Biological Degradation of Pollutants

The Secondary Treatment Plant uses biological processes to break down dissolved and suspended organic matter in wastewater. After primary treatment, microorganisms in the secondary treatment phase consume the organic pollutants, converting them into stable, non-harmful by-products.

Efficient aeration and mixing systems are essential to maintain optimal conditions for microbial activity, ensuring the pollutants are broken down effectively. Secondary treatment plants play a vital role in improving the water quality before it moves on to the final stage of treatment or discharge.

Key Features of Secondary Treatment

• Biological degradation of pollutants, using microorganisms to decompose organic matter
• Significant improvement in water quality, making it suitable for further treatment or discharge
• Reduced environmental impact, contributing to cleaner ecosystems
• Preparation for tertiary treatment or safe discharge into natural water bodies
