Removal Efficiency

Definition

Removal efficiency refers to the effectiveness of a wastewater treatment process in eliminating specific pollutants or contaminants from wastewater. It is typically expressed as a percentage, indicating the proportion of a target substance removed compared to its initial concentration. High removal efficiency is crucial for meeting regulatory standards and ensuring the safe discharge or reuse of treated water.
