This introductory module defines scouring and provides an overview of the scouring process. It explains the importance of scouring in wool processing and identifies the compromises and factors that influence the scouring process.

This module covers the contaminants found in raw wool and explores their classifications and properties, and the factors affecting contaminant levels.

This module outlines the steps taken to prepare wool for scouring including a review of the scouring process. These steps include preparing wool blends, bale warming, blend layouts, opening raw wool and best-practice issues during the scouring preparation operation.

This module explores the purpose and types of surfactants used in wool processing. It explains basic detergency and how contaminants are removed from raw wool during scouring. It also explains the concept and causes of entanglement, the impact of this on further processing of wool and the methods used to reduce entanglement during scouring.

This module covers the mechanical elements of the scouring process including the scouring line configuration, the wool transport system, the liquor handling system and scouring bowl design.

This module covers the process variables of the scouring process including the scour configuration, water, temperature ranges, surfactants, builders and other chemical additions.

This module explores the principles of contaminant recovery including solid–liquid separation and liquid–liquid separation.

This module explores the practices of contaminant recovery, including the use of dirt recovery devices in wool scouring and methods for both dirt recovery in rinsewater and wool wax recovery.

This module covers the environmental issues associated with scouring and the pollution propensity of contaminants. It also explores sludge treatment and disposal, choosing a wastewater treatment, market pressures and best practice issues associated with wastewater management.

This module covers the importance of process control and explores the process controls relating to the scouring line. It also explores the principles of quality control including analysis programs and methods.
