Design and development of water treatment methods for improving water quality of KCAET campus

Abstract

Maintaining the quality of drinking water in the KCAET campus has been a challenging task from the inception of the college. The main objective of this work is to improve the quality of drinking water in the KCAET campus. In this work, a simple tap water filter was designed and fabricated as an immediate solution to improve the drinking water quality. Locally available materials like charcoal, sand, coir fibres and tile pieces were used inside the tap water filter used for filtering the water. A quality analysis of the filtered water was also done. Experiments were done for different combinations of filtering materials. The result of the study reveals that the filtering unit with charcoal, tile pieces and sand combination is found to be most effective in removing colour, iron content and turbidity and maintaining the pH value. As a long term solution to the water quality problems, a design of a water treatment plant complete with sedimentation, filtration and disinfection units were also proposed in this work. The water treatment plant was designed for the future requirement after thirty years. A ground level storage reservoir for temporary storage of treated water was also designed.
