Description

The adverse effect of the residual antibiotics and disinfectants on the population of helpful bacteria to avoid the septic failure is receiving considerable attention in the United States as 30 % of the residents live in rural areas and rely on septic system. Three treatments of amoxicillin only, bleach only and a combination of bleach and amoxicillin applied to the modeling of static flow system along with a daily load of nutrient broth will identify the right chemical and antibiotic concentration amount that would cause a significant reduction in the bacterial activity. The Most Probable Number (MPN) and Biochemical Oxygen Demand (BOD) tests carried out on initial and final conditions to enumerate the bacterial population is used to determine the organic content representing the population of bacteria. In particular, among three treatments, the combination of chemical and antibiotic dose is seen more efficient treatment than just pure chemical or antibiotic.
