Course Pack: Treatment Foundations
Lifting the Veil
Course Description
This module examines chemical dosing challenges including deterioration,
delivery variability, residual drift, and regulatory expectations. Learners learn workflows for
monitoring, adjusting, troubleshooting, and documenting chemical feed decisions.
Learning Objectives
1) Explain how dosing adjustments affect compliance and performance
2) Identify risks from chemical deterioration, delivery variance, and residual drift
3) Apply troubleshooting steps for dose maintenance and delivery problems
4) Align dosing decisions with monitoring data and regulatory expectations
5) Create documentation that supports audits and corrective action reviews
Agenda
1) Dose fundamentals: what operators control and what can go wrong
2) Chemical delivery and storage: deterioration and variability risks
3) Residual management: maintaining targets and minimizing excursions
4) Adjustment workflow: monitoring → decision → action → verification
5) Regulatory-ready documentation: logs, calculations, justifications
