VSEP helps box and bag plant meet discharge limits and pre-concentrates starch prior to evaporation
The manufacture of corrugated boxboard and paper bags is a major industry in the United States and elsewhere. There are about 1,500 corrugated box plants and a similar number of bag plants in the United States. Because of its relatively low cost and high strength characteristics, corrugated board has become the prime structural material for the manufacture of boxes and shipping containers. Linerboard materials and paper are used to manufacture corrugated boxes and paper bags. Corrugated paperboard is a sandwich structure formed by gluing a fluted corrugating medium ply to two linerboard facings. The disposal of wastewater generated in a box or bag plant has become a problem due to the high levels of organics primarily resulting from glue starch and heavy metals.
