Corrugated packaging manufacturers have to deal with two issues. One is a color removal issue typical of printing operations. The other is starch issue that is associated with the adhesives used in the manufacturing process. Starch is soluble and therefore gives rise to dissolved solids that have a high BOD level. Starch also carries a strong anionic charge, making the water difficult to treat.
Northland Chemical has developed products and methods designed to deal effectively with the wastewater treatment challenges of corrugated packaging producers.
