An Industrial Visit to the Selaulim Water Treatment Plant

On 18th September 2025, the Second-Year Electronics and Computer Science (SE ECS) students visited the Selaulim Water Treatment Plant as part of their academic curriculum. The visit was organized to provide practical insights into large-scale water purification processes.

The plant, with a treatment capacity of 96 million liters per day, employs alum, lime, and chlorine to purify water for domestic use. Students were guided through the major stages of treatment, including:

• Intake and Screening: Removal of large debris from raw water.
• Coagulation and Flocculation: Addition of chemicals to bind fine particles.
• Sedimentation (Clariflocculation): Settling of flocs as sludge.
• Filtration: Removal of fine particles and microorganisms using sand, gravel, and activated carbon filters.
• Disinfection: Chlorination to ensure safe potable water.
• Storage and Distribution: Storage in reservoirs followed by supply through pipelines.
• Sludge Management: Safe disposal of accumulated sludge.

The students also observed operational practices such as chemical dosing, filtration backwashing, valve control, and quality monitoring, which effectively bridged classroom theory with real-world applications. The visit emphasized the importance of sustainable water management in ensuring public health and community welfare.

The Department extends its gratitude to the college management and faculty members, especially Prof. Kimberly Morais, Mrs. Trima Fernandes e Fizardo, and Mrs. Michelle Araujo e Viegas, for their guidance throughout the visit. Special thanks are also due to Mr. Naryan Kumar and Ms. Ashmita Gaonkar for their expert explanations and valuable insights.
