Vibrio cholerae dynamics in drinking water; mathematical and statistical analysis

Cholera is deadly watery diarrhea caused by Vibro cholerae. Approximately 550,000 Pakistani children die each year due to waterborne illnesses including diarrhea. Vibro cholera bacterium strain O1eLtOR is a major cause of diarrhea in Pakistan. Since it is a waterborne bacteria, people relying on tap water (not filtered) are the most vulnerable to this disease. In current study, tap water was disinfected by using different concentrations of sodium dichloroisocyanurate (NADDC) to devise an effective and inexpensive method to make water safe for drinking. Different concentrations of NADDC were utilized to disinfect water and 1.2 mg of NADDC in 40 ml water was effective to disinfect water from bacterial colonies The experimental data is represented through the proposed mathematical model i.e. exponential decay model and statistical analysis of the generated data is also done. The graphical representation is also done to show the exponential decay of bacterial growth. The results of our study reveal that NADCC is an effective chemical agent to purify drinking water from Vibrio cholerae.
