Effluent - GCSE Chemistry Definition

Effluent is the term used to describe waste water that is released from factories, sewage works, and industrial sites into water bodies like rivers, lakes, and seas. In GCSE Chemistry, it is important to understand that effluent can contain harmful chemicals, bacteria, or pollutants. Therefore, it must be treated before being released into water bodies to prevent environmental damage. (Treatment is the process of cleaning and removing harmful substances from the effluent.) If not treated properly, it can pollute water, harm aquatic life, and spread diseases. Therefore, managing effluent is crucial to ensure that our water resources remain clean and safe.
