ETP Assessment

ETP Assessment chapter added. Focusing on Effluent Treatment Plants (ETPs), this chapter highlights their essential role in treating industrial wastewater from textile and leather production. It explains how efficient ETPs ensure effluent meets quality standards and prevent negative environmental and health impacts.

In textile and leather manufacturing, significant amounts of water and chemicals are consumed throughout production. After use, this water is treated and released as wastewater or effluent into the environment. When the wastewater fails to meet quality standards, it can negatively affect ecosystems — harming biodiversity, aquatic organisms, and even human health.

To prevent such impacts, textile and leather facilities must operate an effluent treatment plant (ETP) that removes or reduces harmful pollutants in the wastewater to acceptable levels before discharge. The main objective of an ETP is to ensure that industrial wastewater is treated effectively, safeguarding both the environment and public health.

ETP assessments apply to facilities that discharge wastewater directly and conduct testing of wastewater and sludge in accordance with the ZDHC Wastewater and Sludge Guidelines. (Note: The threshold flow rate of 15m³/day does not apply to ETP assessments.)
