Nitrogen and Phosphorus Nutrient Loading in Effluent
topic
Total nitrogen analysis by persulfate digestion followed by colorimetric measurement and total phosphorus by molybdenum blue spectrophotometry quantify the nutrient loads discharged from textile sizing, printing paste, and auxiliary chemical operations that contribute to eutrophication of nitrogen and phosphorus-limited receiving water bodies when inadequately treated.
Role
Monitors eutrophication risk from textile process effluents containing starch-based sizing agents, nitrogen-rich dye bath residues, and phosphate-containing detergent formulations, addressing water quality requirements under the EU Water Framework Directive and national eutrophication-sensitive watercourse protection requirements.
