Biological Treatment - GCSE Geography Definition

Reviewed by: Bridgette Barrett

Last updated

Biological treatment, in the context of GCSE Geography, refers to the process of using microorganisms, such as bacteria, fungi, or protozoa, to break down organic matter in waste materials, especially in sewage or contaminated soil and water. This natural process is a crucial component of managing and treating waste sustainably. Biological treatment is commonly employed in sewage treatment plants, where it helps in purifying water by removing organic pollutants before the water is released back into the environment, ensuring ecosystems are protected and water resources remain safe for humans and wildlife.
