Sewage refers to wastewater, which can contain contaminants from household, commercial, and industrial sources. Sewage treatment is a process designed to remove these contaminants and purify the wastewater before discharging it into natural water bodies. It involves several stages:
Sewage treatment plays a crucial role in safeguarding public health and the environment:
Prevents Water Contamination: Untreated sewage carries harmful bacteria, viruses, and parasites that can pollute water sources, potentially causing waterborne diseases.
Protects Aquatic Life: Pollutants in sewage can harm aquatic life, disrupt ecosystems, and deplete oxygen levels in water bodies.
Reduces Environmental Degradation: Improper sewage disposal can contaminate soil and groundwater, leading to land degradation and health hazards.
Conserves Resources: Sewage treatment helps reclaim and reuse water, conserving a precious resource in water-scarce regions.
Promotes Health and Well-being: Access to proper sanitation and clean water is essential for preventing diseases and improving overall health.
