatment operation to meet the environmental regulations. After evaluation of the facilities process and regulatory requirements, World Water Works proposed a process water reuse approach that involved upgrading their present process Dissolved Air Flotation (DAF) system and installing advanced Microfiltration.
