Papermaking

In pulp and paper production, the switching of fiber raw material types, chemical residues in bleaching sections, and instantaneous fluctuations in wastewater discharge indicators directly determine product whiteness, strength grade, and environmental compliance costs. The fully automatic intermittent chemical analyzer adopts an integrated closed-loop design of "sampling reagent addition reaction detection cleaning", integrating reagent refrigeration and constant temperature reaction modules. It can synchronously measure key indicators such as ammonia nitrogen and phosphate in pulp making process water, paper machine white water, and end wastewater, helping paper companies move from empirical regulation to data-driven green manufacturing.
