Pulp & Paper
The Pulp & Paper industry is among the most intensive industrial water users. Pulp & paper mills produce large volumes of wastewater and residual sludge. In these conditions, wastewater treatment, discharge, and sludge disposal (when it cannot be reused) are critical issues.
Contaminants are different depending on the process and the final product (tissue, cardboard, or special paper). They can include suspended solids (fibers, minerals, colloids), chlorinated organic compounds, dissolved solids, chemical oxygen demand (COD), and biological oxygen demand (BOD).
Water is essential and crucial for pulp & paper production. For this reason, water treatment packages for inlet water have to be reliable and respect all conditions.
